I think an important aspect seems to have been omitted. You really want to sit at the beach and just watch the surf for 10 minutes or so. You can get an idea about the timing of the sets.
You want to enter and exit between the major sets. If you just watch for two or three minutes and decide it looks good and then get dressed and just enter when it is convenient, you can get hammered. It is somewhat more difficult to do when exiting, but sometimes it makes sense to wait for a big set to pass while you sit outside the break zone and rest and then sprint in after the big waves have passed.
I used to do a lot of night diving off the beach. When you really can't see the waves, you want to dial down your acceptable conditions.
It is also reasonable to consider that the seas can build while you are down and of course it may be very important to consider the tide cycle in certain areas, because the beach may look very different when the tide is in or out- especially over a rocky shore. When the tide is in, the area may be passible, with the tide out, you could be faced with a very shallow, rough and rocky bottom with sea urchins to traverse.
As others have said, if you are unsure about your abilities and the conditions, it is better to get in and check it out without scuba gear on. You can scramble over rocks, obstructions and waves a lot easier without a tank on.
Asking for guidance from the locals is always prudent.
Lastly, you want to have zero air in the BC when entering and crawl/swim on the bottom when trying to get from the beach to deeper water.
