Watch the measured night floor
Outdoor lows can increase heating demand in some homes, but insulation and indoor climate control can change the result. Record overnight room, warm-side, and cool-side values before adding heat.

Seasonal narrative
The coldest average daily minimum occurs in July (42.7°F); the warmest average daily maximum occurs in February (103.7°F).
Outdoor lows can increase heating demand in some homes, but insulation and indoor climate control can change the result. Record overnight room, warm-side, and cool-side values before adding heat.
During February, check that the enclosure still provides the species-specific cool zone. Adjust the room or ventilation only from measured values.
September has the lowest contextual outdoor humidity in this record. Indoor ventilation, substrate, heating, and household HVAC can produce a very different reading.
Equipment decision workflow
Measure daytime and overnight room temperature through the season you are planning for.
Note internal dimensions, material, ventilation area, target night floor, and heat-source distance.
Select a thermostat type compatible with the heat source; follow the manufacturer’s placement and load requirements.
Test an empty setup, then confirm warm-side, basking-surface, cool-side, and night readings with suitable instruments.

Source and limitations
NASA POWER climatology values are gridded outdoor means (MERRA-2 meteorology), not indoor enclosure conditions. Relative humidity is outdoor context only; measure the habitat directly. High/low card values are labeled as climatological maximum/minimum until a daily-data-derived average-daily pipeline is proven executable.
