Mrs. 44 and I walked Palm Beach this morning from Radisson to Marriott. The beaches looked generally good. There are some spots with a thin lawyer of seaweed sloshing about and others with fine shells. However, nothing prevented a fine stroll or a relaxing morning reading and lounging. Plenty of people were under the bright sun, passing clouds, and blue sky. Thawing their bones is what I think most were doing.
In some places you can see where the sand has been eroded away to the palm trees. Other locales have a drop off to the water. Also, you'll note about 10-20 feet into the water there is a secondary drop, usually where the small waves are breaking. You'll want to take extra care swimming in those spots.
I broke out the little Sony camera with the panorama function and snapped a few shots. They can be seen at:
