Spots covered
MID-GATE
Strongest
Benchmark. NW acceleration zone. Where low-20s happen when Crissy is in the mid-teens.
CRISSY FIELD
Expert only
WSW flow, eddy curl. Best entry slack going into ebb. Current changes inside first.
TREASURE ISLAND
Peak mid-Bay
Peak conditions when the Bay is fully filled in.
BERKELEY
East shore
Fills in later, stays up later in summer. Go-to when the Peninsula is fogged in.
