Precipitations are rare, with the exception of the months of December and January, where it is sometimes cloudy, rainy and windy. Malapascua has no seasonal monsoon problems: normally from June to October it is hot and humid, while from November to May it is less hot and drier. The water temperature, on the surface, ranges from 27 to 30 degrees, that of the air from January 28 to August 35 (the minimum ever recorded is 24 degrees, at night in January). If you do not tolerate the heat, better prefer the months from December to April, possibly avoiding Christmas-New Year, Chinese New Year and Easter if you do not like the crowd. But if you like the heat, then the summer months from May to November are perfect.
