Meteorologically, the British summer is a study in temperate instability. Lying at the confluence of tropical maritime, polar maritime, and continental air masses, the UK experiences a summer that is rarely hot by global standards—average July highs in London hover around a modest 23°C (73°F)—and never reliably dry. The jet stream, that high-altitude river of wind, dictates national mood; when it sits to the north, high pressure builds and a ‘barbecue summer’ is proclaimed. When it dips south, as it often does, Atlantic depressions parade across the country, delivering what the Irish poet Thomas Kinsella might have recognised as a ‘soft, classic summer’ of persistent, grey rain. This unpredictability is not a bug but a feature. It breeds a unique national obsession: the weather forecast. The British do not merely check the weather; they negotiate with it, planning weddings, festivals, and holidays in a perpetual state of conditional optimism.

In recent years, temperatures have soared, occasionally breaking the 40°C mark in Southern England.
