Los Angeles, CA: average weather by month
NOAA 1991–2020 climate normals at the LOS ANGELES INTL AP station, read through NOAA's Regional Climate Centers' ACIS service. Every column below is the station's own average for that month over that 30-year period — not a forecast. The rainfall figures are NOAA's precipitation normal, so they count rain plus melted snow (and any other frozen precipitation, as water), not rain alone.

Months within our comfort range
We set one fixed, objective threshold ourselves — average high between 65°F and 80°F, and average rainfall under 2 in — and check each of the twelve rows against it. This is not a claim that any other month is bad, and not our judgment of which month suits any trip; it is just which rows on the table above clear the stated numbers. See how we set this threshold.
March, April, May, June, July, August, September, October, November are the months at Los Angeles that clear both parts of the threshold: March 66.1°F / 1.73 in; April 68.1°F / 0.6 in; May 69.5°F / 0.28 in; June 72°F / 0.08 in; July 75.1°F / 0.04 in; August 76.7°F / 0 in; September 76.5°F / 0.11 in; October 74.4°F / 0.49 in; November 70.9°F / 0.82 in.

About the station
These normals are read at a single NOAA/NWS station, LOS ANGELES INTL AP (station ID 23174), not averaged across the whole metro area. A different station nearby — higher ground, closer to water, further inland — can read noticeably different numbers, especially for rain. Run this station's ACIS query yourself.
What this page adds
A search for "los angeles weather by month" mostly returns a day-by-day forecast calendar (useful only for the next two weeks) or a local weather office page built for a different question. This page puts all twelve months of the 1991–2020 average on one screen, in both °F/°C and inches/mm, names the exact station behind the numbers, and sets it next to a few nearby cities so the difference is visible at a glance.
