Weather in Singapore in March

March is a good time to visit Singapore if you want reliable heat and can work around frequent rain, rather than depend on clear skies. Daytime temperatures average 29°C, nights stay around 25°C, and about 24 days have measurable rain. For a UK traveller, the main adjustment is the combination of warmth and humidity: pack light clothes, keep plans flexible and do not expect evenings to bring much cooling relief.

Daytime and night-time in March

The typical March day in Singapore peaks at 28.9°C, but that is an average: the warmest 10% of days reach 30.1°C or more. About 100% of days top 25°C and 1 in 8 pass 30°C. Nights average 25.3°C; one night in ten drops to 24.5°C or lower, so pack a layer for evenings. Between 1991 and 2020 the hottest March day here reached 33.7°C (2019-03-02) and the coldest night 23.2°C (1999-03-02).

Rain in March

Wet (more than 8 rainy days): about 24 days with 1 mm or more, 208 mm in total. Year to year it varies a lot - the wettest March was 1994 with 395 mm, the driest 2014 with 105 mm. Humidity averages 83%, which makes the heat feel heavier than the thermometer suggests.

Sunshine and daylight

Around 2.8 hours of sunshine a day (estimated from cloud cover), 12.0 hours of daylight: the sun rises about 07:10 and sets about 19:17 local time in mid-March. Average cloud cover is 77%.

Is March a good time to visit Singapore?

It is a reasonable choice: hot days but expect showers. The best months for Singapore on our scoring are July, June, March; months averaging 25°C or more: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec.

Hot days, warm nights and little relief from humidity

March ranks as Singapore's warmest month, but the challenge is persistent warmth rather than extreme daytime temperatures. With humidity at 83%, allow for a sticky feel and take breaks from walking, particularly around midday. Loose, breathable clothing is more useful than heavy layers, and a change of top may be welcome after time outdoors. The average night low of 25.3°C means dinner outside still calls for light clothing, not the warmer outfit you might pack for a European spring evening. This suits travellers who enjoy heat; if you need crisp mornings or cool nights to feel comfortable, March is a poor fit.

Plan for wet weather, not a sunshine-led holiday

Rain is a routine part of the March weather, so make outdoor plans easy to rearrange and keep an indoor alternative in mind. A compact umbrella and footwear that can cope with getting wet are sensible additions to your bag. There are about 2.8 hours of sunshine within 12 hours of daylight, so long days do not translate into long spells of direct sun. Frequent rainy days do not necessarily mean continuous rain, but it would be unwise to rely on a dry outing. March works better for a flexible city holiday than for a trip built around dependable sunshine.
