The Best Rainy Day Activities for Kids in the UK

The UK gets on average 133 days of rain per year. Parents who wait for good weather before going out are spending four months a year waiting. This guide covers the activities that actually work in wet weather — indoors and out — so a rainy day becomes an opportunity rather than an obstacle.

The outdoor rainy day case

Before we get to indoor activities, let us address the outdoor option. Children who grow up being taken outside in the rain develop a fundamentally different relationship with bad weather than those who only go out in the sun. Rain is not a reason to stay inside — it is a different kind of day, with puddles, worms, the smell of wet earth, and the satisfaction of being out when everyone else is not.

The equipment makes the difference: proper waterproof trousers and jacket for children (not a cagoule that lets everything in), wellies with a good depth, and a change of clothes in the car. With that kit, a rainy day walk is as enjoyable as a sunny one, and considerably more memorable.

Outdoor rainy day activities

Puddle walk

A formal puddle walk — with the explicit goal of jumping in as many puddles as possible, rating them by depth and splash quality — is among the most universally loved children's activities in the British tradition. Requires wellies, waterproofs, and a parent willing to get wet.

Woodland walk in the rain

Woodland is different in the rain. The smell of petrichor, the sound of rain on leaves, the earthworms on the path, the way the colours deepen. Pick a local woodland and walk it in the rain deliberately. Bring a hot drink in a flask for the walk back.

Puddle art

Take chalk to a puddle and draw around the edge immediately after rain. Return in an hour and observe what has changed. A surprisingly absorbing activity for children aged three and up.

Beach in the rain

A beach in the rain, with the right kit, is a genuinely exciting experience for children. The sea looks different, the sand is firmer, and there is almost no one else there. Fossil hunting, rockpooling, and beachcombing are all better in quiet, wet conditions.

Free indoor activities

Free museums

The UK's free museum network is exceptional. In London: the Natural History Museum, Science Museum, Victoria & Albert Museum, British Museum, Tate Modern, National Gallery, and more — all free. Outside London: most major cities have free municipal museums, many with strong children's programming. Check in advance for free family events during school holidays.

Free libraries

Libraries remain one of the most underused free resources for families. Most have children's sections with picture books, reading programmes, and often activity sessions. Getting a library card is free. Spending a rainy morning letting children choose their own books, and reading together, requires no preparation and costs nothing.

Indoor den building

Blankets over chairs and sofas, cushions for walls, a torch inside. Children will spend an hour building and the rest of the afternoon inhabiting. No materials required beyond what is already in the house.

Kitchen science

Bicarbonate of soda and vinegar volcanoes. Oil and water in a jar. Skittles and warm water (the dye dissolves in a radial pattern). Celery in coloured water to demonstrate how plants drink. Most kitchen science activities require only basic pantry ingredients and produce reliably astonished children.

Craft activities for rainy days

A well-stocked craft box — coloured paper, scissors, glue, paint, stickers, old magazines — can sustain a rainy afternoon without any planning required. The most successful rainy day craft activities tend to have a destination: something that will be displayed, given as a gift, or used.

• Making birthday cards for upcoming birthdays
• Creating a family newspaper (write the stories, draw the pictures, glue it together)
• Building a cardboard box city, house, or vehicle
• Making puppets and performing a show
• Creating a scrapbook or memory collage from old photos and drawings

Cooking together on a rainy day

A rainy day is a good day to cook something that takes longer than usual — a bread that needs to rise, a soup that simmers for hours, a batch of biscuits. Children who cook develop practical skills and a sense of achievement. The mess is worth it. The biscuits are also worth it.

Making rainy day memories

The rainy day adventures that children remember are the ones that were treated as adventures rather than compromises. The woodland walk that ended with hot chocolate. The afternoon in the museum followed by chips on the way home. The den that was so good it stayed up for a week.

Log them in PocketTreasures the same way you would log a sunny day adventure. The voice note that captures "we were the only people at the beach and Jake said it was like our private beach" is a memory worth keeping, rain and all.
