Precautions & What to Wear Today

London weather loves to keep us on our toes! Here’s how to stay comfortable and dry:

  • Layer up: T-shirt or light sweater + jacket or waterproof coat. A fleece or hoodie will be useful in the breeze.
  • Rain protection: Compact umbrella or hooded waterproof jacket is a must. Showers should be light but can be persistent.
  • Footwear: Comfortable, water-resistant shoes or boots — pavements get slippery.
  • For commuters: Allow a bit of extra time if cycling or walking. Public transport should run smoothly, but watch for any surface water.
  • Health tips: Stay hydrated. If you have respiratory sensitivities, the damp air might feel heavier. Low pollen is a bonus today!
  • Outdoor plans: Hyde Park, Regent’s Park, or Thames walks are still enjoyable with proper gear. Bring a thermos for tea or coffee.

Pro tip: Keep sunglasses handy for any surprise sunny breaks — May light can be deceiving.

Best Activities for Today in London

  • Outdoor: Brisk walks in green spaces, people-watching with coffee in hand, or visiting markets (layered and prepared!).
  • Indoor alternatives: World-class museums (British Museum, Tate Modern), galleries, shopping at Westfield or Oxford Street, or cosy cafes and pubs.
  • Family-friendly: Science Museum or Natural History Museum — perfect for rainy spells.

Weekend Outlook

  • Sunday: Similar but slightly milder (high ~16–17°C), mix of cloud and possible isolated showers.
  • Monday onwards: Variable with showers at times, but temperatures trending warmer mid-week, potentially reaching the low-to-mid 20s°C later in the week. A warming trend is on the way!

Final Thoughts

Today’s weather is classic London spring — fresh, green, and a little moody. It’s not beach weather, but it’s ideal for exploring the city’s vibrant energy without the summer crowds. Dress smart, stay dry, and make the most of this beautiful (if damp) day!
