Read on for my expert tips to help you stay cool when hiking in hot weather. I’ve also included must-have hot weather hiking clothes for summer. 

How Do I Stay Cool on Summer Hikes?

Staying cool while hiking in the summer requires a multi-faceted approach. There will be some days when it’s simply too hot to hike, and that’s okay.

The first way to stay cool on a summer hike is to start as early in the morning as possible. Maybe even look for trails that are good as sunrise hikes. 


This helps you avoid hiking during the hottest part of the day. The earlier you go, the more likely you will be to miss the crowds, too. 

Even when hiking early in the morning, it’s essential to stay hydrated. You sweat more when properly hydrated. The purpose of sweat is to cool you down.

Choose a forested trail to keep you out of direct sunlight in the hot summer months. Shade can makes a huge difference.

Another way to keep cool is by using a cooling towel on your face and neck. You can also bring along a water misting fan to keep you cool.

Take plenty of breaks and don’t hike too quickly. Eat small salty snacks along the way, too. It’s critical that you replace the salt you lose through sweat.

What Should I Wear Hiking in Summer?

Hiking clothes for hot weather can range from tanks and shorts to full coverage outfits that protect against ticks, UV rays, thorns, branches and biting insects. 

What you choose will depend on your own comfort level. Some people prefer full coverage, but others can’t stand it on hot weather hikes.

The most important thing when selecting an outfit for hiking in hot weather is what kind of fabrics you choose. You should never wear cotton or denim.

Choose synthetic fabrics that are both breathable and moisture wicking to help keep you cool, dry, and allow a breeze to flow through.

Light colors are better than dark colors for two reasons. First, they reflect the sun’s rays. Second, you can see ticks more easily. Light colors are a win-win.

Your clothes should fit loosely, but not be so loose that they catch on flora. Loose clothes allow more air to flow through and sweat to evaporate.

Clothing weight is also important. Opt for fabrics that are thin and lightweight to allow for better ventilation and overall comfort.

Finally, a sunhat and sunglasses are always wise choices. A sunhat with a wide brim will keep you cool and provide sun protection, as will sunglasses.

Should I Wear Pants on Summer Hikes?

Pants or hiking leggings do have benefits for hot weather hiking, but not everyone wants to be fully covered in the heat. 

So, the answer to this question is really: it depends. Shorts and hiking skirts are both great for hiking in the summer to help you stay cool.

However, pants or leggings protect you from UV rays, bumps and scrapes, and they also protect you from ticks and other biting bugs.

If you decide to wear pants or leggings, choose a light colored and breathable material. Zip-off pants are great, too.

What Should I Avoid on Hot Hikes?

Hiking in hot weather can go from uncomfortable to dangerous – even deadly – without proper preparation and accommodation.

If it’s mid-summer, avoid full-sun trails entirely. This type of hike won’t be enjoyable and it can easily turn into a dangerous situation.

In addition to avoiding full-sun trails, avoid strenuous hikes or hikes at high elevation. Your body will already be working hard enough to cool you down.

When you add strenuous physical activity to the mix of hot weather hiking, you risk heat stroke or other heat-related injury or illness.

Bring enough water to drink 1 liter (4 cups) per hour of hiking. Normal conditions call for ½ liter, but in hot weather you need more.

Water Bottles - Hiking Hydration

Ideally, you should carry more water than you think you’ll need. But since water is heavy, a water purifying system works if there’s water on the trail.

Lastly, avoid over-hydrating without taking in electrolytes and salty snacks. A sodium deficiency is dangerous, and you lose a lot of it through sweating.

What Exactly Should I Wear in Summer?

Whether you opt for a full-coverage outfit like long sleeves and pants, or a shorts and tank top hiking outfit, materials are of utmost importance.

I’ve compiled top-rated summer hiking clothes, including selections made from natural fabrics and synthetic materials, to help keep you cool on the trails.

These lightweight pants have drawstrings at the ankles to protect against ticks. They also have a drawstring waist for a custom fit.

These pants have four zippered pockets for carrying essentials. They come in 11 colors, though we suggest light colors for summer hiking for ticks and heat.

The material is a breathable, made of a stretchy polyester fabric and spandex blend. Articulated knees allow for easy movement on the trails.

Are shorts more your thing? If so, these hiking shorts are perfect. They’re mid-length, lightweight, and moisture wicking.

They’re stretchy to allow for total range of movement, and they’re breathable and quick drying to cool you down.

Lastly, these shorts have a zippered pocket to keep all your essential items safe while hiking. They also have regular open hand pockets, too.

Wrap-Up Notes

You need the right clothes, the right trail, the right conditions, and the right time of day, to stay cool, hydrated, and safe.

Early morning hikes are better than late afternoon hikes because you’ll stay cooler and won’t risk running out of daylight.

The right fabrics, fit, and style are also important when it comes to what to wear hiking in hot weather. 

Look for easy to moderate trails that are partially or fully shaded the entire route. Full sun or strenuous hikes are a bad idea in very hot weather.

Finally: hydration. Remember to drink plenty of water (1 liter/hr) and bring along electrolyte drink packs and salty snacks to replace lost sodium.
