I grew up just across highway one from the harbor and have visited here many times. I still live close enough to make frequent trips to Half Moon Bay and count myself fortunate to be able to do so.
In the summer, the coast is frequently fogged in in the afternoon which puts a damper on photography. Occasionally, however, the fog stands off in a most agreeable fashion and we get treated to a wonderfully warm, sunny late afternoon.
No really, keep out.
