Understand this market
This market is asking: how hot will San Francisco get on July 13, 2026? Specifically, it's asking which 2-degree temperature band will contain the single highest temperature reading of the day — so if the peak temperature is 79°F, the '78–79°F' outcome wins. The location is San Francisco International Airport (SFO), which sits a few miles south of the city center near the bay. July is typically San Francisco's foggier, cooler summer month, so the ranges here — mid-to-high 70s and low 80s — reflect that mild coastal climate.
