Isola is one of the most popular Slovenian resorts on the Adriatic coast, an excellent beach holiday location. Therefore, go here is best in the summer season. Optimal time for marine bathing lovers are July and August - during this period the water in the Adriatic Sea is the warmer, well done. The minuses of this period are a large number of people on the beaches, as well as the unreasonably high cost of living in hotels and boarding houses.
The same who is more interested in receiving solar baths, the end of May, June and the first half of September are perfect. The sea at this time is already cool enough. The advantages of this time are a small number of people on the beaches, the lower cost of living and vouchers, and most importantly, the possibility with comfort, without a scorching heat to inspect the isola itself, as well as its surroundings. And there is something here: this is the Primorsky town of Piran with a rich history and architectural monuments, and Slovenian Las Vegas Portoroz, and Beauty Venice, where you can get from the neighboring port of the city's city called Coper connected to it ferry message.
Late autumn and winter are not the best time to visit Isola. I am no provincial, not rich in entertainment city, "living" only during the tourist season will completely empty, becomes boring and not interesting. The weather at this time is cool, with the Adriatic blows cold wind, frequent and cold rains.
