With the transition from winter to spring rapidly approaching, the weather across various regions of the UK is exhibiting notable fluctuations. Starting on Monday, March 17, 2025, residents from London to Gloucestershire will experience varied temperatures and weather conditions leading up to the spring equinox, which is set for March 20, 2025.
Monday kicks off as a relatively cold day, with temperatures hovering around 5°C early morning at 4:00 AM and dropping to approximately 2°C by sunrise. This chilly start brings along persistent cloud cover and a small chance of precipitation (around 10-20%) before 6:00 AM, as noted by forecasters. Winds will be originating from the north-east, gusting at approximately 6-7 mph, with humidity levels high between 85-87%.
Yet, midday is when the weather begins to warm. Temperatures are predicted to reach 9°C by noon, as clouds remain mostly present but with minimal chances of rain. Winds are expected to shift to the east-north-east, increasing slightly to around 9-10 mph. By the afternoon, temperatures will peak at about 10°C between 2:00 PM and 4:00 PM, with increasing sunny intervals breaking through the cloud cover. Humidity will decrease to around 46% as late afternoon approaches, offering some relief from the chilly morning.
Evening temperatures, unfortunately, will not hold. By 6:00 PM, the mercury will drop back to 7°C, with temperatures continuing to fall to 2°C by midnight. Gazing skywards, residents can expect to see clear skies with no anticipated rain, but temperatures may dip as low as -1°C by late evening, leading to a cold night for many.
Across the UK, as the week progresses, warmer temperatures are on the horizon. According to predictions from the Met Office, Thursday, March 20, 2025, will usher in warmer weather coinciding with the spring equinox, displaying temperatures potentially reaching 18°C in southern regions. Indeed, this temperature is about seven or eight degrees warmer than the average for this time of year, as underscored by reports from the BBC.
Meanwhile, the northern regions of Scotland will see significantly cooler forecasts, with Edinburgh and Belfast expecting temperatures around 10°C and 13°C, respectively. Notably, the warmest day recorded so far this spring was on March 9, 2025, when Crosby reached 19.7°C.
Spring is not just enthusiastic about warm weather; it also brings fluctuations. Residents can anticipate daily highs gradually increasing throughout the week. Tuesday, March 18, will see temperatures rising to about 12°C. Moving forward, Wednesday, March 19, holds promising conditions too, with the possibility of highs reaching 17°C, before peaking mid-afternoon on Thursday.
Regarding the future, weather patterns might appear even more favorable for warmer climes, refreshing the spring atmosphere across southern England, the Midlands, and parts of southern Scotland. Becky Mitchell, Met Office meteorologist, expressed confidence about the warm conditions for the spring equinox: “We’re definitely feeling spring-like,” she noted.
Throughout this brisk week, daytime highs across southern parts of the UK will be mostly pleasant, but the upcoming weekend may present challenges with forecasts hinting at rain on Friday evening, March 21, as colder air from the south and west manifests.
Meanwhile, Gloucestershire is poised to bask under the sun, with temperatures expected to reach around 20°C on March 20, beating levels seen previously in popular avian destinations like Ibiza and Corfu. This distinct rise is attributed to high-pressure systems, which typically encourage clear skies.
On Tuesday, March 18, temperatures are set to rise moderately to highs of about 12°C. But by the time Wednesday rolls around, the mercury could climb to approximately 17°C. Yet, as Gloucestershire's excitement builds for warmer weather, there's the possibility of light rain on Saturday morning, March 23.
Clearly, the week commencing March 17 is packed with weather shifts: residents must prepare for potentially chilly starts to their mornings, transitioning to sunnier late afternoons leading up to noteworthy warmth on the spring equinox.
Rain is not wholly absent as the week progresses, with forecasts predicting spread patterns arriving from the south. This leads to increased cloud cover, registering lower highs for the weekend finale.
Interestingly, London is similarly set to enjoy the seasonal shift. The capital will kick off Monday with temperatures around 10°C, compounded under cloudy conditions. Tuesday improves slightly, signaling sunshine breaking through the clouds, inching tops up to approximately 11°C, followed by more pronounced warmth on Wednesday, with peaks reaching 18°C.
The quintessential spring-like atmosphere materializes vividly by Thursday, March 20, with expectations of hitting 21°C—rather significant for early spring and under the dominion of high pressure.
Marco Petagna, another meteorologist, commented: “High pressure is bringing fine settled weather... Parts of eastern and southeastern England will see pretty much wall-to-wall sunshine.” This underlines the collective anticipation for thoroughly warm weather enveloping many UK regions.
To conclude, the week promises both crisp and warm moments as the arrival of spring heralds increased temperatures and longer sunny days across the UK. While there may be brief dips as rain approaches during the weekend, the initial days of spring carry the promise of warmer air and brighter skies, igniting the seasonal spirit.
