Kuala Lumpur’s climate is shaped by its equatorial location, resulting in little temperature variation and abundant rainfall. Average daily highs range from 31–33°C and lows from 22–24°C, with humidity typically between 75–85%. The city experiences two main monsoon seasons: the Southwest Monsoon (May–September) brings relatively drier, sunnier weather, while the Northeast Monsoon (October–March) brings heavier rainfall, peaking in November and December. Even during the driest months, rain is common, but usually falls as short, intense afternoon or evening showers. Sunshine averages 6–8 hours per day, but clouds and haze are frequent, especially in the wet season. Winds are generally light (4–8 km/h), but can pick up during thunderstorms. Daylight lasts about 12 hours year-round, with sunrise around 7:00 and sunset near 19:20. The UV index is very high, often reaching 11, so sun protection is essential.
Rainfall is a defining feature, with annual totals around 2,400 mm and over 200 rainy days per year. November is the wettest month, averaging 290 mm of rain and up to 25 rainy days, while June and July are the driest, with about 120–140 mm and 10–15 rainy days. Despite frequent rain, showers are usually brief and rarely disrupt travel plans for long. The city’s lush greenery, vibrant gardens, and cooling rain showers are part of its tropical charm. Occasionally, smoke haze from regional agricultural fires can affect air quality, especially in August and September. Snow is unknown in Kuala Lumpur.
