Pronóstico: Highest temperature in Houston on July 23?

Platform comparison

Market context

Houston’s peak temperature at William P. Hobby Airport on 23 July is decided by a single daytime reading, and in practice the market turns on whether the city gets a near-normal summer warm-up or an amplified heat spike. July in Houston is already hot: average highs are around 96°F, with humidity and frequent rainfall often muting extremes even when the air mass is warm.[2] That backdrop helps explain why a 0% crowd-implied chance for the lowest temperature bands is not inherently surprising if traders expect the day to finish well above the cooler bins.

For framing, the useful comparator is not whether Houston can be hot, but whether it can briefly push into the upper 90s or beyond. Past Houston weather data show highs around the mid-90s even on muggy days, with fog, light winds, and very high humidity features that can limit radiational cooling overnight but do little to prevent a strong afternoon peak once sunshine builds.[1] On that basis, the market is more sensitive to a modest shift in cloud cover, precipitation timing, or boundary-layer mixing than to any broad seasonal trend.

The key catalysts are the same ones that usually move an hourly temperature outcome: the latest forecast for cloud cover, the chance of afternoon showers or storms, and any heat advisory language from forecasters as the day develops. Because the settlement source is the William P. Hobby Airport station on Wunderground, traders should watch whether the official airport observation site posts a clean afternoon spike or gets capped by rain-cooled air. Early-morning conditions matter less than the 12:00–18:00 local window, when the day’s maximum is most likely to be set.

FAQ

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

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.
