Dawgpilot is correct. FAA Facility Maps, AirMap and SkyVector all agree. You're in G airspace with Class E5 well above that so you're good to 400' and yield to manned aircraft.
Be cautious since there are several airports nearby so I'm sure you may see lots of activity in the area. In my experience coastal beach areas may have low flying aircraft, para-sails and god knows what else flying low and slow for sightseeing or recreation. Keep your head on a swivel and if you have someone with you have them keep an eye on the sky.
