Los Angeles, with its Mediterranean climate, is sunny all year round, so even in December, daytime temperatures can still reach around 68 degrees Fahrenheit, much like summer. However, the temperature difference between day and night is significant and it's necessary to adjust clothing accordingly. Moreover, compared to summer, there's usually a bit more rain during this period.
