As Singapore is only 136km north of the Equator, the weather is relatively unchanging throughout much of the year. For some, a constant tropical climate is a bonus – for others, it can induce a form of claustrophobia and the complaint is sometimes heard that there are no seasons in Singapore.
Daytime temperatures will typically range from between 28°C to 33°C all year round, but this is usually accompanied by a pretty high degree of humidity (the daily average is 84%, although on a ‘dry’ day it can drop as low as 60%). The hottest time of day is usually during the early afternoon (the average temperature being about 30°C), but even at its coolest (generally just before dawn) the average temperature is still around 24°C.
All of this means that Singapore is hot more or less the whole time. If Singapore does have seasons, it is usually even hotter during July and August (although schools are on holiday at this time, which is at least some small consolation), while the coolest (and wettest) months of the year are November to January, although most expatriates would still consider it be pretty warm and humid at this time. Most people soon get used to always having sunblock, a hat, a rain jacket and plenty of water with them whenever they go out.
However, evenings in Singapore are generally a little cooler and it can be extremely pleasant out of doors at nighttime. This leads to lots of al fresco eating and drinking opportunities for adults, and much more time to play for children, and so for many expatriates the climate can lead to a new and exciting lifestyle change.
The weather in Singapore also means that it experiences twelve hours of daylight each and every day, so there is generally no need to get up in the morning in the dark, while most people will also return home from work in daylight. For many expatriates, this marks a welcome change to their normal lifestyle.
The greatest climactic variation is in rainfall, as there are two monsoon seasons in Singapore. You can expect to get used to carrying an umbrella with you for much of the year (useful for shade from the sun, too) and you will quickly become adept at knowing how to spot when rain is coming in time to be able to nip indoors or under cover.
The Northeast Monsoon begins at the start of November and lasts until mid-March. There is heavy rainfall between November and January (the monthly average is 260mm) and it will rain on most days, often accompanied by thunder and lightning. On some days, there will be showers that last for some time, while at other times there are short, heavy bursts of rain which then disappear quite quickly. Rain will usually occur early in the morning or in the afternoon. It is, however, rarely windy. The Southwest Monsoon occurs between June and September. At this time, temperatures can be at their highest although this is also the ‘driest’ time of the year (the average monthly rainfall is 170mm).
