Why runners here should watch dew point, not just temperature
Air temperature alone under-sells a humid day. Dew point measures how much moisture the air is holding, and the higher it climbs, the less evaporative cooling you get from sweat — so 75°F (24°C) air with a 70°F (21°C) dew point cools a runner far less than 75°F with a 50°F (10°C) dew point. Wyndo's run profile scores heat and humidity together, so the verdict above already accounts for the combination at the San Francisco reference point.
When is the best time to run in San Francisco?
It changes day to day. In San Francisco, CA, early morning is often the coolest part of the day in warm months (though dew point can still be high then), and city streets can hold heat well after sunset — heat, dew point, wind, rain, and air quality can each move the answer.
