Every time you’re planning your vacation, you start looking for the temperature at which the sea is comfortable to swim. And whether the sea is warm at this time, where you are going. I decided to write a guide for me and you, where to go to get warm sea and lay on the beach 😎.

Comfortable water temperature for swimming

According to doctors, you can swim in the sea already at +18 +20 degrees with an air temperature of +20 +25 degrees. It’s easy to imagine these conditions – it’s the Black Sea in June, if you’ve been in our south at this time. It is cool to go into such water, but you dip, get used to it and swim.

Well and sea water +25 +28 ° C – it is pure pleasure. What can you compare it with? The Maldives, where the water is +27 degrees and higher all year round. You go into the sea without fear, immediately into a pleasant warm water, like steaming milk.

I want to say that this water temperature is ideal, but doctors warn that the warm more active reproduction of bacteria. Yes, sometimes at popular resorts in the peak season there are outbreaks of rotavirus infections. Watch out for water in your mouth, take a shower after bathing and try to find more secluded beaches 😋

Is it safe to swim in +17 +18 +19 degree water?

Oh, those cheap off-season tours – to the same Turkey and Cyprus in late fall, winter and spring. We were tempted to fly too. Last time to Kemer in December. The water was +18 +19 ° C, and the air was heated to +24 ° C during the day. I never dared to swim, although we were lounging on the beach in T-shirts during the day. But the German pensioners were swimming and sunbathing, and they looked happy.

To my senses, such water is very refreshing and invigorating. Swims of course should be short, before swimming it is better to do a little warm-up and warm up. Be guided by how you feel and your state of health. Pregnant women and people with cardiovascular disease should beware. By the way, during the off-season you can make your holidays more pleasant by using heated swimming pools, open, with wonderful views, some even with sea water.

What is the optimal sea water temperature for children?

Children are ready to swim in any and up to blue lips. But as a mom, I focus on making the water comfortable for myself – from +22 ° C. In water +22 +23 +24 °C allow a swim for 10-15 minutes, and then call to warm up in the sun. If the sea is warmer, you can splash for half an hour. I remind you that it is important not to lose vigilance while your child is in the water and always stay in sight. Do not forget to wear a panama and cover your shoulders (a T-shirt will help).

With infants under a year should be more careful. It will be enough to dip them or let them splash their legs in warm water of +24 °C. Make sure that sea water does not get into the mouth. Take for your baby a small inflatable pool for the beach.

Where best to go to the sea – a choice of resorts by month

Deciding where best to go on your planned vacation to rest 100% to the most season and the sea is warm? I have analyzed and compiled information on water temperatures for all countries and resorts and compiled handy tables. So your bathing season can last all year round!

Summer – June, July, August

The so-called high season for the Black Sea and Mediterranean Sea. That said, the Black Sea is always cooler.

From recent trips: Rhodes in early June. The heat is +30 °C and above, but the water seemed like it was cool when you went in. But in just a minute you didn’t want to go ashore anymore.

In Southeast Asia the best season is in Bali in Indonesia, Nha Trang in Vietnam and Samui in Thailand, in the Indian Ocean is good in the Seychelles.

At the other resorts in Southeast Asia and in the Caribbean region the so-called rainy season begins. It is possible to have a rest, to bathe in the sea too, but there are nuances – heat and high humidity, periodic showers, waves in the sea, cloudiness.

In the Dominican Republic and Mexico, though the season is humid, but the water in the sea is gorgeous, steamy milk. At the same time the rains are short, and often even at night. So you can fly!)

Fall – September, October, November

A time when you can enjoy the velvet season in the Mediterranean and Black Sea at the beginning of the season. The water in September and October is incredibly pleasant to swim in, warmed up to maximum values.

From recent trips: Crete in early October seemed wonderful. Not so many tourists, discounts on accommodation and car rent, but what a warm sea. Really tender. The weather was pleasant with comfortable +28, and in taverns there were treats straight from the branch 😋 October in Sochi is a little different – in coats, but in the sun, and in hands ripe pears, figs and persimmons.

Autumn is good in the Near and Middle East, because the intense heat subsides. And in the middle of the fall tourist season starts in Asia – everyone rushes to Thailand, Vietnam and India. Plus November is one of the perfect months to travel to the Caribbean.

Recent trips: the Maldives in mid-October. Just a little before the official season in November. No rain, air +30, water +28. The only “but” – waves in the ocean, noticeable and scary only during the transfer to the islands. Our speedboat was thrown to the waves with incredible strength. On the islands themselves no more waves thanks to the reefs.

Seas and their beach seasons

We decided to separate out our favorite seas for swimming and indicate the most comfortable season on their coast.

Black sea – for swimming from June to September, maximum warmth in August to +26 +27 degrees. In September a pleasant velvet season, when the beaches are a little freer. At the same time the water is warm to +25 ° C.

The Baltic Sea is cooler than the Black Sea. To swim accurately, it is better to plan a vacation from late July to mid-August and choose places with shallow water, they warm up faster. But the water is not particularly warm even in August, to a maximum of +23 ° C.

The Mediterranean Sea is the bathing season from May to October, the warmest time from July to September with a water temperature of +28 +29 degrees (the coast of Turkey, Cyprus, Israel and Tunisia). The Mediterranean coast of Greece, Italy and Spain is a little cooler, in July and August at about +25 +27 ° C.

The Aegean Sea is very beautiful coast of Turkey and Greece. The season for swimming in the sea lasts from June to October. In July and August, the water is warmest – up to +26 degrees. Each year, tour operators begin charter programs from May and lure everyone with cheap tours. But the water in the Aegean Sea in May is cool +19+20 °C.

The Red Sea is warm all year round, the water temperature does not drop below +20 degrees, even in winter. It is believed that the best time for swimming is from March to May, when the water is warm to +26, but without the unbearable summer heat. Although those who love Egypt, ready to relax on the Red Sea at any time of year.

The Dead Sea – the main tourist season with the most comfortable temperature of air and water is observed in autumn in October and November and in spring from April to May, when the water is pleasant +26 +30 ° C. In summer, however, it is unbearably hot, and in winter the desert is cool and there are strong temperature variations during the day.

The Caribbean Sea is warm all year long. The main tourist season in the Caribbean is from November to April (water +27 degrees) with a slight drop in temperature in January and February (water +26 ° C).
