How do I adjust my crested gecko’s care for winter?
Keep your crested gecko between 72–80°F (22–27°C) year‑round and maintain 50–70% humidity to avoid stress. In winter you’ll drop the temperature to the low‑70s and shorten misting to keep the enclosure from drying out.
summer heat limits and safety
During the hottest months aim for a maximum of 80°F (27°C) inside the enclosure; anything above 85°F (29°C) can cause loss of appetite and rapid dehydration. I place the tank on a shaded side of the room and use a 10‑watt LED fixture instead of a basking bulb, which keeps the ambient temperature steady without spikes. A digital thermometer on the back wall lets me spot a rise of 2°F (1°C) within minutes, so I adjust the room’s AC accordingly.
Humidity should stay between 60–70% in midsummer, dropping to about 50% after each mist. I mist with a 2‑oz (60‑ml) spray bottle every 12hours, then wipe excess water from the foliage with a paper towel. If the hygrometer reads above 70%, I open a window for 10minutes or run a small oscillating fan on low for 5minutes to circulate dry air.
- Set thermostat to 78°F (25.5°C) max.
- Mist 2oz (60ml) water twice daily.
- Vent enclosure 10min if humidity >70%.
winter temperature, daylight, and activity
In December and January I lower the enclosure temperature to 72–75°F (22–24°C); a 40‑watt ceramic heat emitter on a timer for 4hours at night prevents the drop below 70°F (21°C). I check the temperature at three points—floor, mid‑level, and top branch—to ensure a uniform gradient of no more than 3°F (2°C) between them.
Daylight hours shrink to 10–11hours, so I run a 6500K LED on a 10‑hour on/14‑hour off cycle. The reduced light mimics natural winter and usually slows feeding to 2–3 insects per week instead of daily. I also cut the fruit mix to 1tbsp (15g) every other day, watching for weight loss of more than 5% as a warning sign.
- Use 40W ceramic heater for 4h nightly.
- Run LED 10h/day, 14h off.
- Feed 2–3 insects/week, 1tbsp fruit mix/2days.
seasonal hazards people underestimate
Holiday poinsettia leaves and mistletoe contain oxalates that can irritate a gecko’s mouth; I keep all decorations at least 12inches (30cm) away from the enclosure. Even scented candles can release volatile compounds that lower humidity, so I never light them near the tank.
Guests often think a crested gecko is a pet they can hold; a sudden grip for more than 30seconds can cause stress‑induced shedding issues. Fireworks produce loud bangs that raise the enclosure’s temperature by 2–3°F (1–2°C) due to rapid air movement, so I cover the tank with a breathable cloth for the night of a display.
- Remove toxic plants >12in away.
- Limit handling to <30seconds per session.
- Cover tank during fireworks.
seasonal checklist
Every two weeks I calibrate the thermometer and hygrometer with a known‑temperature water bath and a saturated‑salt solution, respectively. I also rotate the branch perches by 90° to prevent mold buildup in the same spot.
Before any holiday travel I pack 4oz (120ml) of pre‑misted substrate in a sealed bag to maintain humidity if the enclosure sits unattended for up to 48hours. I test the enclosure’s seal by placing a piece of paper on the lid; if it stays dry after 30minutes, the seal is good.
- Calibrate devices bi‑weekly.
- Rotate perches each 2weeks.
- Prepare 4oz misted substrate for travel.
- Check lid seal with paper test.
daylight & photoperiod adjustments
From May to August I keep the light on for 12hours, matching the longest day length; a simple plug‑in timer handles the switch without manual intervention. In September I reduce the on‑time by 30minutes each week until I reach 10hours in December.
I monitor the gecko’s activity by noting the time it climbs after the lights come on; if it’s less than 5minutes, I may have set the light too early or the temperature too low. Adjusting the timer by 15minutes forward usually restores the normal burst of climbing.
- 12h light May–Aug, reduce 30min weekly Sep–Dec.
- Observe climb response within 5min of light on.

Related questions
Do I need a heat lamp for my crested gecko in winter?
No. A 40‑watt ceramic heat emitter on a 4‑hour night timer keeps the enclosure at 72–75°F (22–24°C), which is sufficient for winter.
How often should I mist the enclosure in summer?
Mist with 2oz (60ml) of water twice daily, roughly every 12hours, and wipe excess after each mist to keep humidity at 60–70%.
What temperature drop is safe when the room gets colder?
A drop of up to 5°F (3°C) is fine as long as the enclosure never falls below 70°F (21°C); use a thermostat to avoid larger swings.
