Indoor Activities in Brighton: What to Do When It Rains

LaserZone: a seafront anchor for older children and groups

For a group of teenagers or a rainy afternoon with friends, LaserZone in Brighton is the straightforward pick: a multi-level arena where players wear laser packs and score by tagging opponents and hitting their bases. It sits two minutes from the seafront, which makes it easy to combine with a seafront walk when the rain eases or to reach quickly from the pier end of town. Book nothing on guesswork, though: check session times and whether a slot needs reserving before you build the day around it.

The trade-off is that laser tag suits older children who can handle the equipment and the pace; it is a poor fit for toddlers and a waste of money for anyone who would rather be browsing. If your group is mixed, split the day: the laser players go one way and the rest of you take shelter somewhere calmer. Group sessions tend to fill when rain is forecast, so an early or late slot is usually safer than the middle of the afternoon.

Rainy days with younger children: Monkey Bizness near Lewes

Families with under-eights are better served by an indoor play centre, and Monkey Bizness on the outskirts of Lewes offers giant climbing frames, slides, ball pits and a café. Note the geography: this is Lewes, not central Brighton, so it works as a half-day trip rather than a quick dash between showers. The café matters more than it sounds, because it gives adults somewhere to sit while children burn off energy.

Play centres get loud and busy at weekends and in school holidays, so a weekday morning is the calmer choice if your dates allow. Check session lengths and whether you need to book a slot before travelling, since capacity rules are the one thing that can derail a play-centre plan. Combine it with a short walk in Lewes itself rather than dragging everyone back into town for a second paid activity.

Swimming when the rain settles in

Two pools make sense for a wet afternoon. The Triangle Leisure Centre in Burgess Hill has inflatables and a wave machine, while Wave Leisure Centre in Lewes has a large pool, inflatable sessions and a flume. Both are outside Brighton proper, so treat either as the main event of the day rather than an add-on.

Inflatable sessions run at set times rather than all day, so check the timetable for the date you have in mind before promising children a wave machine or a flume. Pack the swimming kit as a separate bag so wet costumes and towels do not soak everything else on the journey home. If you are staying in Brighton without a car, weigh up the train or bus connections before committing to Burgess Hill.

The Depot in Lewes: cinema, food and a dry seat

The Depot is Lewes's independent cinema and café-restaurant, opened in 2017 and showing recent releases alongside arthouse films. It is a genuinely good rainy-day option for adults and older children: a modern space where you can eat before or after the film, with back-row love seats for couples. Booking matters more here than at a multiplex, because independent screens are small and popular showings sell out when the weather turns.

The catch is timing. A film eats two hours plus a meal, so you get one solid anchor and little else from the day, which is fine if that is the plan. Pair it with a wander round Lewes only if the rain lets up; otherwise accept that the cinema is the outing and enjoy not being wet.

Staying in Brighton: cover without leaving town

If you would rather not leave the city, Brighton's covered shopping arcades and indoor markets give you a dry route through the middle of town, with cafés and tea rooms for shelter when a shower is at its worst. Our guide to shopping in Brighton maps out the main covered stretches, and the markets in Brighton are the other obvious stop when you want somewhere to browse while it pours.

Use the rain as an excuse to do the things you would skip on a sunny day. Afternoon tea in Brighton is a natural wet-weather booking, and the city's museums and galleries keep you indoors for an hour or two without spending much. If the forecast is mixed rather than hopeless, keep one outdoor option in reserve so a bright spell does not go to waste.

Budget-conscious visitors should know that some of the best indoor time in Brighton costs nothing beyond a coffee. Our list of free things to do in Brighton is the place to start when the rain is set in and you want a cheap afternoon, and it pairs well with a weekend in Brighton built around short hops between shelter.

Worth the train: bigger indoor days across the South East

When you have a full wet day and a rail ticket, the region offers some strong indoor anchors. Portsmouth Historic Dockyard covers five centuries of naval history, the Bodleian Libraries in Oxford run exhibitions and tours, Winchester Science Centre and Planetarium is built for hands-on family time, and Beaulieu's National Motor Museum gives you a proper indoor collection. Each is a day in itself, so pick one rather than trying to chain two together.

Transport planning is what makes or breaks these trips. Choose a site a short walk from the station so the soaking is limited to a few minutes, and pre-book ticketed attractions when rain is forecast, because popular indoor venues fill up in bad weather. Layered clothing and a light waterproof make the walk between station and entrance bearable without carrying half your luggage.

Shopping centres double as shelter, and the region has good ones. Eden Shopping Centre in High Wycombe and Gunwharf Quays in Portsmouth are both retail and leisure destinations, and Gunwharf Quays is a couple of minutes' walk from Portsmouth Harbour station with covered walkways, shops, restaurants and entertainment. That last detail is the wet-day clincher: you can arrive by train and stay dry for hours.

How to plan a wet day without wasting it

Build the day around one anchor and one backup, not a list of five stops. A wet day in Brighton goes wrong when you spend it walking between half-ideas, so choose the laser arena, the cinema or the pool first, then pick somewhere to eat close to it. If you have a car, larger attractions further out open up; without one, keep to the station-adjacent options.

Book the things with fixed capacity, such as cinema screenings, inflatable sessions and ticketed attractions, once rain is in the forecast. Everything else can stay loose. Carry a small umbrella and a foldable waterproof rather than a heavy coat, and wear shoes that survive puddles, because the walk between stops is what actually soaks you. If your trip is still taking shape, our guide to indoor activities in Birmingham shows the same logic applied to another city.

Plan Your Wet Day in Brighton

Start with who you are with. Older children and groups take LaserZone by the seafront; under-eights are better off at Monkey Bizness near Lewes; couples and adults get the best of a wet afternoon at The Depot in Lewes, with a film and a meal in one stop. Swimmers have two pools to choose between, and those willing to take the train can turn the day into a proper outing at Portsmouth Historic Dockyard or Gunwharf Quays.

Whichever you pick, confirm session times and booking requirements directly with the venue before you travel, since rain changes how busy indoor attractions get. Keep one low-cost, central backup in reserve, and the day will hold together even if the forecast turns worse than expected.
