Traveller notes on Ko Lipe in May

Other months in Ko Lipe

Regulars are honest experiences here vary even within the same peak window, one visitor calling the weather absolutely perfect from December 11th onward aside from a couple of rainy morning hours, another arriving just two days later reporting mostly cloudy skies with barely four hours of real sun the whole stay. Our row backs that hot, genuinely wet read, 28.6C reading as a hot 33C, over 25.9C nights feeling 28C, with a substantial 150.8mm of rain across 14.7 days and a real 25.8 kph wind. Regulars are consistent the best weather window is generally understood to run from mid-December through the end of February, peak season lining up with that same stretch. The sea sits at a bath-warm 29C. The record: 9.2 hours of sun, humidity 78 percent and AQI 40.

Regulars describe genuinely bimodal outcomes here - a whole sunny week is possible, so is a week of mixed weather, but an entire week of solid rain is very unusual even though this sits inside the technical monsoon season. Our row backs the wet reality of that season regardless, a striking 150mm of rain across 19.2 days, alongside real heat, 29.1C reading as a hot 35C at 80 percent humidity, over 26.7C nights. Regulars are candid this isn't the ideal month for weather specifically - seas can run rough enough to affect inter-island ferries and boat trips - but note accommodation runs noticeably cheaper as a direct trade-off. The sea holds a warm 30.8C. The record: 9.7 hours of sun, a 17.6 kph wind and AQI 44.

April is where the Andaman year changes: the south-west monsoon runs May to October, and by late April the rains are just arriving. Our row nearly triples March's rainfall to 153.8mm across 22.7 precipitation days. Regulars describe the pattern rather than the total - thunder showers mostly in the late afternoon and evening, plenty of sunshine in between, and very rarely a full day of rain - so April still functions. Practically, the Langkawi ferries run to the 31st of May and most resorts and Walking Street shops stay open, so nothing shuts yet. Heat is the other cost: 29.6C over a 26.8C night reads as 36C and 31C, and the sea is 30.6C, the warmest in this collection. The record: humidity 80 percent, 10.4 hours of sun and AQI 50.

March closes the good run on Ko Lipe - regulars say the weather is reliable from early January to the end of March, normally sunny with a calm sea and excellent snorkelling, and they name January and March as the two best months. Late March is also the tail of high season: still busy, ferries plentiful, and the beaches lined almost end to end with longtail boats. Their end-of-March figures of 33C by day and 26C at night sit above our 29.9C monthly average because the month warms as it goes; the 26.7C night reading as 30C is the part people underestimate. With the sea at 29.6C there is nothing cool to get into. April and May are quieter. The record: 55.4mm across 11.8 precipitation days, humidity 74 percent, 10.8 hours of sun and a 21.7 kph wind.

What's on in Ko Lipe in May

Recurring seasonal events, natural spectacles, closures and holidays — curated and sourced.

  • Season

    Southwest monsoon

    15 May – 15 Oct · usuallyRisk

    Swell on the west-facing beaches and days when nothing crosses from the mainland at all. The handful of places that stay open charge a third of the high-season rate.

  • Closure

    Tarutao marine park closed

    16 May – 15 Oct

    The park shuts its islands for the monsoon every year. Ko Lipe itself is exempt and stays open, but the snorkelling stops, the speedboats thin to a weather-dependent service, and most resorts close. Source ↗

  • Season

    High season, flat Andaman

    1 Nov – 15 May · usuallyDry seasonCrowded

    Speedboats run daily from Pak Bara and Langkawi, the reef off Sunrise Beach is clear, and Walking Street is busy every night. Everything on the island is open, which is not true the rest of the year.
