Holidays to the Cameron Highlands are very popular during the March to May hot-season school holidays and so can get very busy at this time.
With hills in every direction, the weather in the Cameron Highlands is unpredictable, and you can expect rainstorms even in the dry season. It makes sense to avoid the area during the monsoon itself (Nov–Jan), and at major holiday times if you want to avoid the crowds. Given the 1000m-plus altitude, temperatures drop dramatically at night – whatever the season – so you’ll need warm clothes, as well as waterproofs.The temperate climate remains constant year-round, but the coolest part of the year is December through February, when temperatures can drop as low as 10 C (50 F).
