PollyWetter is a live trading terminal for Polymarket weather markets. It puts the official station reading, a calibrated live estimate, the market's own prices and one click trading on a single screen.
Daily high and low markets for 51 stations, with the official reading and the running extreme for the settlement day.
Monthly accumulation against the long run normal for the same point in the month.
Daily PM2.5 with the reading and the reported band. No health verdicts.
A calibrated estimate from our own sensor mesh, always displayed beside the official figure.
Most tools show either weather or market prices. PollyWetter shows the official station data and the live order book side by side, with our own accuracy record published next to our estimate so it can be checked rather than believed.
People trading Polymarket weather markets, and people who want to see how a weather prediction market actually prices a day.
Readings come from official station sources and public air quality feeds. Prices and order books come from Polymarket. The calibration method is proprietary. Our forecast accuracy is published daily.
