Pogoda Perhentian Islands (Perhentian) — styczeń

Regulars are specific this marks the end of the monsoon season here, considerably more severe than elsewhere in the region but genuinely wrapped up by this point, peak season now underway with occasional 10-to-20-minute showers rather than a daily soak. Our row backs that hot, genuinely wet read, 30.2C reading as a scorching 37C, over 25.7C nights feeling 30C, with a substantial 109.9mm of rain across 14.1 days and humidity at 82 percent. Regulars are honest Malaysia's weather generally stays a bit unpredictable, calm seas the norm but genuinely capable of varying from year to year. This remains squarely within the broader April-through-September window regulars call the best time to visit. The sea sits at a bath-warm 31C. The record: 11 hours of sun, an 18.6 kph wind and AQI 48.

Regulars call this good diving and snorkeling weather overall, only the occasional storm interrupting otherwise reliable conditions, with visibility and water temperature just under 30C making it a genuinely strong month for time in the water. Our row backs a wetter reality than that framing implies, 114.1mm of rain across 17.1 days, alongside real heat, 30.3C reading as a hot 37C at 84 percent humidity, over 25.8C nights. Regulars are consistent this marks the start of the islands' peak season, running through August, so the trade for the reliable conditions is busier beaches and accommodation booking up further ahead. The sea holds a warm 31.2C. The record: 10.4 hours of sun, a 14.9 kph wind and AQI 48.

Regulars here draw a line between two wet things that get confused. The north-east monsoon runs November to March and closes the islands; what August gets is the thunderstorm season, which they are clear is a different animal - it starts late in the evening, it is not continuous, and some days it does not rain at all. Diving and snorkelling carry on through it, and the visibility is often at its best right before a storm, because the hours ahead of one are scorching and bright and the water goes clear. That is the reading to take from our 114.1mm across 18.2 days. August is peak season and they call it the best timing to come. The record: 30.1C feeling like 38C, a 31C sea and 10.5 hours of sun.

Our row for February looks perfectly inviting - 27.6C, a 28.2C sea - and regulars will tell you that is not the question. This coast is in the north-east monsoon from November to March, the sea is rough, and most resorts and boat services shut for it. Some reopen during February, the monsoon can be over by mid-month, but it varies year to year and plenty of places do not open until the end of March. Boats simply will not cross in bad weather. Their advice to anyone travelling a long way is to follow the official season, which starts in March, rather than gamble a fortnight on an early reopening. Our 116.7mm across 13.2 days and a 23.3 kph wind are the monsoon's tail. The record: 24C nights, humidity 83 percent and 10.5 hours of sun.
