Yes, pop-up shades and umbrellas are allowed on the beach at the oceanfront as well as the bay. At the oceanfront, pop-up tents must be no bigger than 10ft x 10ft in size and you must be able to see "through" them from all sides.
On hot, popular days at the oceanfront the beach can get fairly crowded so I would suggest that you be respectful to other beach-goers and find a place that won't interfere with the people around you.
Lastly, if a lifeguard feels that your pop-up shade is interfering with their ability to safely monitor the water for swimmers in distress, you may be asked to remove the pop-up shade or at least move it to a location that does not present a safety hazard or obstruction to the lifeguards.
Another word of advice: Please be sure to anchor your umbrella or pop-up shade securely. The wind at the oceanfront can gust hard at times. The last thing you want to be doing is chasing your umbrella or tent down the beach or ruining someone else's vacation because your shade hit them.
Just be courteous and all is good at the beach!
HAVE A GREAT DAY AT THE BEACH!
