Best Times to Visit Mykonos
The best time to visit Mykonos is September and October. Sitting in the Aegean Sea, this island's weather permits a year-round flow of tourists, but in those months you'll see that the crowds have left, the water remains warm and the hotel rates descend back into a reasonable range. The spring, before the summer rush comes, is also a great (and affordable) vacation time. Mykonos experiences a typical Mediterranean winter: mild with temps that dip to the mid 50s. June, July and August are especially busy; temperatures average in the upper 70s and 80s, and there are nonstop parties and pricey hotel rates.
Mykonos sees nonstop action in the summer. Parties rage with the waves, and hotel rates peak with the temperatures. Although this is the warmest time (mid 80s), the ocean breeze and frequent dips in the water cool down visitors. You'll also get to experience several Mykonos festivals honoring the patron saints. Book your accommodations in early spring if you want to pay anything less than premium.
You'll trade diminished crowds and party activity for more personal space on the beaches (still with warm waters) and lower accommodation prices. It's well worth it. Average daily highs stay in the 70s and 80s with clear skies.
In the low tourism season, you'll be greeted with discounted rates and cool weather -- think daytime temps in the 50s and low 60s. These are certainly bearable, but they preclude sunbathing for most travelers.
High 60s and low 70s with a spacious room overlooking the Mediterranean sounds pretty good, especially when you aren't paying an arm and a leg. This short window of warmth before the crowds arrive is a great time to visit.
