SGEN · Climate normals 1991-2020

Period 1991-2020

Twelve monthly averages for SGEN, computed from NOAA GSOD observations over 1991-2020. These are typical values for each month — averages, not a forecast and not a substitute for the current METAR/TAF. A single month can differ from its normal by several degrees and still be normal.

Wet day = day with at least 0.25 mm of precipitation. The annual row is the mean of the twelve monthly means and the sum of the twelve monthly totals, so it can be reproduced from the table. † Mean max and mean min come from GSOD's daily extremes over the synoptic observations of each day, not from a calendar-day extreme: they read roughly 0.5–1.5 °C wider than the official normals of the same station. The mean temperature and the precipitation are unaffected.

Compared with our own archive

station_month · METAR observations

The observed archive is too young to compare. We have 0 complete months of our own observations for SGEN (from 2026-10-29); 3 are needed before a monthly comparison means anything.

No comparison is shown rather than one drawn from a handful of days. The normals above come from NOAA GSOD and do not depend on our archive.
