Highest temperature in San Francisco on June 30?

Platform comparison

Market context

The real-world event is the daily high temperature recorded at San Francisco International Airport on 30 June 2026, a metric that historically clusters between 68°F and 71°F, rarely exceeding 80°F. Current crowd-implied probability of 0% for any outcome above the lowest range suggests a mispricing, as June in San Francisco is typically mild, with the airport’s average high rising only 3°F across the month.

Historical precedent shows that even record-breaking heat at KSFO, such as the 91°F spike in recent years, remains an outlier rather than a norm, while the first half of summer 2026 was notably cool, with average maxima just 67.6°F through mid-July. This aligns with BBC Weather’s current forecast of 67°F for 30 June, reinforcing that extreme highs are improbable but not impossible, making the 0% probability for higher ranges statistically fragile.

Traders should monitor Wunderground’s hourly updates for 30 June, particularly any sudden shifts in wind direction or cloud cover, as these directly influence temperature peaks. A recent KRON4 report on record-breaking heat at KSFO highlights that while 91°F is possible, it requires specific atmospheric conditions unlikely to recur without clear precursors. Watch for National Weather Service advisories on marine layer breakdown, which could trigger unexpected warming.

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.

Who can trade Eurovision markets?

Polymarket is globally accessible but geo-blocked in select jurisdictions — traders there use broker frontends with a different geo footprint to reach the order book. Eurovision markets have strong European liquidity; German/Austrian/Swiss flow often drives consensus.

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.

Is entertainment trading worth the effort?

Niche, but lucrative for experts. Award markets have fewer informed traders than political markets; combining industry expertise (film, music) with active research often surfaces mispricings. Volume cap: large bets move the market.
