Weather radar for the United States, as map tiles

NOAA radar rendered every five minutes with a thirty-minute forecast. Rain totals, lightning and point forecasts behind the same key. Covers the whole country — Alaska, Hawaii, Puerto Rico and Guam included.

No card required. From $29/month after.

An hour of radar, frame by frame

Animated radar loop over the continental United States
Real frames, 2026-10-24 05:40Z to 2026-10-24 06:35Z, five minutes apart. Boundaries from US Census data; the weather is ours.

This is a recording, not a live feed — a public page cannot carry a key worth protecting. Your own integration gets frames this fresh every five minutes, with thirty minutes of forecast past the last one.

Four layers, one key

Radar reflectivity contour bands

Radar

Composite reflectivity from NOAA MRMS, published every five minutes, plus thirty minutes of forecast frames. Smoothed into contour bands rather than the blocky government palette.

Radar intensity scale, 5 to 65 dBZ
light → severe
24-hour rainfall accumulation

Rain totals

How much rain actually fell, corrected against ground gauges, over one hour or twenty-four. The layer that answers whether a river came up, not just whether it rained.

Rainfall scale, 0.01 to 8 inches
0.01 in → 8 in
Lightning flashes over radar

Lightning

Satellite-detected total lightning — in-cloud as well as ground strikes — counted per cell over a rolling fifteen minutes and republished every five. In-cloud activity usually starts first.

Lightning scale, 1 to 100 flashes
1 → 100+ flashes
Surface wind speed

Wind

Surface wind speed and direction from the national analysis, hourly. Same tile scheme, same key.

Two JSON endpoints as well

Point forecast

Current conditions, hourly for twelve hours, and seven days, for any coordinate. Temperature, wind, humidity, pressure, precipitation probability.

GET /forecast/39.95,-105.36

Historical conditions

What the weather actually was at a point and a moment — temperature, wind, pressure, precipitation. Back to 2013.

GET /history/39.95,-105.36/2026-10-18T15:00Z

Most radar providers stop at tiles. These are the reason customers stop needing a second vendor.

Coverage, stated plainly

Included

  • Continental United States
  • Alaska
  • Hawaii
  • Puerto Rico and the Caribbean
  • Guam

Not included

  • Lightning in Alaska or Guam — the satellite's field of view ends near 54°N, and Guam is outside it
  • Rain totals in Hawaii — the national analysis does not publish them there
  • Anywhere outside the United States

Better you read this now than find it in production.
