Highest temperature in San Francisco on June 15?

What you need to know

This market is asking: on June 15, 2026, what will the hottest moment of the day feel like at San Francisco's main airport? The temperature is split into ranges — roughly cool (68–69°F), mild (70–71°F), or a touch warmer (72–73°F). Those translate to about 20–23°C. A 'Yes' for any range means the peak thermometer reading that day fell inside those two degrees. Only one range wins, whichever one contains the single highest reading of the day. After June 15, 2026 ends, the market looks up the official peak temperature recorded at San Francisco International Airport (station KSFO) on Weather Underground. Whatever whole-degree Fahrenheit number appears as the day's high — say, 71°F — determines the winning range (in this case, 70–71°F). One important detail: the reading must be in whole degrees, no decimals. Any last-minute corrections to the data are accepted until the first reading of June 16 is published, after which the number is locked in. The two news items provided — a helicopter collision in Brazil and a plane crash in Missouri — have no connection to San Francisco weather. There is no relevant recent news to point to here. What would actually matter to watch for is any extended weather forecast for the San Francisco Bay Area as June 15 approaches, particularly whether a marine layer or inland heat pattern is expected. San Francisco's weather in June is genuinely tricky to pin down. The city sits between cold ocean air and warm inland heat, and a single shift in wind direction can swing the daily high by 10°F or more. The airport is especially sensitive to this — it sits on the bay's edge, catching fog some days and not others. The market's top two ranges (70–71°F and 72–73°F) together cover about two-thirds of current odds, but the spread across three close ranges reflects how real the day-to-day variability is.
