Your April weather guide
HotWeather in Singapore in April
April suits a Singapore trip if you want reliable heat and can accept frequent rain, but it is a poor choice for a holiday built around sunshine. Daytime temperatures average 29°C, nights stay around 26°C, and about 28 days see rain. For a UK traveller, the bigger adjustment is the combination of warmth and humidity, with little cooling after dark. Go with flexible plans rather than expecting long, clear spells outdoors.

How April compares

Daytime and night-time in April
The typical April day in Singapore peaks at 28.9°C, but that is an average: the warmest 10% of days reach 29.9°C or more. About 100% of days top 25°C and 1 in 12 pass 30°C. Nights average 25.7°C; one night in ten drops to 24.9°C or lower, so pack a layer for evenings. Between 1991 and 2020 the hottest April day here reached 31.0°C (2019-04-05) and the coldest night 23.8°C (2008-04-01).
Rain in April
Wet (more than 8 rainy days): about 28 days with 1 mm or more, 242 mm in total. Year to year it varies a lot - the wettest April was 2008 with 327 mm, the driest 1999 with 161 mm. Humidity averages 84%, which makes the heat feel heavier than the thermometer suggests.
Sea temperature in April
The sea averages 29.6°C - warm enough to swim (22°c+). Depending on the year it ranges from 29.2°C to 30.2°C. For the warmest sea here, come in May (30.1°C).
Sunshine and daylight
Around 2.4 hours of sunshine a day (estimated from cloud cover), 12.0 hours of daylight: the sun rises about 07:00 and sets about 19:09 local time in mid-April. Average cloud cover is 80%.
Is April 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.
Expect sticky heat, including in the evening
April is among Singapore's warmest months, and the heat is persistent rather than confined to occasional hot days. Humidity averages 84%, so even an unhurried day outdoors can feel sticky. London's April daytime average is 13.5°C, making this a substantial change from spring at home. Pack loose, breathable clothing and allow for indoor breaks rather than planning to stay outside through midday. Evening plans will not need the sort of warm layers you might use in the UK, though a light layer can be useful indoors. This month suits travellers comfortable with sustained warmth; it is less appealing if you rely on cool nights to recover.
Keep outdoor plans flexible
Rain is the main catch: April is wet enough that you should plan for it throughout your stay, not treat it as an unlikely interruption. Carry an umbrella and a waterproof pouch for anything that needs to stay dry, and choose footwear you can tolerate getting wet. There are about 2.4 hours of sunshine within 12 hours of daylight, so long days do not translate into long sunny spells. Keep outdoor time movable and have an indoor alternative ready. The figures do not tell you when rain will arrive or how long each spell will last, so do not build your plans around an assumed dry morning or a brief afternoon shower.

Would another month be a better choice?
July, June and March rate better overall than April. April still suits travellers who prioritise warmth and can work around rain, but it is not the strongest choice if you have flexible dates and want a better overall weather balance.
How long is the flight from London?
