Highest temperature in Los Angeles on July 22?

Platform comparison

Market context

Los Angeles International Airport’s high for 22 July sits in the **mid-to-upper 70s Fahrenheit** by the market’s own pricing, with **76-77°F** the clear favourite at **93%** and **78-79°F** the main underdog at **7%**.[1] On that framing, the crowd is treating a near-normal airport high as the base case, and the implied **0% YES** in your prompt looks like a stale or mismatched reading rather than a live consensus. The value question is therefore not whether Los Angeles gets warm in an absolute sense, but whether KLAX clears the narrow band the market has already discounted.

For context, this is a classic late-July coastal-Los Angeles setup: airport temperatures are often held down by marine influence, so the distribution tends to cluster tightly around the high-70s rather than the extreme inland heat that dominates headlines. That makes the favourite a relatively safe-looking handicap, while the contrarian angle is any brief onshore-wind weakening, less morning cloud, or hotter-than-expected inland spillover that nudges the airport into the next bracket. AccuWeather’s current Los Angeles reading is already warm at 83°F with very low precipitation and thunder chances, which supports the idea that the broader regional airmass is not cool, even if the airport itself usually lags the city core.[2]

A trader should watch the day’s marine layer depth, the timing of the sea breeze, and whether forecasts for coastal clear-out improve or worsen into the afternoon. The market resolves off the **highest temperature recorded at KLAX** on the calendar day, so the relevant catalyst is not the noon reading but whether there is any late-day lift before the settlement cutoff. No special event or schedule risk is obvious here; the main dependency is the local weather evolution itself, which is why the value tends to sit in the tails only if a sudden warming trend appears in the official and local forecast updates.[1][2]
