Nestled in the grassy hills of the western San Joaquin Valley near historic Pacheco Pass, San Luis Reservoir State Recreation Area is noted for boating, board sailing, camping, and picnicking. But it’s anglers who find the unit’s three lakes most inviting. The area around San Luis Reservoir and O'Neill Forebay is often very windy, and winds can come up quite suddenly. Watch the wind warning lights at the Basalt entrance station, Quien Sabe Point, and Romero Visitor Center. On the forebay, wind warning lights are located at the Medeiros boat ramp and above the South Beach picnic area at San Luis Creek. Climate/recommended clothing: Summer temperatures here average in the mid-90s and occasionally exceed 100° but evenings are usually cool and pleasant. Rainfall averages eight to nine inches a year, mostly between November and April. In winter, temperatures seldom go below freezing, and tule fogs are frequent. In the spring, the golden-brown hills are coated with a fleeting green, highlighted by bursts of wildflowers colors.
