With over 300+ days of sun, “Sunshine You Can Count On,” isn’t just a Tri-Valley motto, it’s a way of life. Though the seasons are on the mild side in the San Francisco Bay Area, you are promised four distinct seasons in the Tri-Valley. From colors changing to nighttime temperatures, every season of the year has unique characteristics.
As the leaves are changing colors and temperatures are averaging in the 70s, visitors will experience the beginnings of rain. Autumn is an incredible time to visit the Tri-Valley, our vineyards are showing orange and red hues and the leaves are falling in our parks. You should still expect warm days, but keep in mind the evenings are cooling down, so you may need a light sweater.
Days are shorter and holiday lights are up in full force. Visitors will experience rainfall on occasion, but will continue to enjoy our outdoor venues such as the San Francisco Outlets, Del Valle Regional Park and our historic Wine Country. By the winter months, our rolling hills have turned a beautifully bright green. You should expect mid-low 60s during the day with temperatures cooling into the 40s at night.
Springtime is the season to blossom in the Tri-Valley. Flowers bloom, our vineyards start to bud and our hills turn to the iconic golden coloring that represents the state of California. Visitors should expect temperatures to begin rising in May, while nights remain cool.
Remember your sunscreen! Although Livermore feels the coastal breeze through their valley, regional temperatures average in the 90s. You’ll find locals in our region’s family-friendly fountains and lakes to cool down while enjoying the sunshine. And let’s not forget al fresco dining, the Tri-Valley’s warm summer nights are perfect for evening on the patio.
