The UK is bracing for more variable weather in the latter half of the season, with long-range predictions indicating incoming rain. Despite this, temperatures are likely to stay higher than typical averages throughout July and August, meaning the threat of heatwaves persists.
So far, this summer has shattered records, some dating back to the legendary heat of 1976. Prolonged dry spells have impacted southern England, leading to water restrictions and wildfires fueled by parched vegetation.
Weather models remain indecisive. DTN data suggests low pressure may bring increased moisture to Northern Ireland and Scotland. Conversely, the Azores high pressure system could act as a buffer, maintaining drier conditions. The Met Office anticipates a potential shift in high-pressure dominance by late July, possibly leading to scattered showers and storms, before August returns to changeable, yet warm, conditions.
Long-term forecasting involves significant uncertainty, as atmospheric patterns are inherently chaotic. However, experts confirm that the recent extreme weather is increasingly becoming the new norm due to human-influenced climate warming, which has accelerated UK temperature increases by approximately 0.25C per decade since the 1980s.
This year has marked a unique climate event, with temperatures reaching 35C across three distinct months. Factors such as persistent high pressure, dry soil conditions, and elevated sea-surface temperatures have collectively intensified these heat events.
