What's Singapore Rain Map?

This application shows rainy areas inside Singapore and notifies you of coming rain to your location. And transition of PSI measurement, which is a trend topic on air pollution (Haze), also is indicated as graph on it.

The scope of function to display raining area is expanded peripherally to a part of Malaysia and Sumatra (Indonesia) from only Singapore. Resolution of RainMap is automatically tuned up to the map resolution you are looking at. If you magnify a map within Singapore, you can get information on raining conditions at the shorter interval and at the smaller district. To make renewal interval longer, please change your map scale where you can find both of Malaysia and Sumatra on your map and you can grab weather conditions in the larger area. We recommend you would utilize well each scale for your purpose.

Additional Information

  • Notifications

    Rain and Haze information is displayed based on data the National Environment Agency of Singapore and Meteorological Service Singapore provides.

    As it is updated by 5-10 minutes, you can see rain transition for the past 60 minutes by animation, and the amount of rain fall indicated by color; blue, green, yellow, red from small to large. IIn rare cases, when the service providing data would be under maintenance, correct date cannot be obtained.

    We appreciate that you understand this situation. Range of information on rain fall this application offers is mainly limited to domestic area in Singapore.

    1) Flash flood could occur if prolonged heavy rain coincide with high tide.
    2) Heavy showers generally imply high chance of lightning occurrence.
    3) Patches of green areas that are small and static may not be due to presence of rain.

    The rate caught in a shower for rankings is calculated by own criteria our company sets in its way.
