Questions about this forecast

Is this a measured current temperature?

No. The large temperature is the nearest available forecast model value from MET Norway, not a reading from a weather station. The update time is shown beneath it.

Why does today show a small temperature range?

Today covers only the remaining hours of the day. Earlier temperatures are not reconstructed, so an evening visit shows a narrower range.

Which time zone do the times use?

All times on this page are local to St. Catharines (America/Toronto).

Can I change the units or save this place?

Choose °C or °F at the top of any page. Select Save beside the place name to keep it under My places in this browser. Neither needs an account.
