Ynet recently reported that October 2013 was an all time high when it comes to tourism to Israel. While Tel Aviv specifically was not mentioned in this report, we do believe a lot of people who come to Israel visit Tel Aviv as well. Especially if they come due to the warm weather, like the article mentions!
So far Israel has had over 3 million tourists come over during 2013, and 339 000 during October 2013 alone! So if you're thinking of coming over, you are definitely not alone!
