Frequently asked questions
What time is it in Rotterdam while I read this?
Rotterdam uses Europe/Amsterdam, currently UTC+2 (CEST). The current local time, with seconds, is on the Rotterdam 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 Rotterdam. 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 Rotterdam'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 Rotterdam through the year?
Between about 7h 45m and 16h 43m. At 51.9° this is a mid-latitude location in the northern hemisphere, so the swing between the solstices is pronounced.
