Masoala's rainforest is located at the coast with broad side to Antongil bay which behaves more like an open sea concerning climate. Accordingly, spring brings cyclones each year. During rainy season, it rains very intensively on a daily base. But also dry season is not really dry but has regular precipitation.
From October to April it is warmer than usual in Masoala, with temperatures reaching over 30°C in sunny spots. At night, temperatures drop only slightly. The rest of the year, from May to September inclusive, it is different: at night, during the dry season, temperatures plummet to 16°C at night, while at night it is still Mediterranean warm. In 2023 we measured relative humidity with data loggers on several days in Masoala during the rainy season, the data can be found below.

We have measured UVB data with a Solarmeter 6.5 in spring (end of March) at the peak of activity of chameleons in Madagascar. We always measured the values that a chameleon could maximally reach in its habitat.
Unfortunately, we have no ground temperatures for Masoala available yet.
