About Weather Arena
Weather forecasts differ from site to site. That’s why we compare and verify them.
Weather Arena lines up forecasts from every provider and fairly audits their hits and misses so you can trust the numbers, not slogans.
Our mission
Reconcile each provider’s forecast against actual outcomes.
Highlight which forecasts are reliable — and which fall short.
Raise transparency so anyone can choose the right forecast with confidence.
How we make it happen
Collect: Pull data from multiple forecast APIs on a regular cadence.
Normalize: Map each provider’s wording to Weather Arena’s unified three-digit codes.
Compare: Line forecasts up by location and date for side-by-side review.
Verify: Match forecasts with observed data and quantify the gaps.
Refresh: Recalculate scores and rankings whenever new data arrives.
