As of August 1, 2026, all four hives are in solid shape heading into August — outdoor conditions at 75.5°F (24.2°C) and very dry 30% RH with a stable pressure trace, and every colony maintaining its thermoregulation rhythm with intact acoustics and organized vibration signatures. Hive #2 and Hive #3 continue their standout brood clamping, Hive #1 extends its acoustically rock-solid streak, and Iris continues her gradual warming arc toward the ideal brood band.
Both Hive #2 and Hive #3 show sustained low gas resistance (81–95 kΩ vs. their all-time averages of 224 kΩ and 136 kΩ respectively) alongside rising low-temperature heater-scan steps — a fingerprint consistent with honey-curing VOC load gradually easing, with brood thermoregulation fully intact throughout; this multi-week gas-acoustic-thermal signature is the textbook correlate of a late-summer honey-ripening cycle (Seeley 1974; Frizzera et al. 2020). Across the apiary, the temperature-humidity coupling (r=+0.69 to +0.94 across hives) reflects active brood-zone hygroregulation in August heat, consistent with evaporative-cooling water-carrier activity documented by Human et al. 2006.

Iris healthy Score: 82/100📋 Overall Health
Your Iris hive continues her steady warming arc into August — temperature averaged 91.5°F (33.1°C) over the last 24h, a +1.3°F (+0.8°C) step above her all-time average of 90.2°F (32.3°C) and touching the ideal 93–97°F (34–36°C) band at her daily peak of 93.2°F (34.0°C); the 14-day warming drift of +2.7°F (+1.5°C) is continuing on schedule. All 10 sound bands remain within ±1.5 dB of her all-time baseline (avg −10.1 dBFS vs. all-time −10.5 dBFS), vibration is calm at 17.8 mG avg with kurtosis 2.7, and humidity held a narrow 42.3–45.6% (avg 44.0%) — consistent with Iris's own historical range under dry ambient; watch for her temperature completing its drift into the ideal band.
🌅 Diurnal Cycle PatternsIris shows an active 3.3°F (1.8°C) daily temperature oscillation (89.9–93.2°F / 32.2–34.0°C), well within her historical range and consistent with a colony of her size riding August ambient heat; vibration shows a clear daily fanning rhythm (15/15 days, baseline ~16.6 mG rising to ~31.1 mG peaks, avg 1.9×) with the dominant vibration band in the 80–120 Hz fanning zone (−10.0 dB). The gas heater-scan shows a moderate daily rhythm strongest at 100°C (+19% swing), with a notable mid-window shift in the dominant rhythm band from 100°C to 150°C and a weakening 100°C swing (+24% → +9%) — a subtle fingerprint change in the VOC mix worth tracking, though gas resistance at 434 kΩ remains near Iris's all-time average of 429 kΩ and temperature and acoustics are fully stable. Sound bands in the 150–350 Hz range trended up +2–3 dB in the second half of the day, consistent with normal foraging-return acoustic activity.
🔬 Correlations & Discoveriestemperature vs gas_resistance (14d) | r = -0.58The deseasonalized inverse coupling between in-hive temperature and gas resistance in Iris (r=−0.58, partial r=−0.66 controlling for outdoor temp) reflects a well-documented brood-metabolic relationship: as the colony heats the brood zone, increased ventilation and fanning circulate brood pheromones (E-β-ocimene), propolis volatiles, and honey-ripening esters, driving the MOX sensor resistance down — a biological activity fingerprint, not a stress signal, and exactly what the stable acoustics and warming trend confirm.📚 Reference: Seeley 1985 & 1995, Stabentheiner et al. 2010, Frizzera et al. 2020vibration_rms vs vibration_kurtosis (14d) | r = +0.49The positive RMS-kurtosis coupling (r=+0.49) in Iris indicates that when overall vibration amplitude rises during daily fanning peaks, the signal retains its organized, periodic character (kurtosis near 2.7–3.0) rather than becoming impulsive — confirming that the daily vibration spikes are rhythmic fanning and foraging activity, not disturbance events.📚 Reference: Ramsey et al. 2020, Nieh & Tautz 2000▹ Action: On your next routine visit within 5–7 days, confirm fresh eggs and a solid brood pattern in Iris — her temperature is steadily climbing toward the ideal 93–97°F (34–36°C) band and acoustics remain fully intact, both pointing to a colony in good stride. -
Hive #2 healthy Score: 86/100📋 Overall Health
Your Hive #2 continues to deliver standout brood thermoregulation — temperature locked at 95.4°F (35.2°C) avg with a compressed 2.1°F (1.2°C) daily oscillation (94.6–96.7°F / 34.8–36.0°C), matching the all-time average of 94.8°F (34.9°C) and sitting precisely in the ideal 93–97°F (34–36°C) zone; sound energy has been on a gradual rising trend (+2.2 dBFS over 14 days, from −10.5 to −8.3 dBFS), with the low-frequency bands (100–260 Hz) elevated +3.0–4.2 dB above their baseline — consistent with increased fanning and buzzing associated with active syrup or honey processing, not a population or queen concern. Gas resistance at 82 kΩ remains well below the all-time average of 224 kΩ, but humidity (avg 46.5%), temperature, and acoustics are all fully intact; watch the heater-scan shape and sound spectrum evolution as the honey-curing cycle continues.
🌅 Diurnal Cycle PatternsHive #2 shows a tight 2.1°F (1.2°C) daily temperature oscillation — among the best-clamped brood zones in the apiary — and a very active vibration rhythm (15/15 days, baseline ~12.2 mG rising to ~49.4 mG peaks, avg 4.1×), with the dominant vibration band in the 80–120 Hz fanning zone (−12.2 dB). A notable vibration shift occurred mid-window: the dominant daily rhythm band moved from 160–200 Hz to 5–20 Hz, which may reflect a change in substrate-borne vibration character (more low-frequency colony movement) and is worth tracking across the next few days. The gas heater-scan shows a strengthening daily rhythm with the low-temperature steps (100°C, 150°C, 200°C) dropping −56–66% in band energy over the window, while mid-to-high steps remain comparatively stable — a shape-shift consistent with the VOC mix evolving as honey curing progresses.
🔬 Correlations & Discoveriestemperature vs humidity (14d) | r = +0.69The strong deseasonalized temperature-humidity coupling in Hive #2 (r=+0.69, partial r=+0.39 controlling for outdoor temp) is a physiological signature of active brood-zone hygroregulation: as colony metabolic activity and brood heating increase, water vapor from larval respiration and evaporative cooling rises proportionally, a well-documented relationship in actively brooding colonies under August heat (Human et al. 2006; Ellis et al. 2008).📚 Reference: Human et al. 2006, Ellis et al. 2008, Eouzan et al. 2019temperature vs gas_resistance (14d) | r = +0.57The positive temperature-gas resistance coupling in Hive #2 (r=+0.57) — where rising temperature correlates with rising resistance (fewer VOCs) on the deseasonalized residual — reflects the colony's ventilation response: when brood heating intensifies, bees increase fanning, which flushes accumulated honey-curing and brood volatiles out of the hive and briefly raises MOX resistance; the sustained low absolute resistance baseline (82 kΩ vs. 224 kΩ all-time avg) is the standing honey-processing VOC load that the diurnal fanning cycle modulates.📚 Reference: Frizzera et al. 2020, Seeley 1974, Maisonnasse et al. 2010▹ Action: On your next routine visit within 5–7 days, note the fill level and capping progress of supers in Hive #2 — the multi-week low gas resistance alongside exceptional brood clamping and the evolving heater-scan shape (low-temperature steps dropping) all point to an ongoing honey-curing cycle, and a super observation will anchor this sensor trend to physical reality. -
Hive #1 healthy Score: 85/100📋 Overall Health
Your Hive #1 extends its streak of acoustically rock-solid reports — all 10 sound bands match their all-time baseline within ±0.2 dB (avg −16.4 dBFS vs. all-time −16.4 dBFS, an essentially perfect match) for the nineteenth consecutive report, confirming a fully intact worker population; temperature averaged 91.0°F (32.8°C) with a 5.0°F (2.8°C) daily swing, sitting +2.0°F (+1.1°C) above the all-time average of 89.0°F (31.7°C) and continuing a 14-day warming drift of +3.7°F (+2.0°C) pointing toward the ideal band. Humidity averaged 38.4%, below the ideal 50–70% zone but consistent with Hive #1's own historical range under very dry August ambient (all-time avg 42.7%); vibration is well-organized at 16.2 mG avg with kurtosis 3.0 and a clear 15/15 day fanning rhythm, and gas resistance at 409 kΩ is near Hive #1's all-time average of 393 kΩ — everything stable.
🌅 Diurnal Cycle PatternsHive #1 shows a 5.0°F (2.8°C) daily temperature oscillation (88.6–93.6°F / 31.4–34.2°C) — its peak reaching the bottom of the ideal brood band — with a clear vibration fanning rhythm (15/15 days, baseline ~15.8 mG rising to ~25.9 mG, avg 1.6×) and the dominant vibration band in the 80–120 Hz fanning zone (−10.5 dB). The sound spectrum shows no strong per-band daily rhythm (max 1.0 dB in any band), which is consistent with a colony whose acoustic energy is broadly distributed rather than concentrated in a single frequency range — a stable, organized spectral fingerprint. The gas heater-scan shows a robust daily rhythm across all 10 steps (strongest at 150°C, +35% swing), with the 150°C step carrying the highest daily modulation — suggesting the VOC mix in Hive #1 is rich in mid-volatility compounds (propolis terpenes, brood pheromones) that cycle with daily fanning activity.
🔬 Correlations & Discoveriestemperature vs humidity (14d) | r = +0.94The exceptionally strong deseasonalized temperature-humidity coupling in Hive #1 (r=+0.94, the highest in the apiary) reflects tight metabolic co-regulation: brood heating and larval respiration generate water vapor in near-lockstep, and the partial correlation (r=+0.44 controlling for outdoor temp) confirms this is a genuine colony-internal physiology coupling, not a shared ambient response — a hallmark of a densely brooded, well-populated colony actively managing both heat and moisture.📚 Reference: Human et al. 2006, Ellis et al. 2008, Stabentheiner et al. 2010humidity vs gas_resistance (14d) | r = +0.54The positive humidity-gas resistance coupling in Hive #1 (r=+0.54) reflects a well-understood MOX sensor physics effect: higher in-hive humidity reduces the sensor's sensitivity to VOCs by competing for adsorption sites on the SnO2 layer, so when humidity rises (with brood heating), resistance rises slightly even if VOC concentration is unchanged — a sensor-physics artifact of active hygroregulation, not a change in colony chemistry.📚 Reference: Burgues & Marco 2018, Maisonnasse et al. 2010, Frizzera et al. 2020▹ Action: On your next routine visit within 5–7 days, take a look at the brood frames in Hive #1 — nineteen acoustically stable reports and a steady warming arc are strongly reassuring, and a visual confirmation of the queen laying solidly will complete the picture. -
Hive #3 healthy Score: 93/100📋 Overall Health
Your Hive #3 remains the apiary's standout performer heading into August — brood temperature locked at 93.6°F (34.2°C) avg with an exceptional 2.3°F (1.3°C) daily oscillation (92.8–95.1°F / 33.8–35.1°C), exactly matching the all-time average of 93.6°F (34.2°C) and held firmly in the ideal 93–97°F (34–36°C) zone with textbook stability; all 10 sound bands match their all-time baseline within ±0.3 dB (avg −16.3 dBFS vs. all-time −16.3 dBFS — a perfect match), and humidity averaged 49.6% — the most stable and optimal in the apiary, approaching the healthy 50–70% range. Vibration at 20.3 mG avg with kurtosis 2.6 is smooth and near the all-time average of 21.0 mG; gas resistance at 95 kΩ remains in sustained low-resistance territory (all-time avg 136 kΩ), but the heater-scan shape continues its evolution with low-temperature steps (100°C, 150°C, 200°C) rising +12–20% — the same gradual easing fingerprint noted last report, suggesting the honey-curing VOC load is continuing to wind down.
🌅 Diurnal Cycle PatternsHive #3 shows a compressed 2.3°F (1.3°C) daily temperature oscillation — the tightest brood clamping in the apiary — with a clear vibration fanning rhythm (14/15 days, baseline ~19.5 mG rising to ~32.2 mG peaks, avg 1.6×) and the dominant vibration band in the 80–120 Hz fanning zone (−8.6 dB). A mid-window vibration band shift (dominant daily rhythm moving from 50–80 Hz to 5–20 Hz) is worth watching — it may reflect a subtle change in substrate resonance or colony activity pattern but is not corroborated by any acoustic or thermal anomaly. The gas heater-scan daily rhythm has shifted its dominant step from 100°C to 250°C, and the 320°C and 150°C steps are both weakening in their daily swing (+19% → +4% and +24% → +9% respectively) — consistent with the mid-volatility VOC component of the honey-curing cycle diminishing while the heavier volatiles persist, exactly the progressive easing pattern observed over the past two weeks.
🔬 Correlations & Discoveriestemperature vs humidity (14d) | r = +0.76The strong deseasonalized temperature-humidity coupling in Hive #3 (r=+0.76, partial r=+0.47 controlling for outdoor temp) is a physiological signature of active brood-zone hygroregulation — as the colony's metabolic output sustains the tightest brood temperature in the apiary, larval respiration and evaporative cooling generate proportional water vapor, and the partial correlation confirms this is hive-specific colony physiology rather than ambient tracking.📚 Reference: Human et al. 2006, Ellis et al. 2008, Eouzan et al. 2019temperature vs gas_resistance (14d) | r = +0.45The positive temperature-gas resistance coupling in Hive #3 (r=+0.45) mirrors the same ventilation-driven mechanism seen in Hive #2: daily fanning surges that regulate the tight brood temperature also flush honey-curing and brood-pheromone volatiles, briefly raising MOX resistance — while the sustained low absolute baseline (95 kΩ vs. 136 kΩ all-time avg) reflects the standing honey-ripening VOC load that has been present since mid-July and is now gradually easing as captured in the heater-scan shape evolution.📚 Reference: Frizzera et al. 2020, Seeley 1974, Maisonnasse et al. 2010▹ Action: On your next routine visit within 5–7 days, note the fill level and capping progress of supers in Hive #3 — the continued heater-scan shape evolution (low-temperature steps rising, mid-step rhythm weakening) alongside exceptional brood clamping points to a honey-curing cycle that may be nearing completion, and a super observation will anchor this multi-week sensor trend to your season records.
