Happy Morning !

A cool and unsettled spring day with light rain showers, especially in the morning and early afternoon. Expect a mix of cloud and some brighter intervals later. It will feel noticeably chilly for mid-May due to the northerly breeze.

  • Current Temperature (early morning): Around 7–9°C (45–48°F), feeling like 5–6°C due to wind and dampness.
  • Today's High: 13°C (55–56°F)
  • Tonight's Low: 5–7°C (41–44°F)
  • Wind: North-northwesterly, 8–13 mph (gentle breeze), with possible stronger gusts near showers.
  • Precipitation: Light showers likely, with a higher chance in the morning (up to 50–70% in places). Total rainfall around 1–2mm, not heavy but persistent in spots.
  • Humidity: High, 75–85%.
  • UV Index: Low (minimal sun protection needed).
  • Sunrise: ~5:11 AM | Sunset: ~8:44 PM (long daylight hours of over 15 hours — great for evening walks if drier later).

Hour-by-Hour Snapshot (approximate, based on latest forecasts):

  • Early Morning (6–9 AM): Cloudy, light showers or drizzle possible, 7–9°C.
  • Mid-Morning to Lunch: Showers continuing, temps rising slowly to 10–11°C.
  • Afternoon (2–5 PM): Showers easing from the north, some sunny breaks possible. Peak temperature near 13°C.
  • Evening: Drier with variable cloud, cooling quickly to 8–10°C.
  • Night: Mostly dry but cloudy, dropping to 5–7°C.

Why It Feels Cooler Than Expected

Mid-May averages in London are typically highs of 17–18°C. Today's forecast is 4–5°C below average, typical of a northerly airflow bringing fresher air from higher latitudes. Pollen levels remain low, which is excellent news for hay fever sufferers.

Extended Outlook (Weekend & Next Week)

  • Saturday 16 May: Similar feel — 14–15°C, sunny intervals mixed with cloud and a low chance of showers. Slightly less breezy.
  • Sunday 17 May: 15–16°C, risk of thundery showers in the afternoon.
  • Next Week: Warming trend! Highs climbing into the high teens by Monday and potentially reaching the low-to-mid 20s°C by mid-to-late next week with more settled, sunnier conditions.

This unsettled pattern is common in British spring — changeable but with improving prospects ahead.

Practical Precautions & London-Specific Tips

  • Clothing: Layers are essential — t-shirt/base layer, jumper/hoodie, and a lightweight waterproof jacket or raincoat. Scarf or light gloves might feel good in the wind.
  • Footwear & Mobility: Waterproof shoes or boots. London sidewalks (especially in parks or older areas) can get slippery. If using the Tube or buses, no major disruptions expected, but check TfL for any weather-related alerts.
  • Outdoor Plans:
    • Parks (Hyde Park, Regent’s Park): Fine for a brisk walk, but bring an umbrella.
    • Sightseeing (London Eye, Tower Bridge): Views might be moody and atmospheric with clouds — great for photos!
    • Cycling/Walking: Watch for gusts; visibility good but surfaces wet.
  • Health & Comfort: Stay hydrated despite the cool temps. If elderly, very young, or with respiratory issues, limit prolonged outdoor exposure. Air quality is generally good/low pollution.
  • Home/Garden: Any young plants may appreciate protection from the chill overnight. Good day for indoor London activities like museums if showers intensify.

Pro Tip for Visitors: Download the BBC Weather or Met Office app for hyper-local updates. London’s microclimates mean one borough can be drier than another.
