Winters are cool to cold. Usually it gets to around 30 degrees in December, but snow is extremely rare. Spring is usually rainy but mild (highs in mid-50s and 60s). Summer can be extremely hot. Most days are in the high 80s to mid 90s, but it's not uncommon for temps to reach mid 100s for at least a week or so in the summer. Fall is the best season. Cool weather and usually sunny days (occassionally foggy mornings and evenings).
