A climatology terminal for temperature markets
Live METAR and decoded TAF, seven forecast models scored against what each station actually recorded, and five years of hourly climatology — for every station a market settles on.
What you get for a station
The climb to peak
At 06:00 a station has most of its warming ahead of it; by 16:00 it usually does not. We hold the hourly distribution for every day of the year, so the page can say how much further this station typically climbs from the hour it is in now — and how often the peak is already behind it.
Which model to trust here
Seven forecast models scored against what the station actually recorded, per city. The best model is not the same everywhere: in a typical city the best and worst are 1.7°C apart, and 37 of 51 markets show a gap over a degree.
Wind regime
Which wind directions run warm or cold at this station, measured against its own day-of-year normal, by season. A southwesterly means something different in London than it does in Seoul.
The aerodrome forecast
The station's own TAF, decoded into plain language, including the forecast maximum where the issuing service publishes one.
Pro, from 1 February 2027
Everything is open right now. From 1 February 2027, Pro watches the stations you choose and tells you what they are doing — so you are not checking forty-six of them yourself every morning:
- a watchlist — pick the stations you actually trade, once
- a morning brief on just those: how far from normal, how much climb is left, whether the peak has passed
- an alert when one of them breaks from its own climatology
- a settlement recap — what the station recorded, beside what the book had priced
- break history — every time a station broke 3° from normal in five years, and where the day finished
- the full station board, beyond the first five
No wallet, ever. Nothing to connect and nothing to type in daily — you pick your stations once. Every station page, the model scoring, the climatology depth and the top of the board stay free, for everyone, with no account.
One message before anything changes. Nothing else, ever, and your address is not shared or sold. Questions: hello@tempterminal.com
Where the numbers come from
Every figure traces to a public source, and the page says which. Station observations and climatology are Iowa Environmental Mesonet ASOS archives, which are public domain. Forecasts are Open-Meteo. Aerodrome forecasts are NOAA. 53 temperature markets at 48 airport stations. 5 settle on the day's low, the rest on its high, and each low market shares a station with its high twin. 51 of them have enough scored history to rank forecast models. Rebuilt every thirty minutes.
