The United Kingdom is currently experiencing its third notable heatwave of the summer season, leading to widespread elevated temperatures across the nation. Such prolonged periods of intense heat are typically caused by stationary high-pressure systems that settle over a region. These atmospheric conditions suppress cloud formation and prevent cooler air from entering, allowing an accumulation of warmth at ground level. As solar radiation continues to warm the surface under clear skies, temperatures can climb significantly and remain high for an extended duration. This meteorological setup explains the current conditions contributing to the exceptionally warm weather observed throughout the UK.
