I visit the beaches in Southern Portugal several times a year, and I always struggle to compare local beaches.
There are plenty of apps that will tell you everything about a beach. Tide charts, wind speed, wave height, UV index. Useful if you know the beaches. Not so useful if you're a visitor trying to figure out which one's right for you.
The best resource I've found is algarvetips.com. Good descriptions, written by people who know the beaches well. But it was a lot of reading, and it left me a little overwhelmed.
