Santa Barbara's all-time extremes tell the story of a city that rarely gets pushed to the edge. The thermometer has hit 108° (September 1913) and dipped to 20° (January 1949), but those are true outliers — this is a place where a 65° January afternoon is just a Tuesday. The wettest single day on record dumped 8 inches in January 1995.
Santa Barbara's famous for its near-flatline climate — monthly highs only swing from 65° in January to a peak of 78° in late August and early September. If you want the warmest beach days, aim for late summer; if you're rain-averse, avoid February, when weekly precipitation averages over an inch. Honestly, though, any month here is a reasonable gamble.
