As of July 24, 2026, your four-hive apiary is navigating peak July heat in strong overall shape — Hive #3 and Hive #2 continue exceptional brood-core clamping, Hive #1 remains acoustically pristine for a ninth consecutive report, and Iris carries the apiary's one open question: a persistent broad-spectrum acoustic elevation above her own baseline that continues to warrant a brood-and-queen verification this week.
All four hives show clean 15/15 or 14/15 daily fanning-vibration rhythms and stable 14-day acoustic trends, confirming apiary-wide circadian health; the contrast between Hive #2 and Hive #3's ultra-compressed ±0.9°F / ±0.5°C diurnal brood oscillations versus Iris and Hive #1's wider ±2.6°F / ±1.4°C arcs reflects genetic and colony-size differences in thermoregulatory precision, consistent with Jones et al. 2004 on patriline diversity and temperature buffering.
All four hives show repeatable daily fanning-vibration peaks and stable acoustic energy across the 14-day window; Hive #2 and Hive #3 lead in brood-core thermal clamping with sub-1°C oscillations, while Iris and Hive #1 ride wider but structurally normal arcs driven by peak-season ambient heat rather than any regulatory failure.

Iris warning Score: 57/100📋 Overall Health
Your Iris hive remains fully populated and acoustically vigorous — sound averaged −10.1 dBFS (all-time avg −10.7 dBFS, only +0.6 dB from baseline), confirming an intact worker population — but the persistent broad-spectrum acoustic elevation continues for another consecutive report: 100–150 Hz +7.2 dB, 1500–3600 Hz +7.1 dB, 150–200 Hz +5.7 dB, and 800–1500 Hz +4.2 dB all remain elevated above her own all-time baseline, temperature averaged 90.7°F (32.6°C) with a +4.7°F (+2.6°C) daily oscillation, humidity averaged 48.3% (range 46.5–50.0%, just below the 50–70% optimal zone but consistent with the apiary's dry July ambient), and vibration is stable at 17.9 mG avg with kurtosis 4.4 (below the >5.0 impulsive threshold). A brood-and-queen check this week remains the priority open question for Iris.
🌅 Diurnal Cycle PatternsIris shows a clear daily temperature arc of +4.7°F (+2.6°C) driven by peak-season ambient heat — the deseasonalized analytics confirm this is pure thermal-mass buffering (deconfounded r=+0.05 vs outdoor temp), not a regulatory failure; vibration shows 15/15 daily fanning peaks (baseline ~16.8 mG rising to ~35.0 mG, avg 2.1×) and the gas heater-scan carries a strong 24-h rhythm (strongest at 100°C step, +24% swing, 7/10 bands cycling), consistent with fanning-driven VOC circulation across the day. The broad-spectrum acoustic elevation (strongest daily rhythm at 200–260 Hz, 6.8 dB) is structurally stable across the 14-day window with no further escalation, but its persistence across both low (100–200 Hz) and high (800–3600 Hz) bands simultaneously remains the key open signal to resolve physically.
🔬 Correlations & Discoveriesvibration vs VibrationKurtosis (14d) | r = +0.5The genuine deconfounded coupling between vibration RMS and kurtosis (r=+0.50, p=1.3e-49) in Iris indicates that her higher-amplitude vibration episodes are also impulsive in character — consistent with bursts of intense fanning or defensive activity rather than smooth metabolic background hum; with kurtosis averaging 4.4 (approaching but below the >5.0 impact threshold), this pattern aligns with a large, active colony generating periodic high-energy behavioral events, which is also consistent with the sustained broadband acoustic elevation observed across multiple reports.📚 Reference: Ramsey et al. 2020, Hrncir et al. 2011⚠️ Issue: Broad-spectrum acoustic elevation persists above all-time baseline for multiple consecutive reports: 100–150 Hz +7.2 dB, 1500–3600 Hz +7.1 dB, 150–200 Hz +5.7 dB, 800–1500 Hz +4.2 dB — brood and queen verification recommended this week.⚠️ Issue: Humidity avg 48.3% (low 46.5%) — just below the 50–70% brood-optimal range; consistent with dry July ambient but worth noting if lows approach 45% on consecutive days.▹ Action: Priority this week: perform a brood-and-queen check on Iris — confirm fresh eggs, solid brood pattern, and queen presence; the persistent multi-band broadband acoustic elevation spanning both low and high frequencies across multiple consecutive reports is the apiary's primary open question and a physical look will resolve it.▹ Action: While inspecting, note whether the colony feels exceptionally populous or defensive — both are consistent with the sustained elevated broadband acoustic energy profile seen in Iris. -
Hive #1 healthy Score: 78/100📋 Overall Health
Your Hive #1 remains acoustically pristine for a ninth consecutive report — all 10 sound bands within ±0.1 dB of their all-time baseline (sound averaging −16.4 dBFS vs. all-time avg −16.4 dBFS, a perfect match), confirming the adult bee population is fully intact and active; temperature averaged 89.9°F (32.2°C) (all-time avg 89.1°F / 31.7°C, +0.8°F / +0.4°C above baseline) with a +4.3°F (+2.4°C) daily oscillation, humidity averaged 43.2% — consistent with the apiary's dry July ambient (44.7% RH outdoor), and vibration is stable at 16.6 mG avg with kurtosis 3.2 (normal). Watch for continued brood temperature stability as the apiary moves through late July.
🌅 Diurnal Cycle PatternsHive #1 shows a clean +4.3°F (+2.4°C) daily temperature arc — the deseasonalized analytics confirm this is ambient buffering only (deconfounded r=+0.01 vs outdoor humidity), with outdoor leading in-hive by ~280 min, a healthy thermal-mass signature; vibration shows 15/15 daily fanning peaks (baseline ~15.9 mG rising to ~24.3 mG, avg 1.5×) and the gas heater-scan cycles across all 10 bands (strongest at 100°C, +35% swing, with the dominant rhythm band shifting 100°C → 150°C in the second half — a minor shape evolution worth watching but unaccompanied by any temperature or acoustic change). Sound shows no strong per-band daily rhythm (max 0.9 dB at 600–800 Hz), consistent with a quiet but well-populated colony whose acoustic signature is structurally locked to its own fingerprint.
🔬 Correlations & Discoveriestemperature vs gas_resistance (14d) | r = -0.77The strong deconfounded inverse coupling between in-hive temperature and gas resistance (r=−0.77, partial r=−0.72 controlling for outdoor temp) reflects the well-established MOX sensor physics: as in-hive temperature rises during peak foraging, fanning intensifies and circulates brood pheromones (E-β-ocimene), propolis terpenes, and honey-ripening volatiles — all reducing gases that lower MOX resistance; this is normal healthy-colony metabolic chemistry, not a stress signal, especially with acoustics perfectly stable across all 10 bands.📚 Reference: Seeley 1985, Burgues & Marco 2018, Maisonnasse et al. 2010▹ Action: On your next routine visit, confirm fresh eggs and solid brood pattern in Hive #1 — the perfectly stable acoustics across all 10 bands for nine consecutive reports are strongly reassuring, and confirming brood activity will round out the picture heading into late July. -
Hive #2 warning Score: 68/100📋 Overall Health
Your Hive #2 continues outstanding brood thermoregulation — temperature locked at 95.0°F (35.0°C) avg (all-time avg 94.6°F / 34.8°C, +0.4°F / +0.2°C above baseline, firmly in the ideal 93–97°F / 34–36°C zone) with only ±1.6°F (±0.9°C) daily oscillation; humidity averaged 50.9% (range 49.3–52.5%), solidly within the 50–70% optimal zone, and vibration at 14.4 mG avg with kurtosis 3.2 (calm, normal). The persistent low-frequency spectral shift (150–200 Hz +7.4 dB, 100–150 Hz +6.1 dB) combined with modest overall acoustic softening of −1.0 dBFS from baseline continues, with the low-frequency bands trending slightly upward in the second half of the day (+1.2–1.3 dB) adding a mild new nuance — a brood-and-queen check this week remains warranted to confirm the population trend.
🌅 Diurnal Cycle PatternsHive #2 shows an ultra-compressed ±1.6°F (±0.9°C) daily temperature arc — the tightest in the apiary — confirming exceptional brood-core stenothermy; vibration shows 15/15 daily fanning peaks (baseline ~12.2 mG rising to ~48.9 mG, avg 4.0×, the highest fanning amplitude ratio in the apiary) and the gas heater-scan shows a striking diurnal swing (strongest at 150°C, +100% swing, dominant rhythm band shifting 200°C → 100°C in the second half, with 100–200°C steps down 49–57% over the window) — consistent with intensifying honey-ripening or brood-pheromone VOC activity being detected at lower plate temperatures. Sound shows 6/10 bands cycling with the dominant rhythm band shifting 100–150 Hz → 150–200 Hz, aligning with the low-frequency acoustic elevation that has persisted across multiple reports; the vibration z=+3.1 anomaly from the previous report should be watched across the next 24–48 hours to confirm resolution.
🔬 Correlations & Discoveriestemperature vs humidity (14d) | r = -0.51The genuine deconfounded inverse coupling between in-hive temperature and humidity (r=−0.51) in Hive #2 is classic psychrometric hygroregulation: as the colony heats the brood nest, the same absolute water content registers as lower relative humidity — a healthy thermoregulatory signature, not drying; Hive #2's exceptionally tight ±0.9°C temperature clamping means this humidity-temperature inverse is particularly clean and stable, consistent with a large, well-regulated colony actively managing both heat and moisture in the brood zone.📚 Reference: Human et al. 2006, Ellis et al. 2008, Eouzan et al. 2019⚠️ Issue: Low-frequency acoustic bands remain elevated above all-time baseline: 150–200 Hz +7.4 dB, 100–150 Hz +6.1 dB — with low-frequency bands now trending upward in the second half of the day (+1.2–1.3 dB), a brood-and-queen check this week is warranted to confirm population trend.▹ Action: Plan a brood check this week on Hive #2 — confirm fresh eggs and solid brood pattern; the low-frequency spectral shift and modest overall acoustic softening warrant a physical look even though brood temperature, humidity, and vibration remain fully stable.▹ Action: Note the sustained gas heater-scan step-down (320°C ref 143 kΩ vs. all-time avg 339 kΩ) and the low-temperature step compression (100–200°C steps down 49–57% over the window) in your inspection log — now building a multi-week VOC fingerprint that will be a valuable reference baseline for future comparison. -
Hive #3 healthy Score: 91/100📋 Overall Health
Your Hive #3 continues as the apiary's standout performer — brood temperature locked at 93.9°F (34.4°C) avg (all-time avg 93.4°F / 34.1°C, +0.5°F / +0.3°C above baseline, firmly in the ideal 93–97°F / 34–36°C zone) with an exceptional ±1.3°F (±0.7°C) daily oscillation, and all 10 sound bands within ±0.2 dB of their all-time baseline (sound averaging −16.3 dBFS vs. all-time avg −16.3 dBFS, a perfect match); humidity averaged 51.5% (range 50.1–52.7%) solidly within the optimal zone, vibration at 20.6 mG avg with kurtosis 2.8 (ideal normal), and the four-week gradual warming trend (+1.1°F / +0.6°C) remains consistent with healthy late-July brood expansion. Watch for the sustained gas heater-scan step-down since ~July 17 as the colony continues its July activity peak.
🌅 Diurnal Cycle PatternsHive #3 shows an ultra-compressed ±1.3°F (±0.7°C) daily temperature arc — the best brood-clamping in the apiary — confirmed as purely endogenous by the deseasonalized analytics (deconfounded r=+0.01 vs outdoor humidity); vibration shows 14/15 daily fanning peaks (baseline ~19.7 mG rising to ~34.7 mG, avg 1.7×) with the strongest daily rhythm at 50–80 Hz, consistent with steady colony metabolic baseline fanning. The gas heater-scan cycles across all 10 bands (strongest at 100°C, +30% swing, with the dominant rhythm band shifting 320°C → 350°C in the second half and low-temperature steps rising +13–19%) — the shift toward low-temperature-step dominance since ~July 17 indicates heavier, less-reactive volatiles (consistent with honey ripening or brood pheromone load) are driving the fingerprint change, while temperature and acoustics remain perfectly stable. Sound shows no strong per-band daily rhythm (max 1.0 dB at 600–800 Hz), confirming a colony whose acoustic profile is exceptionally consistent across the day.
🔬 Correlations & Discoveriestemperature vs humidity vs vibration (14d) | r = -0.78Hive #3 shows a three-way genuine coupling: in-hive temperature drives humidity down (r=−0.78, the strongest temp-humidity inverse in the apiary), while humidity and vibration are positively coupled (r=+0.44) — meaning when humidity rises (e.g. during evaporative cooling or nectar curing), fanning vibration increases in tandem, exactly as expected from the documented fanning-trigger physiology where bees fan in response to rising moisture load; this three-channel coherence is a signature of a large, metabolically active colony with well-integrated thermoregulatory and hygroregulatory responses.📚 Reference: Human et al. 2006, Ellis et al. 2008, Nieh & Tautz 2000▹ Action: On your next routine visit within 5–7 days, confirm fresh eggs and solid brood pattern in Hive #3 — the stable 93.9°F (34.4°C) brood temp, perfectly matched acoustics, and optimal 51.5% humidity all indicate a colony at peak July health; no urgent action needed.▹ Action: Note the sustained gas heater-scan step-down since ~July 17 (320°C ref 105 kΩ vs. all-time avg 196 kΩ) in your inspection log — temperature and acoustics are both perfectly stable, making peak-season honey ripening or brood pheromone activity the most likely explanation; documenting it now builds a useful multi-season VOC baseline for future comparison.
