Best Time to Visit Singapore: Weather by Month and When to Avoid

The short answer: Singapore sits just above the equator, so it’s hot and humid year-round — there’s no cool season to wait for. The real question isn’t temperature, it’s rain: February and March bring the fewest rainy days and the lowest overall rainfall, while November and December are the wettest months of the year. If you’re flexible, build your trip around the calendar below rather than the weather app the week before you fly.

When Is the Best Time to Visit Singapore?

February and March are Singapore’s most reliable months to visit. They have the fewest rainy days of the year — February averages just 13 — and noticeably lower rainfall than the rest of the calendar. Temperatures don’t swing much by season here, so “best” in Singapore mostly means “driest,” not “coolest.”

What’s Singapore’s Weather Like Month by Month?

Month	Avg. High / Low	Rainfall	Rainy Days
January	30°C / 23°C	238 mm	18
February	31°C / 24°C	165 mm	13
March	31°C / 24°C	177 mm	17
April	31°C / 24°C	166 mm	20
May	31°C / 25°C	171 mm	19
June	31°C / 24°C	163 mm	19
July	31°C / 24°C	150 mm	19
August	31°C / 24°C	171 mm	20
September	31°C / 24°C	163 mm	18
October	31°C / 24°C	191 mm	21
November	30°C / 24°C	250 mm	25
December	29°C / 23°C	269 mm	25

Two patterns stand out: July has the lowest rainfall total (150 mm) but still around 19 rainy days, so showers tend to be short and scattered rather than all-day events. November and December, by contrast, bring both heavy rainfall and the most rainy days of the year.

Does Singapore Have Monsoon Seasons?

Yes, two. The Northeast Monsoon runs roughly December through early March and brings Singapore’s heaviest, most consistent rain. The Southwest Monsoon runs roughly June through September and tends to bring shorter afternoon thunderstorms rather than prolonged downpours. Broadly, September through January is the wetter stretch of the year and February through August the drier one — though “dry” in Singapore still means regular afternoon showers.

When Should You Avoid Visiting Singapore?

If avoiding rain is your top priority, November and December are the months to be most cautious about — they combine the year’s highest rainfall with the most rainy days. Summer months (June through August) are also worth flagging for a different reason: they’re peak tourist season in Singapore, which means higher hotel rates and tighter availability, independent of the weather.

What About the Seasonal Haze?

Between roughly May and September, smoke from agricultural burning on nearby Sumatra can drift into Singapore and affect air quality, particularly for travelers with respiratory conditions. Haze severity varies significantly year to year and isn’t guaranteed — some years it’s a non-issue — but if you have respiratory sensitivities and are traveling in this window, it’s worth checking Singapore’s National Environment Agency air quality readings in the days before your trip rather than assuming clear skies.
