Highest temperature in Los Angeles on August 9?

Platform comparison

Market context

Los Angeles International Airport’s temperature on 9 August 2026 is the event here, and the crowd is treating the **80–81°F** bin as the favourite while the current market implies **0%** for YES. That looks like an extreme pricing signal rather than a meaningful forecast, because the question is not whether Los Angeles will be warm, but whether the day’s peak lands in the specific resolution band used by the market.

Historically, early-August highs at LAX usually sit in the upper 70s to low 80s, with occasional pushes into the mid-80s when inland heat spills west; WeatherSpark and Weather Underground’s historical pages both show Los Angeles-area August temperatures clustering around that range, while Weather Underground’s KLAX observations are the relevant source for settlement. That makes the consensus outcome the mid-range bins, not the tail ends, and it also means the main value spot is usually in understanding whether marine layer influence keeps the airport cooler than inland neighbourhoods. Extreme-heat outcomes can happen, but at the coast they depend on a broader regional warm-up rather than a single hot afternoon. [4][17][18]

For traders, the key catalysts are the daily marine layer, any late-summer heat advisories for Southern California, and whether offshore flow develops enough to suppress morning cloud cover and lift the daytime maximum. The National Weather Service forecast pages and climate reports are the practical watchpoints for those dependencies, while local news often flags when heat is building into the basin; ABC7 and the LA Times have both recently highlighted Southern California heat episodes and weaker Santa Ana influence as the kind of setup that can move airport temperatures higher. In handicapper terms, the favourite remains the moderate-high bin, the underdog is a cooler-than-normal coastal day, and the contrarian angle is any late surge in offshore warming that nudges LAX above the consensus band.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Who Will Win 2026, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
