Conditions on this page are recalculated from the latest forecast every time it is opened, for the current date in the location's own time zone.
The optimal temperature for running is 10-15°C (50-59°F). This range allows efficient body heat dissipation without requiring excessive sweating or heavy insulation. For cycling, 10-20°C (50-68°F) is ideal due to the additional cooling effect from airflow. Slightly cooler temperatures work well because of the wind chill generated at cycling speeds. Wind dramatically affects cycling due to aerodynamic drag. Headwinds of 20-30 km/h create significant resistance, while winds above 40 km/h can be potentially dangerous. Plan routes to ride into headwinds when fresh. Ideal humidity for endurance exercise is 40-60%. Below 30%, dry air can irritate airways. Above 70%, cooling efficiency drops significantly as sweat cannot evaporate effectively. Master the art of weather-based training. Learn optimal conditions for cycling and running, understand how temperature and wind affect performance, and discover the best times to exercise outdoors. t just affect comfort — it directly impacts pace, safety, and training quality. Here. s conditions match your training goals before you lace up." primaryText="Check today. A 25°C "perfect day" can destroy your training if humidity hits 80% and wind gusts to 30 km/h. Conversely, a gloomy 12°C morning might be your best performance window all week. Weather doesn't just affect comfort — it directly impacts pace, safety, and training quality. Here's how to use it to your advantage. This isn't coincidence — your body generates 300-600 watts of heat during intense exercise, and cooler air dissipates it efficiently. Train in the "wrong" temperature and you're fighting physics. This means a 20 km/h headwind at cycling speed creates massively more resistance than the same wind for a runner. A headwind that a runner barely notices can turn a cycling workout into a grinding ordeal. Smart route planning: Start your ride heading into the wind when legs are fresh. Enjoy the tailwind home when you're tired. This single tactic transforms a frustrating ride into a good one. High humidity blocks your primary cooling mechanism (sweat evaporation), causing core temperature to rise even at moderate effort levels. Running in rain can be refreshing in warm weather. But cycling in rain requires real adjustments — braking distance doubles, painted road markings become ice-like, and visibility drops. The golden rule: Start cold. You should feel slightly underdressed in the first 5 minutes. If you're comfortable immediately, you'll overheat within 15 minutes.
Scores are capped by dealbreakers — heavy rain, dangerous wind, thick fog or hazardous UV pull a day down no matter how pleasant the rest of the numbers look.
