It’s one of our favorite times of year: summer brings sunshine, freedom, and long days full of possibilities. For children, it is an opportunity to play, explore and connect with nature at a different pace than the school year allows.

Summer in Spain means long, sunny days and lots of time outdoors, whether on the beach, the park or simply on the terrace. While it’s tempting to stay outside all day, especially with kids eager to explore, the heat demands extra care. Young children are more vulnerable to high temperatures because their bodies are still developing and are less efficient at regulating heat.

Of course, spending time indoors is also part of a healthy summer rhythm. If you’re looking for ideas to keep the kids busy at home during the hottest parts of the day, check out our blog atMontessori Inspired Indoor Activities. But when it comes to enjoying the outdoors, especially trips to the beach, here are six essential things to keep in mind to help your child stay safe and comfortable in the summer sun.

1. Hydration

Children need regular hydration throughout the day, even if they don’t feel thirsty. Offer water frequently and avoid sugary drinks like juice or soft drinks, which can contribute to dehydration. A child-friendly water bottle they can carry themselves supports independence and helps them develop awareness of their own needs. For flavor, try infusing water with slices of cucumber or berries. Fresh fruits like watermelon or oranges can also boost hydration and provide a refreshing snack at the beach.

2. Dress for the weather

Light, loose-fitting clothing made from breathable fabrics such as cotton or linen helps regulate body temperature. A wide-brimmed hat and UV-protective sunglasses add extra protection for sensitive skin and eyes. Opt for brightly colored swimsuits when you go to the beach; Neon or high-contrast colors are easier to spot in the water.

3. Avoid peak heat hours

Plan outdoor activities for the cooler parts of the day—early morning or late afternoon. Between 11am and 4pm, the sun’s rays are strongest. If you’re heading to the beach or pool, seek out shaded areas and make use of umbrellas, tents, or natural shade to give children a break from direct sun exposure. Protective beach shoes can also prevent burns from hot sand and surfaces.

4. Watch for signs of overheating

Look for signs such as red skin, rapid breathing, irritability, or unusual tiredness. These may indicate heat exhaustion. Take your child to a cool area, offer him water, and use a damp cloth on his skin to help him cool down.

5. Sunscreen is essential

Choose a broad-spectrum sunscreen with SPF 30 or higher and apply it liberally to all exposed skin at least 20 minutes before going outside. Reapply every two hours or after swimming or sweating. For families who prefer more natural options, look for mineral-based sunscreens with zinc oxide or titanium dioxide. These sit on the surface of the skin rather than being absorbed, offering effective protection without synthetic chemicals. Always check that natural sunscreens are suitable for children and provide UVA/UVB coverage. Don’t forget places that are often overlooked, such as the ears, feet, and the back of the neck, and always check the expiration date. Sunscreen stored in hot places (like beach bags) can degrade faster.

6. Safety in the water

Hitting the beach and pool is a summer highlight for many families, but it comes with its own safety considerations:

• Sparkly swimsuits: Choose swimsuits in neon or bright colors that are easy to spot in the water.
• Water Watchers: Designate a responsible adult to supervise water play at all times, rotating every 15 to 30 minutes to stay alert.
• Shade breaks: Bring a beach tent or umbrella to give little ones a shady place to rest, hydrate, and reapply sunscreen.
• Hot surfaces: Sand and boardwalks can burn; Try before playing barefoot and wear beach shoes to protect little feet.

Being sun smart doesn’t mean missing out. With the right habits and a little preparation, kids can safely enjoy everything the Mediterranean summer has to offer: from sandy feet and salty baths to garden adventures and evening walks.
