SunticUV index in Singapore today
Singapore sits almost on the equator, so the sun is high overhead and UV runs very high all year, every month. The only accurate figure is a live one for your exact spot: Suntic shows Singapore's real-time UV index and a 10-day forecast.
Sun and UV in Singapore
Just north of the equator, Singapore has the sun nearly overhead year-round, and midday UV regularly reaches very high or extreme levels in every season. The tropical climate brings frequent cloud and sharp downpours, but these are often brief and broken, doing little to reduce the overall UV. High humidity makes the heat feel intense while UV stays strong even on hazy days.
When is UV highest in Singapore?
UV is highest around solar noon (broadly 10am to 4pm) and strongest across almost the entire year. The exact peak shifts with the season and the day's weather. For more on this, see when is the sun strongest.
The UV index scale
| UV index | Risk level | What to do |
|---|---|---|
| 0-2 | Low | Minimal risk. Safe to be outside; sunglasses on bright days. |
| 3-5 | Moderate | Take care at midday. Use SPF 30+, a hat and shade around noon. |
| 6-7 | High | Protection needed. SPF 30+, cover up, seek shade 10am-4pm. |
| 8-10 | Very high | Extra protection. Avoid the sun at midday; SPF, clothing and shade are essential. |
| 11+ | Extreme | Take all precautions. Unprotected skin can burn quickly; stay inside or fully covered at peak hours. |
UV index categories follow the World Health Organization / US EPA scale.
Staying sun-safe in Singapore
- There is no low-UV season here, so protect your skin year-round, not just on holiday.
- Hazy or cloudy tropical skies still let strong UV through, so don't skip protection on grey days.
- Long days walking the city or by the pool mean steady cumulative exposure; reapply regularly.
Wherever you are, the basics hold: use broad-spectrum SPF 30+, seek shade around midday, cover up, and never let your skin burn. See our sunburn prevention tips.
