Kuala Lumpur is hot, humid and wet in every month, with afternoon thunderstorms the rhythm of daily life and two rainy peaks a year rather than one. The city runs on Malaysia Time, UTC+8, all year, with no daylight saving.
Climate overview
Kuala Lumpur lies in the Klang Valley on the west side of the Malay Peninsula, sheltered by the Titiwangsa Mountains to the east and by Sumatra across the Strait of Malacca to the west. Its climate is tropical rainforest (Köppen Af): hot, humid and wet in every month, with no true dry season.
Average highs range only from 32°C to 34°C, and lows stay at 24°C to 25°C all year. The difference between the "hot" and "cool" months is barely noticeable; what changes is how often it rains.
With about 2,847 mm of rain a year, falling on around 167 days, Kuala Lumpur is one of the wettest major cities in South-East Asia. Unlike many monsoon cities, its rainiest periods are the inter-monsoon months, March to April and October to November, when light winds allow powerful thunderstorms to build over the valley. November is the wettest month, with 356 mm, and June the driest, with 146 mm.
Kuala Lumpur through the seasons
First inter-monsoon (March to April)
The hottest time of the year, with highs around 34°C, and afternoon and evening thunderstorms on many days. April is one of the wettest months, averaging about 302 mm, with rain on around 17 days.
South-west monsoon (May to September)
The relatively drier season, though "dry" is relative: even the driest month, June, still gets 146 mm. Rain falls on around 10 days in June, the fewest of the year. Mornings are often bright, and storms tend to be less frequent. In some years smoke haze from fires in Sumatra and Borneo reduces air quality, typically between July and September.
Second inter-monsoon (October to November)
Rainfall peaks again, with storms on most afternoons: November sees rain on around 20 days. Flash floods can occur in parts of the city during intense downpours.
North-east monsoon (December to February)
Rain is still frequent, but the heaviest monsoon rains fall on Malaysia's east coast rather than in Kuala Lumpur. Highs are slightly lower, around 32°C, and February is one of the drier months of the year, with 193 mm.
What makes Kuala Lumpur's weather distinctive
Thunderstorms are the defining feature. The Klang Valley is one of the most lightning-prone areas in the world. Storms typically form in the afternoon as heat and humidity build, then break with heavy rain, lightning and gusty winds before clearing by evening. A sunny morning is no guarantee of a dry afternoon.
Flash floods are the most common weather hazard, especially in low-lying areas near rivers. The city has invested heavily in flood control, including the SMART Tunnel, which can serve both as a road and as a stormwater channel.
Haze is the third. In years with large fires in neighbouring Indonesia, smoke can drift across the Strait of Malacca and hang over the city for days or weeks, usually in the second half of the south-west monsoon. Our Weather page shows live conditions and the forecast.
Best time to visit Kuala Lumpur
June to August is generally the best time to visit, with the lowest rainfall and the fewest wet days of the year. Rain is possible in any month, though, so plan outdoor activities, such as the Batu Caves or the Perdana Botanical Gardens, for mornings, and keep indoor options, such as malls, museums and galleries, for afternoons.
The wettest stretches, around April and from October to December, are still workable for a city break, since storms rarely last all day. If you are combining Kuala Lumpur with Malaysia's east coast islands, note that they are best avoided during the north-east monsoon, from roughly November to February.
What to pack
- Light, breathable clothing
- A compact umbrella
- A light layer for strong air-conditioning in malls, trains and cinemas
- Modest clothing for mosques and temples, including the Batu Caves
- Sunscreen and insect repellent
- Sandals or quick-drying shoes for sudden downpours
Time in Kuala Lumpur
Kuala Lumpur uses the Asia/Kuala_Lumpur time zone, Malaysia Time, at UTC+8 all year; Malaysia does not observe daylight saving time. Peninsular Malaysia was on UTC+7:30 until 1 January 1982, when it moved forward half an hour to match Sabah and Sarawak on Borneo, so the whole country now shares one clock. The offset is the same as Singapore's and Beijing's, but because the peninsula lies well west of the zone's centre, sunrise and sunset come late by the clock all year. Kuala Lumpur is currently 8 hours ahead of London.
