Live Rain Radar for Singapore
The rain radar shows where it is actually raining across Singapore right now, plotted straight onto the map. You can watch rain areas drift over the island and across the Johor Strait, so you can tell whether a shower is moving towards you or already clearing out.
The picture refreshes every few minutes. It comes from NEA's rain-areas radar, published through data.gov.sg, so what you see is close to live and not a forecast from earlier in the day. Heavier rain shows up in warmer colours, light drizzle in cool blue.
Most drivers use it the simple way. Check it before you leave to see if you need to wait out a storm, or glance at it mid-trip to work out if the downpour ahead is going to pass. Want to know if it is raining this very second? Open the live radar below. This page describes how it works, but the moving picture lives on the map.
Rain intensity legend
What the radar colours mean and how each one feels on the road.
| Colour | Intensity | What to expect on the road |
|---|---|---|
| Light | Drizzle to light rain. Wipers on low, roads a bit wet but traffic still moves fine. | |
| Moderate | Steady rain. Slower traffic, longer braking distance, keep your lights on. | |
| Heavy | Heavy downpour. Ponding likely on the expressways, visibility drops, give the car in front more room. | |
| Intense | Thunderstorm cell. Flash-flood risk in the usual spots, consider waiting it out for 15 to 20 minutes. |
How to read the radar
Cooler blue means light rain and warmer red means the heaviest cells, usually thunderstorms. Watch which way the blobs are sliding. In Singapore they often push in from the west or off the Strait, so if a red patch is upwind of you, it is likely heading your way. If it is downwind and shrinking, the rain near you should ease off soon.
Frequently asked questions
Is it raining in Singapore now?
This page cannot show you the live pixels, but the map can. Tap "Open live rain radar" and you will see exactly where the rain is falling right now, colour-coded by how heavy it is. If the island looks clear, you are good to go.
How often does the rain radar update?
The radar refreshes every few minutes, in line with how often NEA publishes new rain-area frames on data.gov.sg. So the picture you see is close to real time, not a forecast from this morning.
Where does the rain data come from?
The rain areas come from NEA's weather radar, served through data.gov.sg. We just plot it on the map over Singapore and the Johor Strait so you can read it at a glance.
Will it rain today in Singapore?
The radar shows what is happening now and where the rain is drifting, which is the honest way to tell if a shower is heading your way in the next half hour. For the full-day outlook, check the NEA 2-hour and 24-hour forecast. Afternoon thunderstorms are common all year, so a clear morning does not mean a dry evening.
Does the rain radar work on my phone?
Yes. Open the map in your phone browser and the radar sits right on top of Singapore. You can pinch to zoom into your area, and if you install RoadKaki as an app it loads even faster the next time you check.
