Raindrop's Rainfall & Precipitation Data API
Precipitation data that isn't just guesswork
Most weather APIs post previous forecasts as historical data. We store real-time sensor data for the past 11 years, to give rainfall totals accurate to within 0.05 inches.
Why Raindrop?
Most weather APIs recycle old forecast predictions and call it "historical data." We store actual measurements from real sensors.
Recycled forecast model outputs — essentially past predictions, not measurements.
Actual observed data from 10,000+ NOAA sensors — Doppler radars, satellites, and rain gauges.
Grid-averaged data that misses local variability. Accuracy degrades at point level.
Accurate to 0.05 inches at 1 km resolution — the same data the National Weather Service relies on.
Often 1–2 years of history, or requires expensive enterprise tiers for full access.
11+ years of historical data (Jan 2015 – present) included on all plans. No hidden paywalls.
