How to Deal With the Sun in Greece This Summer

How to Stay Cool and Enjoy the Sun in Greece This Summer

Summer in Greece looks dreamy on Instagram, but the reality of the heat catches thousands of travellers off guard every year.

During July and August, temperatures regularly climb above 35°C (95°F), while UV levels in popular islands like Santorini, Mykonos and Crete often hit “very high” or “extreme” risk levels by midday.

What makes the Greek heat feel so intense is the combination of:

• Strong Mediterranean sunshine for 12+ hours a day;
• Dry heat that dehydrates you faster than expected;
• White buildings and stone streets reflecting sunlight back at you;
• Long walking days, beach trips and ferry travel with little shade;
• High UV exposure even when temperatures feel manageable;

Many first-time visitors underestimate how quickly the sun can drain their energy.

A few hours outdoors without enough water, shade or sunscreen can lead to:

• Severe sunburn;
• Dehydration;
• Heat exhaustion;
• Headaches and dizziness;
• Completely ruined sightseeing plans.

Locals already know the secret: in Greece, you do not fight the sun, you plan around it.

The difference between an unforgettable summer holiday and a miserable one often comes down to knowing how to stay cool in Greece during summer before stepping outside each morning.

This is especially important when visiting a hot country where the sun can feel far more intense than many travellers expect.

Do Not Try to Be Outside All Day

One of the biggest mistakes travellers make in Greece is trying to sightsee nonstop from early morning until sunset.

It may sound doable while planning the trip, but Greece’s summer heat can become surprisingly draining after only a few hours outdoors.

If you truly want to understand how to stay cool in Greece during summer, the secret is not doing more, it is timing your day smarter like the locals do.

During July and August, the hottest hours are usually between late morning and late afternoon. In many Greek towns and islands, life naturally slows down during this period because the heat becomes too intense for constant activity.

Visitors who ignore this often end up dealing with:

• Dehydration and headaches
• Sunburn after long walking hours
• Heat exhaustion and dizziness
• Low energy by evening
• Ruined sightseeing plans halfway through the trip

Instead of pushing through the heat, locals structure their days around cooler hours.

That usually means:

• Exploring towns and archaeological sites early in the morning
• Taking beach trips before midday
• Resting indoors or finding shade during peak afternoon heat
• Saving restaurants, shopping and long evening walks for after sunset

Wear Clothes That Actually Help in the Heat

Packing for Greece is not really about dressing up all the time — it is about understanding how to stay cool in Greece during summer once temperatures start climbing during the day.

Comfort matters far more than fashion when the heat becomes intense.

Light and breathable clothing usually makes the biggest difference.

Loose fabrics feel far easier to wear while walking around islands, ports and historical areas, especially when there is very little shade nearby.

Shoes matter more than many people expect as well.

Streets in Greece are often uneven, steep or covered in stone that becomes extremely hot in direct sunlight.

Comfortable footwear can make long walks through villages and coastal towns much easier.

A hat is also worth bringing, particularly for anyone planning boat trips or long afternoons by the beach.

The sun can feel relentless during the middle of the day, and having some protection makes being outdoors much more manageable.

Bring Proper Sunglasses and Check Your Eyes Before Travelling

People often focus on protecting their skin during summer holidays while forgetting how much strain strong sunlight can place on the eyes.

In Greece, reflections from the sea, white buildings and pavements can make the brightness feel even stronger throughout the day.

A good pair of sunglasses is genuinely essential rather than something optional.

Proper UV protection helps reduce discomfort, glare and headaches, especially during long periods outdoors.

Cheap sunglasses may look fine, but they rarely offer the same level of protection or comfort.

Polarised lenses are particularly useful around the islands because they cut down reflections from the water and make bright conditions easier to handle.

Before travelling, it can also be worth booking an appointment with an expert eye specialist, especially if you wear glasses or contact lenses regularly.

Having the correct prescription before the trip can make daily activities far more comfortable, particularly when driving or reading signs in bright sunlight.

Anyone who wears contact lenses should also think about bringing spare pairs and eye drops. Heat, sea salt and dry air can sometimes irritate the eyes more than expected after long days outside.

Take Breaks at Seaside Bars Instead of Constantly Rushing Around

One of the nicest parts of being in Greece is that people are not constantly in a hurry.

Long lunches, slow coffees and afternoons spent near the water are part of everyday life, particularly during summer.

Trying to move constantly from one activity to the next in extreme heat usually becomes tiring very quickly.

Taking regular breaks at seaside bars like Barbarossa Bar or tavernas can completely change the pace of the day and make the heat easier to deal with.

Many places along the coast have shaded seating areas where you can cool down for a while without leaving the beach atmosphere behind.

Stopping for a cold drink or an extended lunch during the hottest hours often feels far better than forcing yourself to stay active the entire time.

These slower moments also end up becoming some of the most enjoyable parts of the holiday.

Sitting by the sea, escaping the strongest sunshine and watching daily life pass by is part of what makes summer in Greece feel different from anywhere else.
