Chico sits in California's Sacramento Valley, giving it that classic Mediterranean feel, hot, dry summers and mild, wet winters. What catches most visitors off guard is how dramatically the temperature swings between seasons, with summer afternoons that'll have you hunting shade and winter mornings that demand a proper jacket. The town gets most of its rain between November and March, typically in gentle drizzles rather than downpours, though every few years a proper storm rolls through. Spring and fall deliver that sweet spot weather-wise, with warm days giving way to cool nights good for outdoor dining or catching a show at the Sierra Nevada brewery.
