Like mainland Malaysia, Tioman Island has a hot and humid climate, with sunny afternoons and warm evenings but cool nights. Temperatures are usually consistent and the calm weather peppered with occasional showers and storms.
The tourist season peaks between May and August, when the weather generally displays the least rainfall.
The monsoon winds begin to blow from October, bring heavy rain and strong waves till January (surfing season). During this time, ferries run once a day, while only select hotels (usually the larger ones) will open, providing significant discounts off their standard rates.
