Not downtown Los Angeles

Kalshi's Los Angeles market settles on LAX (KLAX) and nothing else. Downtown Los Angeles (KFHM) publishes its own climate report, with its own daily high, which doesn't count.

Downtown Los Angeles (KFHM) against LAX, 20 km apart

Over 360 days (Oct 21, 2025 to Oct 20, 2026), the two official highs were the same whole degree on 12 of 360 days (3%). Downtown Los Angeles was warmer on 330 and cooler on 18, +6.0°F on average, and 2°F or more apart (a bracket's width) on 317.

Widest gaps: Nov 10, 2025, KFHM 92° and KLAX 70°; Dec 17, 2025, KFHM 68° and KLAX 74°.

Los Angeles on Polymarket

Polymarket's Los Angeles market settles on the same station, Los Angeles International Airport (KLAX), but reads it its own way: the highest of the day's hourly readings in whole °F, over the local calendar day, in 2°F ranges.

Did the afternoon report's high hold?

On 176 days from May 1, 2026 to Oct 29, 2026, the NWS's afternoon preliminary report (usually "as of 5 PM" local time) had the same high as the final report on 174 of 176 days (99%). The final report came in higher on 2 and never lower.

1 of those 2 higher finals put the high after the 5 PM cutoff.

On 1 daythe NWS sent a second final report with a different high. Kalshi's contract terms use the first one: Oct 22: 72°, then 71°.
