Weather in Singapore in December
December falls within Singapore's monsoon season, so expect plenty of rain showers, though they often come in short, intense bursts rather than all-day downpours. Temperatures remain consistently high, with averages ranging from a low of 75°F (24°C) to a high of 88°F (31°C). Humidity is perpetually high, often hovering around 80-90%, making everything feel even warmer. You can expect around 12 hours of daylight, so there's plenty of time to explore between showers.
What to wear in Singapore in December
Embrace lightweight, breathable fabrics like cotton, linen, and moisture-wicking materials for all your clothing. Singaporeans generally dress smartly casually, so while shorts and t-shirts are fine for daytime exploring, you might want to pack a few nicer outfits for evening dinners or visits to religious sites. Always carry a light jacket or cardigan for air-conditioned indoor spaces, which can be surprisingly chilly.

Pro tips
Stay Hydrated Constantly
The high heat and humidity can lead to dehydration quickly. Drink plenty of water throughout the day, and don't hesitate to pop into a hawker center for a refreshing fresh fruit juice.
Utilize Covered Walkways
Many parts of Singapore, especially in the downtown core, have extensive covered walkways and underground tunnels. These are a lifesaver for escaping both the rain and the sun.
Book Festive Events in Advance
December is a popular time for holiday events and light-ups, especially at Gardens by the Bay. If you have specific activities in mind, book tickets or make reservations well in advance to avoid disappointment.
Pack for Both Rain and Shine
Don't let the monsoon season deter you! Many attractions are indoors, and the rain often passes quickly. Be prepared for both scenarios, and you'll have a fantastic trip.
