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
What may change at home
The coldest average daily minimum occurs in July (42.7°F); the warmest average daily maximum occurs in February (103.7°F).
Protect the cool side
During February, check that the enclosure still provides the species-specific cool zone. Adjust the room or ventilation only from measured values.
Let the hygrometer decide
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
Choose control from evidence, not a wattage shortcut.
- 01
Record the room
Measure daytime and overnight room temperature through the season you are planning for.
- 02
Describe the enclosure
Note internal dimensions, material, ventilation area, target night floor, and heat-source distance.
- 03
Match the controller
Select a thermostat type compatible with the heat source; follow the manufacturer’s placement and load requirements.
- 04
Commission and verify
Test an empty setup, then confirm warm-side, basking-surface, cool-side, and night readings with suitable instruments.

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.
