Highest temperature in San Francisco on July 22?: how this market works

What you need to know

This market is asking: on July 22, 2026, what will the hottest reading of the day be at San Francisco International Airport? The answer is a temperature range, not a single number. A Yes on '74-75°F' means the thermometer peaked somewhere in that two-degree window that day, while a Yes on a different range means the peak landed there instead. Only one range wins. After July 22, 2026 ends, someone checks the Weather Underground page for San Francisco International Airport (station KSFO) and reads the single highest temperature recorded that day, rounded to a whole degree Fahrenheit. Whatever two-degree range contains that number is the winner. The market waits until the first data point for July 23 appears before settling, and only temperature readings published before that cutoff count. No relevant weather news was provided for this market. The one headline listed appears unrelated to San Francisco temperatures. To follow this market, the useful thing to watch would be extended forecasts for the San Francisco Bay Area as July 22, 2026 approaches, along with any reports of unusual heat events or marine layer patterns affecting the region. San Francisco's summer temperatures are notoriously hard to pin down even a day in advance. The city sits at the edge of the Pacific, and a strong marine layer can keep highs in the low 60s while inland areas hit 100°F. SFO airport specifically sits near the bay and is sensitive to fog burn-off timing. The three leading ranges cover 72°F to 77°F and are fairly close in odds, which reflects genuine spread in historical July highs for that location.
