Frequently asked questions
What time is it in Porto Alegre while I read this?
Porto Alegre uses America/Sao_Paulo, currently UTC-3 (BRT). The current local time, with seconds, is on the Porto Alegre time page — worth checking before you call, since a forecast for "tomorrow" there may still be today where you are.
Where does this weather data come from?
Open-Meteo, requested by your browser when you open this page. It needs no account or API key, so nothing about you is sent to us or to them beyond the coordinates of Porto Alegre. Readings are cached in your browser for 30 minutes and always labelled with the time they were taken.
Why are sunrise and sunset here but the temperature has to load?
Because they are different kinds of fact. Sunrise and sunset follow from Porto Alegre's latitude and longitude and the date, so we compute them locally and they are correct whether or not anything loads. Temperature is an observation — it has to come from someone measuring it, which means a network request that can fail.
How much does daylight vary in Porto Alegre through the year?
Between about 10h 13m and 14h 05m. At 30.0° this is a subtropical location in the southern hemisphere, so the swing between the solstices is pronounced.
