Which month is best to visit Singapore?

What is the weather like in Singapore during the best months?

  • February is often cited as the best month due to lower rainfall (105.1 mm) and more sunshine (Meteorological Service Singapore).
  • December and January are cooler but wetter, with December averaging 331.9 mm of rain.
  • April has the highest average temperature (32.4°C).

When is the dry season in Singapore?

Singapore doesn’t have a true dry season, but February tends to be the driest month. The northeast monsoon (November to March) brings the heaviest rains, while the inter-monsoon periods (April/May and October/November) see more afternoon thunderstorms.

Bottom line: February offers the best balance of lower rainfall and comfortable temperatures for most travelers. Budget-conscious visitors who can handle humidity may find cheaper rates in November.
The trade-off

February’s lower rainfall means fewer indoor breaks — and more direct sun. UV index in Singapore is consistently high year-round, so protection matters every month.

Is Singapore really hot in July?

What is the average temperature in Singapore in July?

  • July has average highs around 31°C (88°F) (Meteorological Service Singapore).
  • It is part of the southwest monsoon season, with frequent afternoon showers.

Does it rain a lot in July in Singapore?

July is not the wettest month, but it still sees about 156 mm of rainfall on average (Weather2Travel (travel climate resource)). Afternoon downpours are common, so plan outdoor activities for the morning.

“July is hot and humid, but the rain usually comes in short, heavy bursts. You can still enjoy the city if you time your outings right.”

— Travel expert, MakeMyTrip

Why this matters

Visitors who assume July is a “dry month” often get caught unprepared. The 31°C heat combined with 80% humidity makes lightweight, quick-dry clothing essential.

What is the most humid month in Singapore?

How does humidity affect the feeling of heat in Singapore?

Which months are least humid in Singapore?

February, August, and March rank slightly lower, but the difference is only a few percentage points. The real takeaway: Singapore is sticky every month.

Bottom line: Humidity is the silent factor that makes Singapore’s 31°C feel like 38°C. December’s 86% humidity is the peak, but any month will test your tolerance for tropical sweat.

What is the rainiest month in Singapore?

What is the average rainfall in November?

Which month has the least rain in Singapore?

February is the driest month, averaging 105.1 mm. The northeast monsoon brings heavy downpours from November to January, while February sits in a brief lull before the inter-monsoon thunderstorms return.

The catch

“Least rain” still means 105 mm — that’s about 10 days of rain per month. No month is truly dry in Singapore.

What is the 60-90 rule in Singapore?

Does the 60-90 rule affect visitors?

The 60-90 rule refers to extreme heat and humidity thresholds used by authorities: when temperatures near 35°C (95°F) and humidity exceeds 70%, public health advisories are triggered. It is not an official tourism metric, but a safety guideline.

What does the 60-90 rule mean for outdoor plans?

If you’re outdoors during a heat advisory, the risk of heat exhaustion rises. Most visitors won’t face the 35°C extreme (Singapore’s highest recorded temperature is 36°C), but the combination of 32°C and 85% humidity can feel just as punishing.

What to watch

The 60-90 rule is a rare trigger — Singapore’s temperatures rarely hit 35°C. But the “feels-like” temperature often exceeds 40°C during humid afternoons, especially in May and June.

Which month should I avoid visiting Singapore?

Is November a bad time to visit Singapore?

  • November and December are often considered less favorable due to monsoon rains and haze risk.
  • Haze from forest fires in Indonesia typically peaks from June to October.

What is the worst time to visit Singapore?

There is no dangerous month, but heavy rain can disrupt outdoor sightseeing. If you want maximum sunshine, February is your best bet. If you’re on a budget, November’s low season offers cheaper flights and hotels.

Bottom line: November’s rain and June’s haze make those months less ideal for outdoor-heavy itineraries. Budget travelers: November is your trade-off — lower prices for wetter days.

What is the coldest month in Singapore?

Does Singapore have a winter?

  • January is the coldest month with average lows of 25°C (77°F).
  • Singapore has no true winter; it is tropical year-round.

What is the lowest temperature ever recorded in Singapore?

The coldest temperature ever recorded was 19.4°C (66.9°F) on 31 January 1934 (Meteorological Service Singapore). That’s still warmer than a spring day in many European cities.

“Singapore’s temperature range is among the narrowest of any country. The difference between the hottest and coolest month is just 1.9°C.”

— Meteorological Service Singapore (NEA), climate data summary

Twelve months, one pattern: the variation is tiny, but the details matter for planning.

January 30.5 25.0 244 84
February 31.2 25.0 105 80
March 31.8 25.3 175 82
April 32.4 25.5 187 83

  • The exact impact of haze in a given year is unpredictable.
  • Month-to-month temperature variations are minimal (under 2°C), making “hottest” a nuance.

Expert perspectives

“Singapore’s climate is so consistent that the difference between the ‘hottest’ and ‘coolest’ month is smaller than the daily temperature swing in many temperate countries.”

— Meteorological Service Singapore (NEA), climate research division

“The 1998 haze episode was a wake-up call. We now have transboundary haze monitoring to protect public health.”

— Ministry of Home Affairs spokesman, Singapore Government

“For a tourist, the real question isn’t temperature — it’s whether you’re prepared for sudden downpours. A lightweight umbrella is your best travel companion.”

— Travel expert, MakeMyTrip

For anyone planning a trip to Singapore, the choice is not between hot and cold — it’s between wetter and drier. The climate data is clear: April is the hottest month by a hair, February is the driest, and every month demands a good umbrella and a bottle of water. For the traveler who wants maximum sunshine, February wins. For the budget traveller, November’s low season brings savings — and rain. The trade-off is yours to make.
