Markets on the highest or lowest temperature at one named weather station on one calendar day. You buy the bucket you think the day lands in.
The station named in that market's own rules, identified by its ICAO code. Each city page on this site lists the station we track for it.
It is informal shorthand for the afternoon peak having passed, so the day's maximum is very unlikely to change before settlement.
From our own calibrated sensor mesh. The method is proprietary. It is always shown next to the official station reading, never instead of it.
The free feed is delay shifted by 7.77 minutes. Pro and Elite see the realtime feed.
Pro (25 USDC a month) adds the realtime feed, the committed daily forecast and the full bucket ladder. Elite (399 USDC once) adds the multi day outlook, the intraday distribution and the full signal set.
You connect a wallet and trade on Polymarket through the terminal. Orders execute on Polymarket and settle on the official station reading.
No. PollyWetter never takes custody. Your wallet holds your funds and orders execute on Polymarket.
No. There is no email signup and no password. Access is tied to the wallet you connect.
Polymarket is not available everywhere. You are responsible for the rules where you live, and you must be 18 or older, or the legal age where you live.
No. PollyWetter is an information tool. Nothing on the site is financial advice.
We publish a daily scorecard grading every settled market against the official reading, and a rolling error figure per station. Judge it from that record rather than from a claim.
Pro is month to month and simply stops when the paid period ends. There is nothing to cancel and no auto renewal. The Elite pass is a one time purchase.
