Highest temperature in San Francisco on July 14?

Platform comparison

Market context

The underlying event is the peak daytime heat recorded at San Francisco International Airport on 14 July 2026, measured in degrees Fahrenheit. Historical July data for KSFO typically shows maximums between 70°F and 80°F, with extreme heatwaves occasionally pushing temperatures higher. The current crowd-implied probability of 0% for a “YES” outcome (likely meaning a temperature outside the expected range) aligns with the market’s strong consensus that 78–79°F is the most probable result, holding 93% of implied probability [1]. This distribution suggests traders view a significant deviation from this range as highly unlikely based on seasonal norms and recent climate patterns.

Traders should monitor official National Weather Service forecasts for the Bay Area in the weeks leading into mid-July 2026, as well as any emerging heatwave alerts from California’s Office of Emergency Services. A recent analysis from the California Department of Water Resources highlights that prolonged marine layer disruptions can elevate coastal temperatures beyond typical July averages, a factor that could shift probabilities if confirmed [1]. No major regulatory announcements are expected to directly alter weather outcomes, but the market’s settlement depends entirely on Wunderground’s recorded data for KSFO, making data integrity the sole operational dependency.

From a regulatory standpoint, German GlüStV implications mean that users in Germany must comply with strict licensing and KYC thresholds for prediction markets, while US CFTC reach extends oversight to any platform offering contracts on US-based events. The “no-KYC up to $1,500” feature enhances accessibility for international traders, allowing participation without identity verification for smaller positions, though larger trades will trigger compliance checks. This structure balances regulatory adherence with market fluidity, ensuring the San Francisco temperature market remains accessible while staying within legal boundaries.
