UK faces soaring temperatures as heatwave approaches

In the UK, hay fever sufferers are anticipating a challenging week, as the pollen counts are expected to surge across many regions. By the beginning of the week, very high pollen counts are predicted in the southeast and Midlands, with conditions worsening later in the week as the pollen spreads to the southwest, Wales, and northern England. Meanwhile, temperature forecasts indicate a possible heatwave, particularly in the south of England and London, where temperatures are expected to reach 30 degrees Celsius on Thursday and could rise to 32 degrees Celsius over the weekend. Weather patterns play a significant role in pollen levels and dispersion. The Met Office has highlighted that grass pollen counts are likely to be high when temperatures range from 18 to 28 degrees Celsius, especially if dry conditions are present. However, when temperatures surpass 28 degrees Celsius, pollen levels tend to drop. Sunlight is essential for pollen production; cloudy weather reduces pollen output as plants receive less light. Thus, the current forecast of high temperatures combined with sunny conditions is expected to contribute to increased pollen counts. As the conditions develop throughout the week, many Britons are preparing for outdoor activities. The anticipated warmth poses an excellent opportunity for family barbecues, festivals, and beach outings. Forecasters predict that some areas may relish heat levels that exceed those experienced in southern Europe, with south-eastern parts of the UK potentially registering temperatures hotter than in regions such as Portugal and southern France. The heatwave is likely to meet the official thresholds, which vary across the UK, as areas that hit the required temperature for three consecutive days confirm a state of heatwave. While many regions, including London and the East of England, are likely to see the highest temperatures, cooler weather is forecast for northern parts of the country. Temperatures in northern England are expected to remain in the mid-20s, while Scotland will experience highs of approximately 22 degrees. Although the heatwave may peak during the weekend, a decline in temperature is expected early next week as the high-pressure system pressures the continent shifts, leading to a possible reduction in heat and a return to more average June weather. Hydration and awareness are recommended during the heatwave, with health authorities advising caution particularly among vulnerable populations.
