Pronóstico: Highest temperature in San Francisco on August 13?

Platform comparison

Market context

San Francisco's weather on 13 August 2026 will determine the settlement of this market, with resolution hinging on the highest temperature recorded at the airport weather station that day. The distinction between the Daily Observations table and the Day High & Low summary section matters operationally; traders should verify which source Weather Underground prioritises in practice, as historical discrepancies between the two have occasionally affected similar markets.

August temperatures at San Francisco International Airport typically range between 65–75°F, with the historical high for mid-August around 85°F. The city's maritime climate produces remarkably consistent summer conditions; the 30-year average high for 13 August sits near 72°F. Extreme heat events above 90°F occur infrequently in this location—roughly once every five to seven years during the broader summer season—making elevated temperature ranges statistical outliers rather than baseline expectations.

Traders monitoring this market should track Pacific weather patterns in early August 2026, particularly high-pressure systems that could drive inland heat penetration toward coastal areas. The National Weather Service Bay Area forecast issued in the week preceding 13 August will provide the most actionable signal. Marine layer strength and timing remain the primary variable; morning fog persistence typically caps afternoon highs, whilst clear conditions allow greater warming. Any atmospheric river activity or unusual ridge positioning in the preceding week would shift probability materially.

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.
