How GoodDayTo judges cycling weather
Cycling is especially sensitive to wind and wet weather. A forecast that looks acceptable for a short walk may be much less comfortable on an exposed bike route. GoodDayTo weights rain, sustained wind and gusts more strongly for cycling and searches the hourly forecast for a better window.
- Rain probability
- Wind speed and gusts
- Apparent temperature
- Daylight
- UV
🌞 Make the most of the good window
- Check the wind direction too when planning a long out-and-back route.
- Wet roads can increase stopping distance and reduce grip.
- Use lights and visible clothing whenever daylight is limited.
Why the best cycling window can change quickly
Wind matters more on a bicycle than it does for many everyday outdoor activities. A modest headwind can add substantial effort over a long route, while gusty crosswinds can make exposed roads unpleasant even when the temperature is ideal. GoodDayTo therefore gives sustained wind and gusts significant weight alongside rain, apparent temperature and daylight.
If the score says WAIT, compare the later window with your route direction. A wind that is awkward on an exposed out-and-back ride may be much less important on a sheltered urban route. After rain, allow for wet braking surfaces, spray and reduced grip even if precipitation has already stopped.
What the cycling score cannot know
GoodDayTo does not know your route, traffic, elevation, road surface, tyre choice or whether cycle paths have local ice, debris or standing water. It also cannot determine safe visibility from your clothing and lights. Use the score to choose better weather; use local road knowledge and normal cycling judgement to decide whether the route itself is suitable.
What the score means
GO means the weather signals we can measure look favourable. WAIT means conditions are mixed and a better hour may be nearby. NOT TODAY means the forecast currently contains enough unfavourable signals that this activity is unlikely to be a good weather choice. These are planning recommendations, not safety clearances.
Frequently asked questions
Why is wind weighted strongly for cycling?
Because wind can materially affect effort, handling and comfort, especially on exposed routes.
Can I use the score for commuting?
Yes as a weather guide, but route traffic, road condition and your equipment are separate considerations.
Does light rain automatically mean NOT TODAY?
No. The score falls progressively with rain probability and amount rather than treating every shower risk the same.
