Highest temperature in Los Angeles on July 26?

Platform comparison

Market context

The last 24-48 hours of coverage pointed to a brief Southern California heat surge, with forecasters flagging an extreme heat warning/advisory and temperatures running well above normal before easing later in the week. That matters here because the market resolves off the *day’s* highest reading at LAX, so even if the broader region sees triple-digit heat inland, the airport itself often stays several degrees cooler than the hottest valley locations.[3][5][9][10]

Against that backdrop, the crowd’s split between **80-81°F** and **74-75°F** looks consistent with a coastal airport that is warm, but not usually as hot as inland Los Angeles during heat events. July climatology also leans steady rather than extreme: one forecast source shows daily July highs in Los Angeles generally in the low-to-upper 80s, while another day-level outlook for July 26 puts daytime temperatures around the high 80s, which would leave the market vulnerable to a reading in the upper 70s to low 80s if onshore flow keeps LAX suppressed.[1][2][4][7]

Traders should watch the National Weather Service updates for any last-minute shifts in the heat advisory, marine layer depth, and the timing of onshore winds, because those are the main drivers of whether LAX peaks early and modestly or climbs into the low 80s later in the afternoon.[5][9][10] For settlement, the key input is the highest temperature recorded at Los Angeles International Airport on the calendar day, not the citywide high, so a hot inland afternoon would only matter if it reaches the airport station itself.[1][8]
