Highest temperature in Los Angeles on July 9?

Platform comparison

Market context

The underlying event is the daily high temperature recorded at Los Angeles International Airport on 9 July 2026, a date historically prone to marine layer cooling that suppresses peak heat. Current crowd-implied probability sits at 0% for the highest range, reflecting a market consensus that extreme heat is unlikely at the coastal station. Historical data shows July highs at KLAX typically range from 79°F to 90°F, with the average hovering near 85°F, yet the immediate coastal influence often keeps temperatures 4°F below the inland July normal of 74°F for the modal bracket [1][9]. Recent heatwaves in Southern California have shattered records inland, reaching 90–105°F in interior zones, but the inland coastal plain including downtown and the airport usually remains cooler at 80–90°F, suggesting the 0% probability aligns with the persistent marine buffer [2][4].

Traders must watch the strength of the marine layer and any sudden shifts in wind patterns that could breach the coastal cooling shield. A key catalyst is the National Weather Service point forecast for KLAX, which currently predicts a high near 70°F under a strong marine layer, significantly below the seasonal norm [9]. Additionally, monitor the heat advisory schedules for Los Angeles County, as recent advisories have targeted interior zones while sparing the airport region, indicating a dependency on inland pressure systems that rarely penetrate the coast [2]. The resolution hinges on Wunderground’s recorded maximum for all times on 9 July, so any unforecasted wind surge or cloud cover reduction could alter the outcome, though current form suggests the marine layer will hold firm [6].

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
