At this oceanside concert you don’t have worry about sand, wind or riptides. This venerable jazz venue on Miramar Beach at Half Moon Bay is perched along the Pacific with serene views and warm acoustics. It is basically a light-filled beach house, spectacular even when the coast is fogged in. Performances take place every Sunday, with two sets starting at 4:30. Doors open at 3. The talent is high level and mostly cool jazz, with a smattering of blues, rock and folk. Food is available at intermission and there are a limited number of picnic tables.
