Singapore weather by month
June, July and March are good months to choose for Singapore, while February is the better option if avoiding rain is your priority. Daytime averages stay between 28°C and 29°C throughout the year, so there is no genuinely cool season to aim for. February has the fewest rainy days at 17, but still needs a flexible plan. The main seasonal trade-off is sunshine and rain, rather than warmth: expect warm evenings and pack for showers whenever you travel.

January to May: February offers the clearest rain advantage
January is the coolest month, but average days of 28°C and nights of 25°C hardly call for a winter wardrobe. February brings the strongest reduction in rain, with 17 rainy days and 3 hours of daily sunshine, making it a sensible choice for travellers who want more time outside. March stays appealing for sunshine, though its 24 rainy days mean you should keep plans flexible. April and May are less forgiving if rain disrupts your holiday: both average 28 rainy days and just 2 hours of sunshine. Their 26°C nights also offer little cooling after a warm day, so light clothing remains useful well into the evening.
June to September: steady warmth and more sunshine
June and July offer a useful balance of warmth and sunshine, rather than a dry-season guarantee. June averages 29°C by day, while July eases to 28°C; both have 3 hours of daily sunshine. August and September keep much the same pattern, with 28°C days and 26°C nights. Across these months, rain occurs on 24 to 25 days, so outdoor plans still need room to change. This period suits travellers who can work around wet weather without expecting long stretches of clear sky. Keep the middle of the day unhurried, wear light clothing and carry rain protection rather than treating sunshine as a promise.
October to December: warm, but less suited to sunshine-led trips
October marks a less favourable stretch for travellers prioritising sunshine, with 27 rainy days and 2 hours of sun daily. November and December each average 28 rainy days and only 1 hour of sunshine, making them harder months to recommend for a holiday built around being outdoors. November is the wettest month, so it particularly suits travellers comfortable changing plans for rain. Temperatures remain steady across this period at 28°C by day and 25°C at night; the catch is wet weather, not cold. Pack light clothes alongside rain protection, and leave outdoor time flexible rather than relying on a fixed schedule.

Is the sea warm enough for swimming throughout the year?
Sea temperatures stay between 28°C and 30°C, so water temperature is unlikely to be the obstacle in any month. April, May and June have the warmest sea averages. Choose your timing around rain and sunshine rather than expecting a cold-water season.
Will I need warm clothes for evenings?
