London's Hottest Day Forecast: Saharan Dust Arrives

London Braces for Hottest Day of the Year with Saharan Dust Phenomenon

London is poised to experience its warmest day of the year today, March 5, with temperatures forecast to soar to a remarkable 18°C. According to the Met Office, this marks a significant shift from the recent chilly and rainy spell, bringing above-average warmth for early March. The capital is expected to outshine popular Mediterranean destinations like Barcelona and Ibiza in terms of temperature, offering clear and bright conditions throughout much of the day.

Hour-by-Hour Temperature Breakdown

The Met Office has provided a detailed hour-by-hour forecast for London, highlighting a steady climb in temperatures:

  • 7am: 7°C, sunny
  • 8am: 7°C, sunny
  • 9am: 9°C, sunny
  • 10am: 11°C, sunny
  • 11am: 13°C, sunny
  • 12pm: 15°C, sunny
  • 1pm: 17°C, sunny
  • 2pm: 18°C, sunny
  • 3pm: 18°C, sunny
  • 4pm: 19°C, sunny
  • 5pm: 17°C, sunny

  • 11pm: 13°C, some cloud

This follows last week's peak of 18.7°C at Kew Gardens, with meteorologists suggesting today could potentially surpass that record. However, the warm spell may not last indefinitely, as there is a chance of thundery showers later in the month, according to weather experts.

Saharan Dust to Paint the Sky in Fiery Hues

Adding to the dramatic weather shift, a vast plume of Saharan dust is expected to drift over much of the country today and Friday. This phenomenon, driven by warm southerly air currents from North Africa, will transform sunrises and sunsets into spectacular displays of deep gold, amber, and burnt orange. The dust, which has travelled thousands of miles, is a mix of sand and mineral particles lifted from deserts.

While these visuals promise to be breathtaking, the dust can also leave dirty marks on cars and windows when combined with rain. The most vivid effects are likely in England and Wales as clearer, cooler conditions move in from the west. BBC Weather notes that this event stems from Storm Regina, which recently battered Iberia with heavy rain and strong winds, drawing up the southerly winds that carried the dust northward.

Weekend Outlook and Meteorological Context

Met Office meteorologist Honor Criswick provided further insights into the broader forecast. She explained that a band of cloud and rain, potentially heavy at times, will move eastwards from western areas, but eastern regions should remain mostly fine with long sunny periods until the rain arrives. Looking ahead, Friday will see cloudier conditions across much of England and Wales, while Northern Ireland and Scotland enjoy more sunshine, with highs of 11°C to 12°C.

The weekend is forecast to be a mix of patchy cloud and sunshine, with temperatures reaching 12°C to 13°C on Saturday and 14°C on Sunday. Criswick remarked, "It's the first week of meteorological spring so not a bad forecast," highlighting the seasonal transition. This warm spell offers a welcome respite from the recent unpredictable weather, though residents should stay alert for potential changes as the month progresses.
