Traveller notes on Johor Bahru in December
Other months in Johor Bahru
Forum posters describe Johor Bahru as very hot and humid in August, with typical daytime temperatures around 32C and humidity that can climb toward 90%. Posters consistently note that Malaysia's proximity to the equator means there's no real seasonal variation in temperature year-round, staying around 32C with generally high humidity regardless of month. Posters describe occasional nighttime thunderstorms as a real feature of an August or September visit to the west coast, but are consistent that being in a wetter stretch doesn't mean daily rain - just a somewhat higher chance of it on any given day. Posters generally rate August as hot and humid but entirely typical for Johor Bahru, with no particular weather advantage or disadvantage compared to most other months.
Locals on the forum explain that February/March is the tail end of the North-East monsoon, and Johor Bahru, sitting at the southern tip of the peninsula, hardly catches the full brunt of it. The typical day: sunny for stretches, some cloud, maybe a bit of rain, or at worst a two-hour local thunderstorm - rarely an all-day washout. The overall read from regulars is that the rain is localized and brief enough not to really disrupt a visit.
