Frequently Asked Questions

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.

Where does the data come from? Forecasts come from Open-Meteo, which blends the ECMWF, GFS and ICON numerical weather models, and sunrise, sunset, twilight and moon times are calculated on-site from each location's coordinates in its own timezone. How often does it update? Model runs land several times a day and the site fetches the latest available run on each page load, so a score can shift through the day. How is the Weather Score calculated? It is a 0-100 composite weighting temperature comfort at 40 percent, rain risk at 30 percent, wind at 20 percent and the WMO weather code at 10 percent, with severe codes acting as absolute blocks and individual penalties capped so no single variable can collapse a verdict on its own. Every formula is published on the methodology page. How far ahead can I trust the forecast? Days one to three are reliable enough to book on, days four and five show direction, and beyond seven days the honest answer is low confidence, which is why our recommendations cap there. Why does a 90 percent illuminated moon show poor visibility? Because illumination is not the same as visibility — if the moon is below the horizon during your evening, or cloud covers the window when it is up, the phase is irrelevant. Which locations are covered? Cities, resorts and natural landmarks worldwide, with over 11 million searchable locations via geocoding. Do I need an account? No. Is my data sold? No.

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. Forecast data is Open-Meteo; solar and lunar values are computed for this location's own coordinates and time zone. Full details on the methodology page.
