Daily ranges use available forecast samples. Today covers the remaining forecast period. The final day may be partial. Longer range forecasts use wider time intervals.

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 Costa Mesa (America/Los_Angeles).

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.
