Planning a trip to the Lion City? One of the most common questions travelers have is about the weather. Located right near the equator, Singapore is known for being hot and humid year-round, but there are subtle differences you should know to plan the perfect trip.
Here is everything you need to know about Singapore’s seasons, monthly weather breakdowns, and what to pack!
General Climate: What to Expect
Singapore has a typical tropical rainforest climate. This means it is hot, humid, and rainy throughout the year.
- Temperature: Consistent year-round, averaging 26°C to 28°C (79°F – 82°F).
- Humidity: Very high, averaging over 80%.
- Seasons: There are no distinct four seasons like in Korea. However, the year is generally divided into the Wet Season (Nov–Jan) and the Dry Season (Jun–Aug).
- Even outside the rainy season, you can expect sudden, short showers known as squalls (localized thunderstorms).
Singapore’s Seasons
The Dry Season (April – September)
Best for: Outdoor activities and sightseeing.
Details: The driest months are typically June to August. While it is called the “dry season,” it doesn’t mean zero rain—afternoon showers are still common but usually brief.
Warning: This is also the hottest time of the year, with temperatures hitting 31°C–33°C. UV rays are very strong, so sun protection is a must.
The Wet Season (November – March)
Best for: Indoor activities, museum hopping, and enjoying the festive atmosphere.
Details: Influenced by the Northeast Monsoon, December and January see the heaviest rainfall. Expect overcast skies and long periods of rain.
Note: The rain brings slightly cooler temperatures (avg. 24°C–25°C), but the high humidity makes it feel muggy. January can also be quite windy.
Haze Season (Sumatra Forest Fires)
Between June and September, Singapore sometimes experiences “Haze” caused by smoke from forest fires in nearby Sumatra, Indonesia, carried over by southwest monsoons.
The smoke contains fine particulate matter that can irritate the eyes and throat.
Tip: If you are traveling during these months, check the PSI (Pollutant Standards Index). Sensitive groups should carry a KF94 mask just in case.
Best Time to Visit Singapore
The “best” time depends entirely on your travel style:
| Goal | Best Months | Why? |
| Nice Weather | Feb – Apr | Least rain, plenty of sunshine, and great for outdoor fun (Sentosa, Zoo). |
| Shopping | Jun – Jul | The Great Singapore Sale (GSS) takes place. Expect huge discounts! |
| Budget / Quiet | Aug – Nov | considered “Off-Peak” (except during the F1 Grand Prix in mid-Sep). Lower hotel rates and fewer crowds. |
| Festivals | Dec – Jan | Christmas light-ups and Chinese New Year vibes, though it is the rainy peak season. |

FAQ: Frequently Asked Questions
Q: Is the air conditioning really that cold?
A: YES. Malls, cinemas, and the MRT (subway) blast the AC. While it is 30°C outside, it can feel like 20°C inside. Always carry a light jacket or long-sleeved shirt to prevent catching a cold from the temperature shock.
Q: Do I need to worry about the Haze?
A: Usually, yes, between June and September. While strict regulations have reduced it in recent years, it’s unpredictable. Check the air quality forecast before you fly.
Q: When is the absolute cheapest time to go?
A: August to October. (Avoiding the F1 Grand Prix week in mid-September). This is the lull between the summer shopping craze and the year-end holidays.
