Weather Markets turns tomorrow’s forecast into a daily game. Instead of just checking whether it will rain, you make a call: YES or NO on whether Amsterdam’s high tops a set temperature, whether London sees measurable rain, whether New York gets strong wind gusts, or whether Tokyo gets a thunderstorm. Crowd estimates move like a prediction market, but every point is play money and leaderboard-only, with no cash value.
Thresholds are pulled from the forecast so each market opens near a genuine 50/50, which makes them a fair test of judgement. Markets close at midnight local time, before the weather happens, then settle the next morning against the Open-Meteo historical archive. Read the full rules or see who is forecasting best on the leaderboard.
The game is also built around climate resilience: monthly community play can help direct a site-funded donation to practical climate causes, and the rules avoid disaster-suffering questions such as deaths, homes destroyed, wildfire damage, or active emergencies.
Weather Markets is a free weather forecasting game where you try to beat tomorrow’s forecast in 17 world cities — Amsterdam, London, Paris, Berlin, Madrid, New York, Chicago, Miami, Los Angeles, San Francisco, Seattle, Tokyo, Seoul, Hong Kong, Singapore, Sydney, and Auckland. You make YES or NO calls on whether the temperature, rain, wind, or a thunderstorm will beat a threshold, and every result settles automatically on public weather data.
No. Every player starts with 10,000 play points that have no cash value. Monthly play helps direct a site-funded climate resilience donation, but points cannot be cashed out or redeemed. It is a forecasting game, not a betting service or financial product.
Each market asks a yes-or-no question about tomorrow’s weather. You forecast YES or NO against a live crowd estimate. A call shown at 30 points means the crowd currently sees a 30% chance, and your forecast nudges the estimate.
Markets close at midnight local time, before the day they describe, then settle the next morning against the Open-Meteo historical weather archive and nothing else. If the archive has not published yet, the market stays pending and retries.
Correct forecast units earn 100 points after settlement, while incorrect units earn nothing. Forecast better than the crowd, judge uncertainty well, and your play-point balance grows. Rank on the leaderboard by return on your starting points.
Weather Markets is designed as a free forecasting and climate-literacy game. The site can fund a monthly climate resilience donation, and community forecasting helps decide which vetted cause receives attention or allocation. The donation is never paid to players and does not depend on bad weather happening.
No. Weather Markets avoids questions about deaths, injuries, homes destroyed, wildfire damage, disaster losses, or named active disasters. Serious official warnings can also pause affected-city challenges so the page can point people toward preparedness information instead of play.
17 cities spread across time zones — from the US west coast to Europe, Asia, and Oceania — so a market is almost always about to close: Amsterdam, London, Paris, Berlin, Madrid, New York, Chicago, Miami, Los Angeles, San Francisco, Seattle, Tokyo, Seoul, Hong Kong, Singapore, Sydney, and Auckland. Each city runs separate markets for temperature, rain, wind gusts, and thunderstorms.
Yes. Weather Markets is completely free. Claim a username on your first call, start with 10,000 points, and play as much as you like.
