High season in Formentera is July and August. During these 2 months, prices shoot up to the higher level, the Island gets full of tourists, traffic gets horrible and the beaches are so crowded that you can hardly lie on the sand or see the horizon due to the large number of boats and yachts moored in its wonderful waters.
If your holiday schedule will not allow to come in another period, relax and try to make the most of your time in Formentera.
But if you can choose, best time to come to Formentera is without doubt May, June, September and even October. Prices offer good value for money, all accommodation, restaurants and shops are open and beaches are like heaven in paradise.
No multitudes, no traffic and excellent service in every sense.
