Traveller notes on Tioman in August
Other months in Tioman
Tioman's forum consistently places September within the South-West Monsoon window that's generally considered favorable here, since most of the moisture has already dropped over Sumatra before reaching the island - one traveler who'd just returned described it as hot, sunny and windy rather than wet. That said, this is still a genuinely rainy tropical island even in its better months, with regular showers part of daily life; the real distinction posters draw is against October through December, when rain becomes far more frequent and the seas noticeably rougher. September is the calmer side of that comparison, not a dry month outright.
Forum posters are direct that November through March is the northeast monsoon season on Tioman, generally advising against a visit during that stretch given the real chance of heavy rain and choppy seas that this East Coast Malaysian island shares with nearby Redang and the Perhentians. Posters do flag genuine improvement by late March specifically, since the monsoon typically wraps up just before Easter - meaning conditions by the back half of the month should already be trending toward the hot, humid, drier pattern that runs from roughly mid-March through October. Posters generally recommend timing a March visit toward the later half of the month rather than earlier, to land past the worst of the lingering monsoon influence.
