Malaysia experiences tropical weather and it's basically hot and wet the whole year through. The west coast of Peninsular Malaysia experiences a rainy season from September to December and the east coast, from October to February. As for East Malaysia, it collects heavy rain between November and February.
Basically, if you are in any part of Malaysia in the months of November and December, you should expect rain. Seremban is on the West Coast of Malaysia and should experience rain from September onwards. But it has been so hot these past few weeks. I longed for rain and prayed very hard for the weather to change. My prayers were answered. It rained for the past 2 afternoons. The rain cooled the town of Seremban (not sure about the other parts of the country) and I'm sure many of us enjoyed the cool weather. PTL!
