Highest temperature in Mexico City on July 24?

Platform comparison

Market context

Mexico City's highest temperature on 24 July 2026 will be measured at Benito Juárez International Airport, the official weather station for the capital. July is Mexico City's rainy season, with afternoon thunderstorms common, though temperatures typically peak before precipitation arrives. The 0% crowd probability suggests traders are either confident in a specific temperature range or the market lacks sufficient liquidity to establish baseline odds.

Historical July data from Benito Juárez shows daily highs typically range between 24–28°C, with extremes occasionally reaching 30°C during particularly dry spells. The airport's elevation at 2,250 metres moderates temperatures compared to lower-altitude Mexican cities. Comparable prediction markets on weather platforms like Kalshi and Betfair have shown that temperature markets often concentrate liquidity around the most probable 2–3°C bands, leaving tail outcomes underpriced. Polymarket's fee structure (2% taker fee versus Kalshi's variable fees) affects how traders price uncertainty in narrow ranges, whilst Smarkets' commission model rewards longer-term positions differently.

Traders should monitor the Southern Oscillation Index and Atlantic hurricane activity in early July, as both influence Mexico City's weather patterns. The Mexican meteorological service (Servicio Meteorológico Nacional) issues monthly forecasts in June that typically refine expectations for July conditions. Settlement occurs at 12:00 UTC on 24 July, giving traders access to morning weather reports but requiring positions before afternoon thunderstorm development becomes visible.
