Polymarket New York temperature: settles on KLGA

KLGA is LaGuardia Airport, New York. Polymarket settles temperature contracts here. Below: the resolution source each venue names, when the station reports, and how long a reading takes to reach the public feed.

This city settles on two different stations

Polymarket uses KLGA (LaGuardia Airport). Kalshi settles the same city on KNYC (Central Park) instead. The two sites can report different temperatures at the same moment and land in different contract buckets on the same day, so a reading from one tells you nothing definitive about the other.
