The UK is on the cusp of its third heatwave in just four weeks, with temperatures set to soar above 25°C in several areas. The Met Office has issued red “very high” pollen alerts and issued warnings across multiple regions as the nation prepares for an intense weather event.
From Wednesday, July 9, the heatwave will intensify, with the highest temperature thresholds expected to be reached by Friday, July 11. According to the Met Office, a heatwave is officially declared when temperatures exceed 25°C for three consecutive days, with thresholds reaching up to 28°C in certain areas, including London. The agency is closely monitoring the situation as the UK continues to experience back-to-back heatwaves.
Seven Regions Under Red Alert as Extreme Temperatures Loom
The Met Office has issued red alerts for several regions, including parts of the West Midlands, South West England, and London, where pollen levels are predicted to be at their highest. These warnings are set to impact millions of people across the country, particularly those with hay fever.
The UK’s ongoing heatwaves pose significant health risks, not only because of the intense heat but also because of the high pollen count, which can trigger severe allergic reactions.
According to the Met Office, pollen levels will be particularly high in areas such as Greater Manchester and Wales, starting on Friday, July 11. This comes after a previous warning earlier in the week, which had already affected parts of the north and midlands.
For the many Britons suffering from hay fever, the ongoing extreme weather conditions present a dual challenge, making it difficult to cope with both the soaring temperatures and airborne allergens.
Health Risks of Prolonged Heat and Pollen Exposure
With nearly 10 million people in the UK affected by hay fever, the overlapping risks of high pollen counts and extreme heat could have serious consequences.
Health experts warn that the heatwave, combined with high levels of airborne pollen, could exacerbate respiratory conditions, particularly in vulnerable groups such as the elderly and those with pre-existing respiratory issues.
The Met Office has also stressed the importance of staying hydrated, using sun protection, and limiting outdoor activity during the hottest parts of the day. The rising temperatures are expected to peak in mid-July, leading to further disruptions in daily life and health concerns, particularly for those in the affected areas.
