Best Time to Visit Mykonos: High Season in Mykonos [July to August]
When you try to book a room in Mykonos, you will find out that officially the high season starts at the beginning of July and might be considered until the 15th of September. The high season is considered by many the absolute best time to visit Mykonos.
The peak of the high season in Mykonos is from the 20th of July until the 20th of August. These 30 days is the peak of the traffic on the island, as the weather is above 30 to 35 degrees, the Greeks are on vacation and visit the island and everyone is of course on vacation during August.
Prices of Hotels during the High Season
During the high season there is almost no accommodation on the island below 100 to 120 euros per night for a double room. And this goes for even the simplest rooms on the island. For a 3 star hotel you should expect to pay around 150 euros/night, for a 4-star hotel around 250 euros/night and 5 star hotels are anywhere above 250 euros/night.
Sea Temperature during the High Season
The warmest sea in Mykonos is in August and the first days of September. The early July (1st to 15th of July) varies. Some years it is really warm, like August and some other years it might be a little bit chilly. If for example late June has 4-5 days of +30 degrees temperature, which happens every now and then, the sea during the first weeks of July will be warm. More or less, during July, August and the first two weeks of September you will enjoy swimming.
Partying during the High Season
Partying in Mykonos is at its best during July, August and the first couple of weeks in September. The absolute best period for partying is the 1st of August until the 20th of August. These three weeks, are full of famous DJs visiting the island, and all the great parties take place at that period, as it is the absolute peak of the high season and Mykonos is the place to be for the rich and famous.
Crowds during the High Season
From the 1st to the 20th of August, you will find the most crowds on the island, compared to all the year. There will be traffic on the roads, parking is difficult, and the beaches are full with people. 20th of August until 15th of September and 1st of July until 1st of August, there are about 20 to 30% less people on the island.
Chance of bad weather during the High Season
Temperature: August is the warmest month, with 25 to 30 degrees celcius temperatures on average. July is usually a couple of degrees less warm, i.e. 24 to 28 degrees celcius and early September is 21 to 26 degrees celcius on average.
Rain: The chance of rain during the high season is low. There are usually one or two rainy days during July and August and usually it is a quick rain that lasts for a couple of hours and then the sun goes out and everything gets back to normal. You should not worry about having your vacation ruined by rain during the high season. September has usually around three to four raining days.
Winds: This is a factor that you most probably don’t expect to take under consideration, however for Mykonos island it is an important one. Mykonos is called “the island of winds” in Greece, as it is exposed to strong winds that are called “meltemia” in Greece. These winds are usually during August, and they last for some days. They blow from the north, that’s why almost all the sandy beaches are on the south.
Suntime: July has the most hours of sunshine per day, with around 14 hours of daytime. August and June are at 13 hours and May and September even below that.
Shoulder Season in Mykonos (May, June and September, October)
The shoulder season is considered by some visitors the best time to visit Mykonos. During the shoulder season in Mykonos, prices are lower (with the exception of the first days of September), crowds are less, the weather is not as hot as in July and August and the parties on the island are less. Still, it is a good time to visit Mykonos.
Prices of Hotels during the Shoulder Season
The prices of the hotels in the shoulder season are significantly lower during the shoulder season. For example, check the price of the Ilio Maris hotel on the 5th of June, compared to the 5th of July. In June the price for a room in this hotel is 168 euros per night and in July it is 268 euros. Meaning that the same room is 60% more expensive in July, compared to June. Due to the lower hotel prices, combined with a lot of sunshine and decent crowds, the shoulder season is considered by a few visitors, the best time to visit Mykonos.
Sea Temperature during the Shoulder Season
September has the warmest sea temperatures in the shoulder season. You will enjoy swimming during September, as the sea is still warm from the high temperatures of August. In June the sea is colder than in September and in some years, it is too cold if you want to stay a long time inside the sea.
Partying during the Shoulder Season
Partying is not at its best during June and September. There are some sporadic appearances of famous djs but don’t expect the crazy party atmosphere of July and August. Bars in the island are still busy but not packed with people.
Crowds during the Shoulder Season
There are at least 30 to 40% less people on the island during June and September, compared to July and August. So, expect to find less people on the beaches, in the bars, clubs and restaurants. This might be a good or bad thing depending on your preferences.
Chance of Bad Weather during the Shoulder Season
Temperature: June is two degrees less than July and August. The average temperature in Mykonos in June is 21 to 27 degrees celcius. September is almost the same, with 21 to 26 degrees average temperature.
Rain: May to September is the period with the less rainy days in Mykonos throughout the year. Mykonos has 31 rainy days in a total of 365 days per year and these rainy days are mostly concentrated around December to February. May and September might have a couple of rainy days.
Winds: Mykonos is generally windy but the strongest winds are usually during August. May and September will have winds blowing with at least 4-5 days of very strong winds.
Sunshine: June has 14 hours of sunshine and September around 13 hours of sunshine, so they are both excellent months to enjoy your time on the beach.
Low Season in Mykonos (April,May, October, November)
The low season is not the best time to visit Mykonos. During the low season in Mykonos, the prices are the cheapest you can get, the crowds are less than in June to September and the sea is usually too cold to swim. Partying in Mykonos is very very limited, with the exception of some weekends in April and May, when many university schools are organizing trips to Mykonos due to the low prices, and there is a more upbeat atmosphere on the island.
Prices of Hotels during the Low Season
The same hotel we used in the example above, Ilio Maris, costs 118 euros per night on 5th of April. We remind that it costs 168 euros on the 5th of June and 268 euros on the 5th of July. So, in low season, the prices are usually 60% cheaper than during the peak high season in Mykonos.
Sea Temperature during the low season
April is always too cold to swim. In May, you have to get lucky and if there is a week of very high temperatures, the sea will get at a temperature that you will be able to withstand some minutes in the sea. But usually, May is also not a good month for swimming. You have more chances to get a nice sea temperature for swimming in October, as September tends to be hot in the last years and sometimes the sea keeps its warm temperatures up to the first days of October. November is always a no-go for swimming.
Partying during the low season
There are no parties in the low season in Mykonos. Bars are open but there are very few people there. Don’t go to Mykonos during the low season if you want to party on the island.
Crowds during the low season
During the low season, crowds are at least 80% less on the island, than in July and August. Not all shops are open in Mykonos and although you will not feel like you are on a “deserted island”, the “Mykonos experience” is not what you will get from June to September. Having said that, towards the end of May, the situation gets better. Have a look below on the crowds at Little Venice on 25th of May:
When is NOT the best time to visit Mykonos
We find no reason for anyone to visit Mykonos in December, January and February. Most shops are closed, there are only locals on the island, you will not be able to swim, there is limited hours of sunshine and you will not enjoy your stay at Mykonos.
