Highest temperature in Houston on August 3?

Platform comparison

Market context

Houston’s highest temperature on 3 August will be set by the William P. Hobby Airport reading that Wunderground records for that day, so the market is really a one-day outcome on a single station rather than a broader city average. In a market like this, the main issue is not direction but threshold: once a hot August day is broadly expected, the price should move on whether forecasts suggest a routine 90s Fahrenheit afternoon or a more extreme run into the upper 90s or beyond. Houston’s August climatology is firmly hot, with typical daily highs around the mid-80s to upper-80s Fahrenheit and long-run August highs often near 88°F or 95°F depending on the source used for the city or airport climate page.[1][5][9][15]

Recent market framing suggests traders are treating 95°F as an important pivot, which mirrors how weather markets often cluster around rounded temperature bands rather than exact readings.[16] That matters because Wunderground resolves to the *highest* observed temperature for the day at Hobby Airport, so a brief late-afternoon peak can decide the contract even if the rest of the day is slightly cooler. The broad consensus from Houston August weather pages is that the city regularly sees daytime highs around 33°C to 35°C, with very high heat and humidity, which supports a baseline expectation for a hot reading even before any short-term forecast nuance is added.[4][17][9]

For the final move, traders should watch the local forecast updates closest to the settlement date, especially any heat ridge strengthening over southeast Texas, cloud cover or rain chances, and whether official hourly forecasts imply a sustained peak rather than a short-lived spike. Sources covering 3 August 2026 already point to sunny, hot conditions with highs around 37°C in Houston, which would normally keep the upper-temperature bands in play if that pattern holds at Hobby Airport.[3][8] Because this market settles on station data rather than a citywide headline forecast, small shifts in wind, moisture and storm timing can matter more than the broader “hot day” narrative.

FAQ

Which entertainment markets are available?

Oscars / Academy Awards (Best Picture, Best Director, Best Actor/Actress), Eurovision Song Contest, Emmy Awards, Grammy Awards, Golden Globes, plus reality-TV outcomes (Bachelor, Survivor). Volume usually sits in the five- to six-figure range per market.

How accurate are award predictions?

Variable. Industry-predictable awards (Oscar Best Picture) have high market accuracy (Brier ~0.15). Reality-TV outcomes with small markets carry more noise. Eurovision is notorious for market upsets due to bloc voting.

What was the top Oscar 2025 market?

Best Picture, with ~$2.8M volume on Polymarket. "Anora" started as an underdog at ~8% and closed at ~62% before the ceremony — the biggest single Oscar market swing since 2019.

How are reality-TV outcomes verified?

UMA Oracle uses the official show website or producer statement as the resolution source. Very narrowly defined markets (e.g. "Will X be voted off the island?") rely on the official show notes.

Are there politics-entertainment crossover markets?

Yes — e.g. "Will X be parodied on SNL?", "Who will host the next Oscars?". These have thinner liquidity but offer alpha for traders who read pop-culture and political worlds together.
