ANN  33.99″   (+19,08″, 228% of the \u201cnormal\u201d of 14.91 for the period 2000 to 2022)<\/p>\n\n\n\n

Most notable for 2023 at Westlake Village was the rain amount of 33.99\u201d, which is close to 19 inches greater than the 22-year average of about 15 inches.  Previous highest calendar year amount at Westlake Village since 2000 was 29.12\u201d in 2005. <\/p>\n\n\n\n

The first half of the year was especially cool and cloudy.  Both March and June had average maximums of 10 degrees below long-term averages, which is quite unusual.   The cool weather was due in large part to an above-normal number of storm systems affecting Southern California, plus cooler-than-normal sea-surface temperatures along our nearby coast combined with more onshore flow than average.<\/p>\n\n\n\n

The most notable weather event of the year was the big rain event around August 20, courtesy of hurricane and tropical storm Hilary.  Hilary moved northward into Imperial and San Diego counties and caused plenty of flooding problems in desert areas.  Westlake Village had 3.00\u201d of rain on August 20.  The previous wettest day during August since 2000 was 0.04\u201d in August 2005.  The event compared closely to the mid-August rain event with ex-hurricane Doreen in mid-August 1977.  Doreen dumped about 2.5 inches of rain into my gage in Woodland Hills around Aug 16\/17 in 1977.<\/p>\n\n\n\n

Other than Hilary, summer weather was quite free from tropical and subtropical shower activity.  September was unusually cool with an average max temp of only 80F.<\/p>\n\n\n\n

And, of course, the winter months of J\/F\/M were exceptionally cool and wet, with nearly 26 inches of rain!<\/p>\n","protected":false},"excerpt":{"rendered":"
