January Brings Rain and Cool Weather to Los Angeles
January in Los Angeles is characterized by cooler temperatures, increased rainfall, and diverse microclimates. The month often ranks among the wettest of the year, with average daytime highs ranging from 68°F to 72°F (20°C to 23°C) and nighttime lows between 45°F and 50°F (7°C to 11°C). Rainfall contributes significantly to the city's annual precipitation, influenced by North Pacific weather systems, jet stream patterns, and occasional atmospheric rivers.

Santa Ana winds may also bring unseasonable warmth and fire risks to certain areas.
