How run scores work
Every hour in the 7-day forecast gets a score from 0 to 100, based on five weather factors. The closer each one is to ideal, the higher the score.
What goes into a score
| Factor | Ideal | Counts for |
|---|---|---|
| Temperature | 4°C to 15°C | 30% |
| Rain chance | 20% or less, 0.5 mm or less | 25% |
| Wind | 20 km/h or less | 20% |
| Humidity | Dew point 13°C or less | 15% |
| Air quality | AQI 50 or less | 10% |
- Humidity is scored on dew point, which shows how muggy the air is at any temperature.
- Rain caps the score at 10 when the chance is above 70% with more than 0.5 mm forecast, or when 4 mm or more is forecast at any chance.
- Above AQI 100, air quality lowers the highest score an hour can reach, down to 10 at AQI 150.
- Above 35°C, below -25°C, or with wind above 70 km/h, the score is capped at 10 on every profile.
- When temperature, wind or humidity is as bad as it gets for your profile, the score can't go above 59, or 39 if two of them are.
