With the equatorial climate that Malaysia experiences, the weather in Kuala Lumpur is hot and humid all throughout the year. It has two monsoon seasons, namely the Southwest Monsoon from late May to September and the Northeast Monsoon from November to March.
The weather throughout the country is, for the most part, affected by the monsoons and the height above the sea level of a city, suburb or a rural area. There are, however, heavy rains distributed randomly all over the year, and most of them occur in late afternoons and in the evenings. The temperature from month to month varies slightly. It rarely goes down to 20 degree Celsius but it can go as high as 35 degree Celsius especially in the day. The humidity averages at 58 to 66 percent on a monthly basis and about 70 percent on a yearly basis.
The temperature in the highlands is significantly lower than the temperature in Kuala Lumpur. But Kuala Lumpur is likely to have more sunny days than the hilly areas of the country would, and there are lower humidity and rain occurrence in the capital. And because Kuala Lumpur is surrounded by valleys and hills on most sides, it is comparatively cooler than other parts of the country. The mountainous lands also shield Kuala Lumpur from the monsoon winds coming at different times of the year.
But while there is consistently small variation in the temperature across all parts of Malaysia throughout the months of a year, there is a great difference in the amount of rainfall collected every month. The driest time happens around May to September when the monsoon wind blows from the Southwest. November to March, when the monsoon wind is coming from the Northeast, would be the months when heavy rainfall is expected to occur. Generally speaking, this is the wet season of Kuala Lumpur. In addition, it is also around this time that the country is most hit by typhoons and storms, with most of it occurring in November, sometimes as early as October.
So, if you don’t want to get caught in a middle of a raging storm while you’re on a holiday in Kuala Lumpur, it’s best to avoid these months. The month recorded with the driest weather is July, and the month with the highest level of precipitation is March. Heavy rain showers often extend until April as well. Thus, the best time to visit Kuala Lumpur is from May to September, when the weather is roughly stable with only a few occasional and very rarely-occurring rain showers to expect.
In short, the best vacation weather in Kuala Lumpur is defined by the amount of rainfall rather than the temperature and air pressure in the country. And because it is a tropical country first and foremost, you can expect a lot of sunshine on your visit. Definitely, sunny days can raise spirits and cheeriness, thus making Kuala Lumpur an ideal place for vacationers looking for a change of sceneries. With good weather and happy days, Kuala Lumpur might just be the holiday you’re looking for.
