Brits don't let 'typical wet British weather' get in the way of a staycation

A survey of 2,000 adults in the UK, as part of the study by Sykes Holiday Cottages and Wyn Evans found that 72% of people don’t let typical wet British weather get in the way of a staycation.

On top of that 61% said it wasn't a British holiday if it didn’t rain. 

When it came to activities while on holiday in the UK sightseeing (53%), strolls along the pier (37%), and tucking into fish and chips (30%) were among the most popular activities people would do regardless of the weather.

Sykes chief executive, Graham Donoghue, said: “Rain is often part and parcel of a UK holiday, but our latest research shows that wet weather isn’t necessarily a dampener on people’s staycation experiences.

He continued: “You don’t need to shy away from the wet weather while on staycation – in fact, you may find you get to know your chosen location better than you would’ve in the sunshine by spending more time with the local community in pubs, restaurants, and local eateries.”


Former BBC weather presenter, Wyn Evans, added: “I love that even in the rain, holidaymakers will still embrace a Great British staycation.

“Us Brits won’t let a bit of wet weather keep us indoors, and I’d argue some activities can even be better with a few rain drops.

“Despite my experience as a weather presenter, the exact detail on rain, especially showers can be hard to predict, so hopefully this analysis will give Brits some idea of what to expect and plan for if they’re heading to a seaside location this year.”
