How airport daily-high temperature markets settle
A daily-high temperature market resolves to the maximum temperature reported for one specific weather station on a given local day. Which station, which data source, and how it is rounded differ from city to city — and that difference is often the line between a winning and a losing position. Below is how each city we track resolves, to the best of our knowledge.
⚠️ View-only information, not betting or financial advice. Settlement sources and rules can change — always confirm against the specific market's official resolution criteria before acting.

Easy mistakes to avoid
- Chengdu: Unlike the others, the high is taken from the hourly (on-the-hour) observations. A spike between the hours may not count.
- Shenzhen: ⚠️ Weather Underground is currently serving incorrect ZGSZ data that does not match the official airport ASOS. Verify against the official observation before trusting any ZGSZ figure for resolution.
- Taipei: A common mistake: these markets resolve on downtown Songshan (RCSS), not the larger Taoyuan international airport. The two can differ by a degree or more.
- Hong Kong: Unique on this list: settles on the HKO headquarters station to 0.1 °C, not the airport METAR. Use the HQ reading and the finer precision.
- Paris: The Paris market resolves on Le Bourget (LFPB), the smaller close-in airport — not the larger Charles de Gaulle (LFPG). The two can differ.
- New York: The New York market resolves on LaGuardia (KLGA), not JFK (KJFK) or Newark (KEWR). US markets bracket in °F.
- Dallas: The Dallas market resolves on Love Field (KDAL), not the larger DFW (KDFW). US markets bracket in °F.
- Houston: The Houston market resolves on Hobby (KHOU), not Bush Intercontinental (KIAH). US markets bracket in °F.
