UK Heatwave Intensifies as Second Week Begins
UK heatwave to intensify again as it – The UK’s third heatwave of 2024 is expected to grow stronger this week, following a minor temperature decline on Monday. While some areas saw cooler conditions, the majority of England and Wales could once again hit 30°C, with forecasts hinting at localized spikes near 34°C or 35°C. Scotland and Northern Ireland may also hit their heatwave thresholds, as humidity rises across the country.
Health Alerts Remain in Effect
Amber and yellow heat health alerts, issued by the UK Health Security Agency (UKHSA), are active until 21:00 BST on 15 July. These warnings highlight the strain on healthcare systems, with elevated risks of heat-related deaths, especially among older adults and individuals with pre-existing conditions. The UKHSA notes that prolonged exposure to high temperatures could lead to significant impacts on social care services.
Are ‘heat spikes’ becoming more common?
Brisk north-easterly winds and reduced humidity, linked to a high-pressure system in northern Scotland, temporarily eased the heat in central and eastern regions. Monday’s temperatures in England and Wales are lower than recent days, yet some southern counties could still reach 30°C. For these areas, the streak of consecutive 30-degree days will extend into its second week. Northern Ireland and western Scotland may also meet their 25°C threshold.
Weather Shifts and Future Outlook
By midweek, a low-pressure system over France is anticipated to bring lighter easterly winds, shifting the UK toward slightly more humid conditions. Temperatures will climb again, peaking on Thursday. Forecasters predict 26°C to 27°C in western Scotland and Northern Ireland, while much of England and Wales could see highs around 30°C. Some models suggest isolated instances of 34°C or 35°C.
The UK has already recorded nine days this year with temperatures at 34°C or higher, surpassing the prior record set in 1976 and 2020 by two days. Nighttime temperatures are also forecast to rise, with a chance of “tropical nights” where readings remain above 20°C. This trend raises questions about the frequency of heat spikes in the coming months.
Risk of Wildfires and Drought Conditions
Extended heat and low humidity have heightened wildfire risks, particularly in England and Wales. Over the weekend, southern regions saw the fire risk classified as “exceptional” due to strong winds and dry conditions. While showers may slightly reduce the risk, it is expected to climb again in central and eastern England starting Wednesday.
Despite a few thunderstorms forecast for southern areas later this week, a substantial cooldown remains uncertain. Weather models suggest northerly winds this weekend could lower temperatures, though the extent of the drop depends on how quickly high pressure returns. This could prompt a resurgence of heatwave conditions, prolonging dry spells in many regions.
