Planning guidance, not a guarantee. Conditions can vary within a forecast area. Follow current official instructions and use local judgment for your route, equipment, health, and surroundings.
Match the window to your route
Include the return leg in your duration. If an hour is too long for the available window, compare a shorter loop rather than choosing a start that leaves the return outside the forecast window.
Check what the forecast cannot see
Before choosing a route, check its hills, crossings, lighting, shade, and surface condition. A city forecast cannot tell you whether a particular sidewalk is icy or a path is accessible.
Put the plan into the forecast
Start with the 45-minute default, then adjust it to your actual outing. Check official alerts and the reasons beside the recommended window before leaving.
Route grade, traffic, surface condition, mobility needs, and shade remain outside the forecast.
