Winters Weather
Town • San Francisco Bay Area
Winters is a small farm town on Putah Creek at the western edge of the Sacramento Valley. It sits right where the creek comes out of the hills and onto the orchards and fields of Yolo County. Downtown sits beside the water, where a creekside nature park runs under the town's trestle bridge. West of town, Highway 128 follows Putah Creek up its canyon past a string of public creek access sites toward Lake Berryessa. That makes Winters the valley's doorway to the Blue Ridge country.

Winters is a valley town pressed up against the Coast Range, and it is farther from the Carquinez Strait than Fairfield or Vacaville. The delta breeze, cool air pulled inland from the bay, reaches Fairfield by mid-afternoon. It has a long way to travel across the valley floor to get here, so it tends to arrive late and weak. Summer afternoons in Winters are among the hottest in this part of Solano and Yolo counties.

What shapes Winters' weather
The hills just west of Winters shape its nights and mornings. On calm evenings, air cooled on the slopes can drain down the Putah Creek canyon and settle along the creek. Creekside spots can then feel noticeably fresher at dawn than open farmland a few miles east toward Davis.
Heat waves arrive on north or northeast winds sinking into the valley. The dry grass, oak, and manzanita on the hills west of town make fire weather a serious concern in late summer and fall. The Yolo-Solano air district says wildfire smoke affects its residents every year.
Winter storms bring most of the year's rain and raise Putah Creek. Lake Berryessa, the reservoir just west of Blue Ridge, provides flood control for the town. It also supplies water to the Solano cities to the south. On calm winter mornings, valley fog can settle over town.
Tips for visiting Winters
Hike Stebbins Cold Canyon at dawn in summer
The trails are open sunrise to sunset all year, but the Putah Creek Council warns of a significant risk of heat stroke in summer. Start early and carry plenty of water.
Cool off at the Putah Creek access sites
Five fishing access sites along Highway 128 west of town offer shade, trails, and direct creek access, with restrooms at sites 2 and 4.
Walk the creek right in town
The Winters Putah Creek Nature Park has a paved, bike-friendly trail plus a rougher path along the water. Dogs are welcome, but keep them close during salmon spawning season.
Head to Lake Berryessa for warm water
The lake warms up to about 75°F in summer, which makes it the area's best swimming and water-sports spot on hot days.
Ride Yolobus from Davis
Yolobus buses link Davis and Winters, so cyclists and hikers can skip the drive.
Winters through the seasons
- Spring (March–May)
- Green hills and mild days make this the best hiking season around Winters, with native plants blooming along the Cold Canyon trails.
- Summer (June–August)
- Summer afternoons are hot. Hike at first light, then head for creek shade or Lake Berryessa, where the water reaches about 75°F.
- Fall (September–October)
- September stays hot and October turns warm and clear. Fall is also peak fire weather, and smoke can drift in from fires across the region.
- Winter (November–February)
- Most of the year's rain falls in winter, and Putah Creek runs higher. Calm mornings can be foggy.
Activities and the weather that matters
- Hiking Stebbins Cold Canyon: The trail is demanding and suits moderate and advanced hikers. It is best from late fall through spring, since summer midday heat is dangerous.
- Swimming and fishing on Putah Creek: The creek is made for hot summer afternoons, when the shaded access sites along Highway 128 are the coolest place around.
- Cycling the backroads: The farm roads around Winters pass orchards and fields. In summer, finish before late morning. In winter, fog can hide riders on the shoulders.
- Boating and paddling on Lake Berryessa: Warm summer water suits swimming, kayaking, and paddleboarding. Calm mornings are smoothest before afternoon wind picks up on the lake.
