7. Take an umbrella
London weather is notoriously unpredictable. As the locals would say, it isn’t London if it isn’t raining. But, people are genuinely delighted when the sun is out. Londoners get used to carrying both an umbrella and sunglasses to be prepared for rain and sunshine.
Save shopping for rain gears in London by bringing your own collapsible umbrella or raincoat. At the very least, check the weather forecast on the BBC before you leave your hotel room every day. If it starts raining cats and dogs, you can also duck into a shop, café or museum and get out of the rain.
