Is it good to run in São Paulo in February?

It's runnable, but at least one factor (usually heat or dew point) is working against you. The typical daytime Run Score is 60 (Fair), with temperatures around 71°F (22°C) and sticky dew points. The best window is usually 6–8 AM.

How hot is it for running in São Paulo in February?

Typical temperatures average 71°F (22°C) (Warm) with dew points near 66°F. Dew point (not the thermometer) usually decides how hard the run feels.

What is a good Run Score?

Scores run 0–100. 80–100 is Great (97+ earns a gold star for near-perfect conditions). 65–79 (Good) is solid. 55–64 (Fair) or 45–54 (Tough) means at least one factor (usually heat or dew point) is slowing you. Below 45 (Poor), expect a noticeably harder effort or hold back for safety.

Why does dew point matter more than temperature?

Your body cools by evaporating sweat. When the dew point climbs above roughly 60°F, the air is too saturated for sweat to evaporate efficiently, so heat builds up even if the thermometer looks reasonable. That's why a 70°F muggy morning can feel harder than a dry 80°F afternoon.

What the calculator scores
Eight signals, weighted by how much each changes a run
Temperature. Performance peaks near 50–54°F. Every degree above that works your cooling system harder and slows the pace you can hold at the same effort.
Dew point. The real humidity signal. Above ~60°F dew point, sweat stops evaporating efficiently: the single biggest hidden driver of a hard summer run.
Wind. Sustained wind and gusts feed drag and thermal estimates. This public calculator uses a default route-exposure assumption because it does not know your running direction.
Heat stress. How hard heat, humidity, sun, and wind hit your body, combined into one number (wet-bulb globe temperature), the same metric race directors use to flag risk.
Solar exposure. Direct radiation on a shadeless route can feel far hotter than the air temperature. Cloud cover and sun angle are factored in.
Precipitation. Rain probability and intensity affect footing, comfort, and gear, weighted by how likely it is during your window.
Air quality. US AQI is folded in so sensitive runners get a clear signal when particulates make hard efforts a bad idea.
Pace adjustment. The output you actually use: how many seconds per mile to ease off today so your effort (not the clock) stays honest.
Enter your city. Search any city worldwide. RunWeather pulls the live local forecast: temperature, dew point, wind, sun, and air quality.
Get a 0–100 Run Score. One number that blends performance, safety, and experience (labeled Great, Good, Fair, Tough, or Poor) for the current hour.
