    In January, the west coast state of California is mild and wet. At this time of year, temperatures vary depending on which part of the state you’re visiting, with cooler, wetter weather in the north and slightly warmer temperatures in the south. Although showers are common in January, there’s also plenty of sunshine, making this a good month to visit if you want to explore California away from the high season crowds.


    In Los Angeles, average daytime temperatures in January hover around 13°C, with highs of 18°C in the peak of the day and lows of 8°C at night. San Francisco is cooler at this time of year, with averages of 10°C and lows of 7°C after dark. With mild afternoons and cool evenings, you’ll need to pack for all temperatures. Around 80mm of rain is expected during the month in Los Angeles, and 120mm in San Francisco, so it’s worth bringing a light waterproof jacket in case of showers.
