I’ve lived here almost 12 years and I’ve only seen it rain in July a handful of times. Two of those times were yesterday. And last night, I woke up to this:
Never, ever ever ever, ever seen a real rainstorm like that in July. Turns out, it was extremely rare, according to the awesome Nathan Masters, a case of monsoonal moisture leaking in from the deserts:
Dry summers are supposed to be one of the perks of living in Los Angeles. Ninety-two percent of precipitation falls between the months of November and April. But while it’s rare, summer rain does sometimes dampen L.A.’s summertime fun, driving Angelenos into their storage closets in search of an umbrella.
Aside from marine layer drizzle, the main source of warm season rain is monsoonal moisture leaking from the interior deserts onto the coastal plain. Thunder and lightning often accompany the rainfall. L.A.’s downtown weather station recorded its one-day rainfall record for July on July 14, 1886, when 0.24 inches fell. August typically brings more monsoonal rain than July; that month’s record is 2.06 inches on August 17, 1977.
Finally, here’s a little story about how living in LA has made me obsessed with the weather. IN CASE YOU DIDN’T NOTICE.
Update: We broke a record for rain on July 11, a date which has only seen rain three times! OBSESSED!
