Polymarket Weather Resolution Stations: City-by-City Table
Every Polymarket daily temperature market resolves on one specific weather station — almost always an airport ASOS/METAR gauge, not the city center. Trading the wrong station is the most common silent mistake in Polymarket weather markets. This is the reference table: the exact resolution station, ICAO code, and unit for every city with consistent market activity.
Bookmark this page, but read the one caveat first: for cities that run market series on more than one airport (London, Tokyo, Shanghai, Los Angeles, Seoul, Taipei), the station can differ between series. The only authoritative source is the specific market’s published resolution rules — always open the market description and confirm before you trade.
Polymarket Weather Resolution Stations by City
| City | Resolution station | ICAO | Unit | Note |
|---|---|---|---|---|
| New York City | LaGuardia | KLGA | °F, 1°F buckets | Runs cooler than Midtown on summer sea-breeze days. |
| Los Angeles | LAX or Hollywood Burbank | KLAX / KBUR | °F, 1–2°F buckets | Confirm per market. Marine-layer timing is the key edge. |
| London | London City or Heathrow | EGLC / EGLL | °C, 1°C buckets | Confirm per market. Both run cooler than central London. |
| Paris | Le Bourget | LFPB | °C, 1°C buckets | NOT Charles de Gaulle or Orly — the most mistraded station. |
| Tokyo | Haneda or Narita | RJTT / RJAA | °C, 1°C buckets | Confirm per market. JMA MSM is the best local model. |
| Shanghai | Pudong or Hongqiao | ZSPD / ZSSS | °C, 1°C buckets | Confirm per market. Stations sit ~50 km apart. |
| Beijing | Beijing Capital International | ZBAA | °C, 1°C buckets | Single primary station. |
| Hong Kong | Hong Kong International | VHHH | °C, 1°C buckets | Unambiguous station; HKO publishes detailed data. |
| Seoul | Incheon International | RKSI | °C, 1°C buckets | Confirm per market. Coastal — cooler than Seoul center. |
| Taipei | Taiwan Taoyuan International | RCTP | °C, 1°C buckets | Confirm per market. Taipei basin runs warmer. |
| Wuhan | Wuhan Tianhe Airport | ZHHH | °C, 1°C buckets | Single primary station. |
Why the Resolution Station Matters So Much
Retail traders read “Paris” in a weather app and see the city-center reading. Polymarket settles Paris on Le Bourget, a business-aviation airport northeast of the city that runs 1–3°C cooler than the urban core in summer heat events. A trader anchored to the city reading systematically overprices the top temperature buckets — and a bot mapping “Paris” to the wrong coordinates carries that same error on every trade. The station is not a detail; it is the single largest structural edge in several of these markets.
This is exactly the check that separates a profitable system from a leaky one. It is the first thing we look for when evaluating any weather bot on Polymarket: does it resolve against the verified station, or against city-center coordinates?

How to Confirm a Station Yourself
- Open the specific market on Polymarket and read the resolution source in the market rules — do not assume it matches a prior market in the same city.
- Find the station’s ICAO code (the table above is your starting point).
- Pull the forecast at that station’s coordinates — not the city name — from a source like Open-Meteo, and the observed history from Wunderground.
- For how the settled number is actually determined, see how Polymarket weather markets resolve.

Station assignments reflect Polymarket market series active as of mid-2026. Polymarket has changed resolution stations between series before (Paris has used different gauges historically); always verify against the live market rules.
