Polymarket lists weather markets continuously across temperature, precipitation, snowfall, hurricane and tropical storm categories. Coverage varies by season — summer brings heat-dome markets across Europe and the US South; winter shifts to snowfall thresholds in northern cities; hurricane season opens binary "will it hit X" markets every two weeks.
Liquidity ranges from $2k on niche city markets to $200k+ on flagship US temperature contracts. The bot scans all open markets every 5 minutes, scores each against the local ensemble forecast, and ranks them by edge × liquidity × time-to-resolution.
Currently tracked: 47 active weather markets across 23 cities and 4 continents. The watchlist refreshes automatically as Polymarket lists new contracts — no manual market discovery required.
