The UK is bracing for a warmer-than-average summer, as indicated by the Met Office's three-month outlook released on June 1. This forecast suggests a heightened likelihood of heatwaves and heat-related impacts, following a record-breaking May heatwave that saw temperatures soar to 35.1°C in Kew Gardens, London. The outlook indicates that each month of summer could experience above-average temperatures, with potential for significant heat spikes. However, predictions regarding rainfall are less certain, with varying forecasts suggesting either drier conditions or average to above-average rainfall. Despite most UK reservoirs being at or above seasonal averages after a wet winter, parts of southern and eastern England suffered from extremely low spring rainfall, causing some rivers to reach notably low levels. Water supply pressures are already evident, with Thames Water reporting a surge in demand during the recent heatwave. Seasonal forecasts are crucial for planning by healthcare and energy sectors, although they do not guarantee consistent conditions throughout the summer.
