Go for a picnic.
A few of weeks back myself and Toby found ourselves strapped for cash and not knowing what to do on a bright and sunny day. So he came up with the ingenious idea of going for a picnic at a local park. All we spent money on was petrol to get there and some food from ASDA for sandwiches, drinks, etc and the total for both of us came to £12! It's so lovely to just sit down, away from the internet and enjoy someone's company!
Go to the beach.
Another cheap idea! Grab a coolbox, some suncream and a bat and ball then you're ready to go! Even if it's not quite warm enough for a dip in the sea then you can still chill out with an ice cream and friends!
So this may be a more expensive idea but when the sun's out it's the perfect time to attempt Go Ape! I completed it a few years back and it's so much fun and hilarious to do with your family or friends. Just make sure you bring plenty of water with you!
Have a BBQ.
Why not have a barbecue if the sun decides to make an appearance? All you need to buy is a few packs of burgers, sausages, rolls and some drinks and you're good to go. You can even get your friends to bring some food each so it's even cheaper! Don't forget about UK weather though and be prepared for a spot of rain!
Have a car boot sale.
Instead of spending money on an expensive day in Brighton or London, why not earn by heading off to a car boot sale to get rid of some old stuff! You can sell some old winter clothes and even summer clothes that you've fallen out of love with!
