Weather Maps API

https://api.rainviewer.com/public/weather-maps.json

Purpose and Description

Contains the past (2 hours) and forecast (30 minutes) weather radar data and the past infrared satellite data (2 hours). Suitable to display in the applications, on the websites, or in any other mapping software. It can also be used as a source for the weather API.

Database File Example

Here is an example of the weather maps API file with two frames for each data section. The data inside the example is out of date and cannot be used in real queries. To get actual data, please open the API file directly.

If you enjoy our API and want to keep it free for as long as possible, please support us at Patreon. You will also get access to the weather radar database API, 60 minutes of weather radar nowcast map, and a possibility to get tiles in your own custom color scheme.

How to use host and path information

Like the legacy API, you should use the host and path data from the API as a part of the URL. All available URLs and their parameters are described below.

Each url starts with {host}, where:

URLDescription
{path}/{size}/{z}/{x}/{y}/{color}/{options}.pngRadar data: displays one tile with the composite radar reflectivity data, with specified size, color scheme, and additional options.
{path}/{size}/{z}/{lat}/{lon}/{color}/{options}.pngRadar data: same as the link above, but with the center at specified coordinates (EPSG:4326) with desired zoom size. Great for widgets
{path}/{big_size}/{color}/{options}.pngComposite image with radar reflectivity for the entire world. Generates slowly, up to 10 seconds per image loads. Cannot be smoothed. IMPORTANT: color scheme and the snow mask for satellite data should always be “0”.
  • {ts} – one of the available Unix timestamps from the API.
  • {x}, {y}, {z} – x, y, and zoom level of the tile that you want to download. Read more about tiles
  • {latitude}, {longitude} - latitude and longitude of specific coordinates accordingly. Decimal format. Must contain a dot in the number. Example: -32.7892, 108.67821.
  • {size} – image size, can be 256 or 512.
  • {big_size} – can be 2000, 4000, 8000, 16000, or 24000 (24000x12000 px or ~2km per pixel). For square images use 4096, 8196, and 16384 accordingly.
  • {color} - the number of the color scheme from the provided list.
  • {options} – list of options separated by the _ symbol. For example: ‘1_0’ means smoothed (1) image without snow color scheme (0). Now two options are available: {smooth}_{snow}
    • {smooth} - blur (1) or not (0) radar data. Large composite images are always not smoothed due to performance issues.
    • {snow} - display (1) or not (0) snow in separate colors on the tiles.

Weather Radar Coverage

Additionally, one more product is available: the weather radar coverage mask. This mask shows where is weather radar coverage available (transparent areas) and where is not (black areas). We don’t update this mask often. The links are the same as for radar and satellite products, but without options and color scheme.

URLDescription
/v2/coverage/0/{size}/{z}/{x}/{y}/0/0_0.pngCoverage tile: where radar data is available (transparent areas) and where is not (black areas).
/v2/coverage/0/{size}/{z}/{lat}/{lon}/0/0_0.pngCoverage data as above but for specified center coordinates (latitude, longitude).
/v2/coverage/0/{big_size}/0/0_0.pngComposite coverage tile for the entire world at once. Generates slowly.
