Los Angeles' October weather is more or less a continuation of a summer-like climate. October's average high of 79.0 degrees Fahrenheit (F) just misses June's average high of 79.5 degrees F. The average monthly precipitation is 0.37 inches, which is slightly more rainfall than in July, the city's driest month at .01 inches.
Anticipate the chance of more rain during November, as Los Angeles makes its seasonal shift to winter. Early storms and off-coast hurricanes account for the month's rainfall. November marks the beginning of the rainy season in L.A., which receives an average of 1.05 inches throughout the month. Average highs reach a comfortable 73.2 degrees, which makes Los Angeles a popular destination for those suffering winter doldrums from elsewhere in the United States.
Although Los Angeles is usually associated with continuous sunny, warm weather year-round, the truth is that some months, t-shirts and shorts may not be the best clothing. October's average low temperature is a somewhat cool 59.9 degrees F, and by November dips to 52.6 degrees. A day at the beach may be pleasant in shorts, but be prepared for nighttime temperatures by packing a light sweater or jacket, long-sleeve shirts and pants. Packing an umbrella, especially in November, is also important when braving pesky storms.
Temperatures may vary by as much as 20 degrees from Los Angeles' San Fernando or San Gabriel valleys to the city's coast. Pacific breezes help to cool down regions near the beach during warm months. In a sense, they act as L.A's "air conditioner," providing a cold blast for otherwise balmy regions.
