It's California—land of the unpredictable, bipolar weather. Depending on the season, it could be cold and storming one moment and sunny the next. Overall, though, expect blue skies and, at times, extreme heat. A typical California day involves a chilly morning, a hot day, and a cool evening.
On most summer days, the heat starts to set in as early as 7 or 8 a.m. The weather makes it great for enjoying a day in the school pool or taking walks around campus. During the fall, the sun still shines, and the weather is warm until about November, when the chill starts to set in. Rain will fall, though not too much, but you can expect at least three inches of rain in December. Then spring starts to shy in, which means some spring showers, but besides that the sun heats everything up. The weather is not hard to predict. It's mostly sunny, but California will throw the occasional curve ball.
