Cycling has a wider comfortable temperature band than running because the airflow you generate does most of the cooling for you. The best range is 15 to 24 degrees Celsius, and riders tolerate the upper end far better on the road than on a climb, where speed drops and the cooling effect disappears exactly when the effort peaks. That is the key asymmetry: a 28 degree day is pleasant on rolling terrain and brutal on a sustained ascent. On descents the equation inverts completely, since a 40 kilometre per hour descent at 12 degrees produces a wind chill closer to 3 degrees, which is why a packable gilet outperforms almost any other piece of kit. Wind is the dominant variable for cyclists in a way it is not for other activities. A 25 kilometre per hour headwind can cost 20 to 30 percent of your speed at constant power, and crosswind gusts above 45 kilometres per hour are a handling and safety issue on exposed roads and bridges, especially with deep-section wheels. Rain matters less for the wet than for braking distance, cornering grip and, most of all, visibility to drivers — the first ten minutes of rain after a dry spell is the most dangerous window as oil lifts off the road surface. Plan the route around the wind direction, and the temperature usually takes care of itself.
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.
