December gets roughly 81% more precipitation than July — 287mm against 159mm. That difference, more than temperature, is what changes how a day here feels.
Daytime highs only move 2°C across the whole year (30–32°C), so timing matters far less here than rainfall does.
July is the driest month at 159mm across roughly 11 wet days, while December peaks at 287mm.
May is almost as good as July, but usually quieter and cheaper. If your dates are flexible, it is the easier trip.
Singapore stays fairly consistent all year, so there is no month you need to avoid. What you plan to do matters more than when you go.
Ratings compare months within Singapore, not against destinations worldwide: five stars means the best time to be here, not that Singapore beats anywhere else. Tags describe what the conditions actually suit.

Each month in Singapore is described from long-run climate normals and then rated relative to the other eleven months in the same city. A five-star January in a cold destination means January is one of the best times to be there — not that it beats a Mediterranean summer.
| Factor | Weight | What it measures |
|---|---|---|
| Temperature | Described | Average daytime high and overnight low for the month, shown as measured rather than judged. |
| Precipitation | Described | Monthly millimetres and wet-day count, labelled as snow or rain/snow where temperatures make that the likely phase. |
| Sunshine & daylight | Described | Average daily sunshine hours and astronomical daylight length at mid-month, from the city’s latitude. |
| “Best for” tags | Derived | Applied only when the conditions genuinely support the activity — snow depth-friendly cold for skiing, 13–24°C and low rain risk for hiking, dark evenings at high latitude for aurora. A month with few strong use cases gets fewer tags rather than padded ones. |
| Star rating | Relative | Ranks the month against the other eleven months in the same city. Never a comparison between cities. |
Figures are long-run climate averages, not a forecast for a specific year. Where a month lacks sourced rainfall or humidity, the value is modelled from temperature range and rain frequency.
