Water temps are typically 10 degrees warmer than anywhere northwest.
With 28 miles of sand beach, you never have to worry about crowds.
If you're looking for company in the water, you're most likely to find other surfers at the Seaview beach approach on 38th street Seaview.
If you're already an experienced surfer and are looking to explore the area, look for east winds or under 10 knots, swell height under 4 ft, and swell period 11-15 sec when checking your favorite surf forecast website.
A few things to keep in mind:
The water here can get warm but it is NEVER warm enough to surf without a wetsuit
There is often a side shore current on the beach which is not dangerous in itself but is something to be aware of (hint: don't drift further than you're willing to walk back up the beach)
The surf is usually bigger than it looks from the beach, the slope of the beach is very shallow
If you are not a strong paddler, stay waist to chest deep
