North Coast Drainage

Wettest division in the state; winter-dominant.

NCEI DIVISION1CALIFORNIA

Climate divisions are broad reporting areas. Golden State Weather's eighteen terrain regions nest inside them imperfectly but usefully: the division supplies the statewide frame, while the region explains which range, gap, basin or coastline makes one station differ from the next.

These figures summarize the named NOAA stations attached to this site's places inside the division. They are useful for comparing its internal spread, but they are not NCEI's official gridded or area-weighted divisional series. Mountains and cities are intentionally over-represented because this is a terrain atlas.

The measured record for this division

NOAA computes an official area-weighted monthly series for every climate division, back to 1895. Our companion site carries all of it — the warming rate, the wettest and driest water years, the drought ledger and the ENSO correlation — on Golden State Climate. Free, ungated, and recomputed from NCEI's published tables.
