Climate:
In Malaysia the climate is equatorial, ie hot, humid and rainy throughout the year. Temperatures are high and stable, ranging between 25°C and 33°C.
Rainfall is abundant and frequent throughout the year, in fact, it is difficult to find a month when it is lower than 100mm; however, it is possible to find periods when it is not too high, although they are not the same everywhere.
The rains are caused by the monsoon regime. As Malaysia is near the Equator and surrounded by the sea, there is no real dry season. In addition, the rains, as is generally the case in tropical countries, are quite erratic from year to year.
However, the monsoons make precipitation more abundant and frequent in the areas directly exposed to these winds: between mid-October and January, the northeast monsoon prevails, affecting especially the east coast of Peninsular Malaysia and the north-east coast of Borneo, while between June and September, it's the period of the southwest monsoon, which, in Malaysia, usually produces weaker effects.
It should be noted, however, that the tropical rains occur mainly in the form of intense downpours or thunderstorms, usually in the afternoon, so there's no shortage of sunshine, at least in the morning, when the weather conditions are generally good.
In Penang, January and February are the best months. In December and March, rainfall is around 150mm per month, and it's even higher from June to August, when it's around 200mm per month.
