Tel Aviv, as you know, is right by the Mediterranean, so if you end up here around summer (which could very well start as early as April or May and go on until October, some years), you’re probably going to want to spend some time at the beach.
The rule is simple: the farther away from the centre you get, the less crowded it is. Up north, you have Tel Baruch (תל ברוך) and HaTzuk (חוף הצוק) beaches, which are usually great for families. Further down, Bograshov (בוגרשוב) and Frishman (פרישמן) beaches – right where these two streets end, respectively – will probably be quite crowded, but vibrant and full of character.
And closer to Jaffa, the area of Alma beach (חוף עלמה) is really nice, right across from Charles Clore Garden and beautiful Neve Tzedek (נווה צדק), and with a great view of the old city of Jaffa.
I would like to recommend the Hilton beach (in front of Hilton hotel )
It is Tel Aviv gay beach and it friendly to everyone, sometimes it less crowded than the other beaches of the city.
