Specialist tools for Rio de Janeiro
Sources and method
Forecast values (temperature, feels-like, precipitation probability and amount, wind, gusts, cloud, UV, weather code) are model output from the Open-Meteo forecast API, requested for Rio de Janeiro's coordinates in its local time zone each time this page is opened. Sunrise, sunset, day length and golden-hour windows are calculated from solar geometry for the same coordinates. Weather Score and activity scores are deterministic formulas documented on the methodology page. This page does not show historical climate averages: no verified monthly climate dataset is used on this site.
