Dew point is the real story in Rome
Dew point — not the thermometer — decides how hard a run feels. The muggiest month in Rome is August, when the typical dew point reaches 65°F (18°C) (sticky). At that point sweat stops evaporating efficiently, so even a moderate temperature feels brutal. Compare that with December, the easiest month, when dew points sit near 45°F and the same effort feels far lighter. The hour-by-hour scores above already fold this in.

What the calculator scores
The Run Score is not a single reading dressed up. Eight weather signals are weighted by how much each one actually changes a run, then combined into one decision.
Temperature
Performance peaks near 50–54°F. Every degree above that taxes your cooling system 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
Headwinds cost pace and gusts break rhythm. The model weighs sustained speed and direction, not just the headline number.
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 give back today so your effort — not the clock — stays honest.

December. Typical daytime Run Scores average 95 (Great), the best of the year, with temperatures around 50°F (10°C).
When is it too hot to run in Rome?
July is the toughest month — typical temperatures near 82°F (28°C) with noticeable dew points around 64°F. On days like that, run in the 6–8 AM window and ease off the pace.
What time of day is best for running in Rome?

When is the best time to run in Rome?

Run the calculator above and it returns today's highest-scoring window for Rome — usually early morning or evening when heat and dew point are lowest. Tap any hour to see the full breakdown.
What is a good Run Score?
Scores run 0–100. 97+ is Perfect, 80–96 is Great — conditions are actively working in your favour. 65–79 (Good) is solid. 45–64 (Mixed) means at least one factor — usually heat or dew point — is taxing 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.
How is this different from a normal weather app?
A weather app tells you the conditions. This calculator translates them into a running decision: a single score, the best hour to head out, and a concrete pace adjustment in seconds per mile — using the same scoring engine that powers the RunWeather app.
Is the running weather calculator free?
Yes. The calculator is completely free to use, with no account required. The RunWeather app adds Strava sync, multi-day planning, and personalized heat acclimation on top of the same model.
