Assumptions & Methodology
- Dataset Coverage: My weather station dataset contains 5,104 observation logs recorded between March 31, 2026, and October 11, 2026, alongside a aggregated weekly summary table spanning 28 complete weeks.
- Metric Definitions: Actual temperature ($\text{Temp_C}$) measures ambient air temperature, while perceived temperature ($\text{Feels_C}$) accounts for humidity heat index and wind chill factors.
Key Takeaways
1. Seasonal Progression Peaks in Mid-Summer with a Multi-Month Span of 41.6°C
- Peak Summer Warmth: July 2026 registered the highest monthly average temperature at 25.19°C, followed closely by August 2026 at 24.38°C and June 2026 at 23.81°C.
- Record Extreme High: The highest temperature logged during the observation period was 39.10°C on July 2, 2026, at 16:05.
- Record Extreme Low: The lowest temperature recorded was -2.50°C on April 9, 2026, at 07:05.
- Warmest Individual Week: As shown in the "Weekly Temperature Summary" chart, the week starting June 29, 2026 logged the highest weekly average at 28.90°C (with a weekly max of 39.10°C and min of 17.30°C).
2. Distinct Perceived Temperature Shifts Driven by Spring Wind Chill vs. Summer Humidity
- Spring Wind Chill Deficit: In April 2026 and May 2026, actual temperatures averaged higher than "feels-like" temperatures due to lower humidity and wind exposure:
- April 2026: Actual Avg = 13.22°C vs. Feels-Like Avg = 10.78°C ($\Delta -2.44\text{°C}$).
- May 2026: Actual Avg = 17.72°C vs. Feels-Like Avg = 16.08°C ($\Delta -1.64\text{°C}$).
- Summer Heat Index Inflation: High humidity during peak summer inverted this trend, making conditions feel noticeably warmer than actual air readings, as illustrated in the "Monthly Actual vs. 'Feels-Like' Average Temperature" chart:
- July 2026: Actual Avg = 25.19°C vs. Feels-Like Avg = 27.42°C ($\Delta +2.23\text{°C}$).
- August 2026: Actual Avg = 24.38°C vs. Feels-Like Avg = 26.91°C ($\Delta +2.53\text{°C}$).
- Autumn Normalization: By September 2026, actual (20.35°C) and perceived (20.76°C) averages converged within $0.41\text{°C}$, before cooling down in October 2026 (Actual Avg 16.15°C, Feels-Like Avg 15.10°C).
3. Predictable 24-Hour Diurnal Cycles Accompanied by High Early-Season Volatility
- Diurnal Min/Max Timing: Based on the "24-Hour Diurnal Temperature Profile" chart, daily temperatures reach their lowest average point at 06:00 (16.02°C) and peak between 15:00 (25.06°C) and 16:00 (24.99°C), creating an average diurnal spread of 9.04°C.
- High Weekly Temperature Volatility: Early summer and spring experienced severe weekly temperature swings (Max $-$ Min):
- Week of June 8, 2026: Range of 27.00°C (Max 36.70°C / Min 9.70°C).
- Week of April 13, 2026: Range of 26.50°C (Max 32.20°C / Min 5.70°C).
- Week of June 1, 2026: Range of 25.80°C (Max 33.50°C / Min 7.70°C).
