Turn sky and weather data into a simple pre-trip read: when the light is good, when the night is dark, and when the coast or outdoors will feel better.
Work through three questions before leaving: what are tonight's conditions, what can you photograph, and what is the backup if conditions deteriorate?
Different activities react to weather differently. Running cares about heat and UV, hiking about rain and wind, and coastal plans about tide too.
Weather
No rain does not always mean comfortable. High apparent temperature or strong wind can reduce activity quality, so the score compares these conditions by time slot.
Sun
UV often peaks around midday. Running, family outings, and long walks may be better in the morning, evening, or lower-UV windows.
Coast
Coastal activities also depend on the tide station. Tide turns, wind, and rain together affect safety and comfort.
The same time slot can feel very different depending on the activity. Choose the activity first so the score matches the experience.
Running
Running is highly affected by apparent temperature. Short runs tolerate ordinary conditions, but long runs need cooler, lower-UV, stable weather.
Hiking
Mountain weather changes quickly. Rain, wind, and cloud can affect safety. A high score does not replace trail status and official alerts.
Coast
Fishing, surfing, and intertidal plans cannot rely only on sunny weather. If tide or wind is wrong, a land-based backup is often safer.
No. The score ranks time slots using weather, UV, wind, rain, and tide data. Use it to narrow options, then check local conditions, route safety, and official warnings.
Weather becomes more reliable closer to the date. Use distant dates for daylight and Moon planning, then confirm with short-range forecasts before leaving.
City weather does not describe sea level. Surfing, fishing, and intertidal activities depend on tide, so a nearby tide station is needed.
