Data details: about this forecast

Weather values come from MET Norway (Norwegian Meteorological Institute) location forecasts, collected by Skymory and served from our own pages. They are model forecasts for this city’s coordinates, not observations from a weather station.

Forecast valid time: Oct 02 03:00 AST (local time).
Source updated by MET Norway: 2026-10-02T01:20:16Z.
Page generated from a snapshot with data state FRESH and source age 6.5 hours at generation.
Provider cadence is preserved: samples can be hourly or sparser, and probability, visibility and surface pressure are not shown because they are unavailable.
Daily ranges and wind maxima use the available samples and are approximate; rain totals use only complete, non-overlapping intervals.
