The region around Andasibe with the associated forests of Mantadia, Mitsinjo and Analamazaotra lie in the eastern highlands of Madagascar at altitudes between 900 and 1250 m above sea level. During the day, the temperature may sometimes exceed 25°C, but the thermometer rarely climbs above 30°C, or only in sunspots. At night, temperatures plummet, especially during the dry season. 10° to 15° degrees are the rule.
Humidity in the rainforests around Andasibe is high all year round. During the rainy season it rains extensively every day, sometimes the rain lasts for days. But the dry season is not massively different either, except that it has slightly cooler temperatures overall and reaches lower temperatures at night. It still rains at least every other day. Rain, high humidity and a drop in temperature at night are therefore the central points of Andasibe's climate. In 2023, we measured relative humidity with data loggers on different days in Andasibe in the rainy season, the data can be found below.

We have measured UVB data with a Solarmeter 6.5 in spring (March, April) at the peak of activity of chameleons in Madagascar. We always measured the values that a chameleon could maximally reach in its habitat.
Between 21 March 2018 and 05 February 2019, we measured ground temperatures in the rainforest of Andasibe and surrounding areas (Analamazaotra, Andasibe, V.O.I.M.M.A. and Mitsinjo) about every other day - the table is the result of these measurements. Only in December no measurements were taken. detailed review can be found here. In total, we took 418 soil temperature measurements and measured an estimated 70 different locations in Andasibe and the surrounding area at a depth of 20 cm.
