Summer Activity Ideas for Under 5s: Keeping Cool in the Sunshine

When the sun is shining, summer can feel like pure magic for little ones. But for under 5s, hot weather also means thinking carefully about how we play, stay safe, and keep cool while still enjoying all the excitement of the season.

The good news? You don’t need complicated set-ups or expensive resources. Some of the best summer learning moments come from simple, sensory-rich experiences that help children explore the world around them.

Here are some easy, engaging summer activity ideas for under 5s!

Water Play Wonders

Water play is a summer staple for a reason. It naturally cools children down while offering endless opportunities for exploration.

Try:

• Filling tubs with water and cups, spoons, and funnels

• Adding plastic animals or toys for imaginative play

• Creating a “car wash” for toy vehicles

• Pouring and scooping stations with different containers

Developmental benefits: encourages hand-eye coordination, early maths concepts (full/empty, more/less), problem-solving, and sensory exploration.

Ice Play Exploration

Ice is a brilliant way to cool down sensory play.

Try:

• Freezing small toys in ice cubes for children to “rescue”

• Ice painting using coloured ice cubes (freeze washable paint mixed with water) on paper

• Ice sensory bins with spoons and bowls

• Watching ice melt outdoors and talking about changes

Developmental benefits: supports curiosity, scientific thinking (cause and effect), language development, and fine motor skills.

Shade-Based Outdoor Adventures

You don’t need to avoid the outdoors—just shift how and where you play.

Try:

• Picnics under trees or shaded areas

• Storytime outside on blankets in the shade

• Chalk drawing on cool surfaces

• Nature treasure hunts (leaves, sticks, flowers) – click here to find printable treasure hunts.

Developmental benefits: builds connection with nature, supports communication and storytelling, and encourages physical movement in a safe environment.

Cool Creative Play

Art doesn’t have to stop in summer—in fact, it can become even more exciting outdoors.

Try:

• Water painting on fences, patios, or paving stones using washable paints or simply water.

• Large-scale mural painting with brushes and water

• Sponge stamping with cool water trays

• Nature collage using leaves and petals collected outside

Developmental benefits: supports creativity, sensory development, and early writing skills through mark-making.

Frozen Snack Fun

Snack time can also become part of the play experience.

Try:

• Frozen fruit like grapes, berries, or banana slices

• Homemade ice lollies with fruit juice or yoghurt

• “Ice excavation” using frozen fruit cubes in water play

• Picnic-style snack breaks in the shade

Developmental benefits: encourages independence, healthy eating habits, and sensory exploration through taste and texture.

Gentle Indoor Alternatives (for very hot days)

Sometimes the best option is a cool indoor space with calm, low-energy activities.

Try:

• Sensory trays with rice or pasta

• Soft play setups with cushions and tunnels

• Story corners with books about summer and nature

• Music and movement with gentle dancing

Developmental benefits: supports emotional regulation, language development, and imaginative play.

Staying Safe in the Sun

While summer brings plenty of opportunities for outdoor adventures, it’s important to remember that young children are more sensitive to the sun’s rays. A few simple steps can help keep little ones safe and comfortable while they enjoy the warmer weather.

Remember to:

• Apply child-friendly sun cream regularly, especially after water play or if children have been sweating,

• Encourage children to wear sun hats when playing outdoors,

• Choose shaded areas for outdoor activities where possible,

• Keep little ones hydrated with plenty of water throughout the day,

• Plan busier outdoor activities for cooler parts of the day when the sun is less intense.

Simple moments often become the most memorable ones—splashing water, melting ice, barefoot grass adventures, and laughter in the shade.
