San Luis Reservoir, California (USA)

Winds are generated by a similar weather pattern to Sherman Island. If the coast is fogged in (light winds from the south at Pigeon or Waddell) and the central valley is hot, then the Reservoir will be cooking. Light wind days will be in the 8-15 knot range. High wind days 15-30 knots. Once or twice a month, the weather will really set up, and you will get some very windy conditions (40+ mph). Most good blows cover 3 or 4 days, then the weather pattern needs to set itself up again. When the pattern is on, it tends to be windy in the a.m., then drops off mid-day. Winds ramps up starting early afternoon. Sometimes dies a bit, then rips right before dark. Really windy days will blow steady all day. The Res. can really surprise you at times. Be prepared to get blown of the water once in a while. Wind on the upper reservoir will generally be a bit stronger, and more southerly.

Even in the summer, the very windy days tend to be cool. If the coastal fog is in, it can be very cool to cold in the a.m. and a full suit may be needed for dawn patrol sessions, even in the heat of summer. Lighter wind days can be quite warm/hot. Those more resistant to the cold might just go with a rashguard. For most, a shorty is recommended even on warm days.

Storage reservoir for the California Aqueduct. No kiting in the O'Neill Forebay (power lines). Kiting allowed on the upper reservoir. Windsurfing allowed on both Forebay and upper reservoir. Water comes from the aqueduct, and is about 60-75°F, and pretty clean once you get away from shore, where it can be muddy. Watch out for the clam shells and rocks, very sharp.
