Tuesday 22.7.25

Tomorrow, Tuesday, July 22, 2025, the United Kingdom can expect a generally unsettled and cooler day, particularly after a somewhat showery start to the week. While the precise conditions will vary slightly across different regions, the overarching theme will be one of moderate temperatures and a continued chance of light rain.

Across much of England and Wales, the day will likely begin with overcast skies and a lingering possibility of light rain, especially in western areas. As the day progresses, there might be some breaks in the cloud, offering glimpses of brighter spells, but these will likely be fleeting. Temperatures will be noticeably cooler than recent days, with highs generally reaching around 16°C in most parts. This will be a significant drop from the warmer conditions experienced earlier in the week, making it feel more like a typical British summer's day rather than a heatwave.

The wind will play a role in how the temperature feels, with a moderate breeze coming from the northwest, reaching speeds of approximately 11 mph. This northerly component will contribute to the cooler feel. Humidity levels are expected to remain high, around 86%, which could make the air feel a little damp, even when rain isn't actively falling.

For Scotland and Northern Ireland, similar conditions are anticipated. Expect a largely cloudy day with a continued risk of light rain or drizzle, particularly over higher ground and along western coasts. Temperatures will be slightly lower than in the south, perhaps only reaching 13-15°C in many areas. The northwestern wind will also be a feature here, potentially feeling stronger in exposed coastal regions.

The UV index for tomorrow across the UK is forecast to be low, around 2. This means that for most people, the risk of sun damage is minimal, and sun protection isn't a primary concern. However, it's always wise for those with very sensitive skin to take precautions if they plan to be outdoors for extended periods during any brighter intervals.

Looking ahead to the evening and overnight, the weather is set to become cloudier across the board. The chance of rain will diminish slightly as the day turns into night, with many areas experiencing a dry, though still overcast, evening. Overnight lows will dip to around 9°C, making for a relatively cool night.

In summary, Tuesday, July 22, will be a quintessential British summer's day – moderate temperatures, persistent cloud cover, and the ever-present chance of light rain, particularly during the daytime. It's a day for light layers and perhaps an umbrella, as the pleasant warmth of recent days takes a temporary back seat.
