Prepare for a sustained period of hot weather, as a heat wave is defined by the Met Office as when a location records at least three consecutive days with daily maximum temperatures meeting or exceeding a specific threshold, which varies by UK region.
What is a heat wave in the UK?
The Met Office declares a heat wave when a location logs three days in a row above its local temperature threshold. For example, in London the threshold is 28°C, while in parts of Scotland it is 25°C. This official definition helps authorities issue public health warnings and trigger emergency response plans.
How should I stay safe during a heat wave today?
Keep your home cool by closing curtains during the day, stay hydrated with water, and avoid strenuous activity between 11am and 3pm. Check on elderly neighbours and those with health conditions, as heat stroke and dehydration can develop quickly. For local conditions, see our Birmingham weather or Glasgow weather pages.
What about the heat wave song and other cultural references?
The term “heat wave” appears in music, film, and gaming. The “heat wave song” often refers to Martha and the Vandellas’ 1963 Motown classic “(Love Is Like a) Heat Wave”, while the “heat wave movie” is a 2022 thriller starring Kat Graham. In gaming, a “heat wave pokémon” move is a Fire-type attack introduced in Generation III. Internationally, a “heat wave india” event in 2024 saw temperatures exceed 50°C in parts of Rajasthan, highlighting global climate extremes.
How hot is a heat wave temperature in the UK?
A heat wave temperature in the UK typically means daytime highs of 28–32°C in southern England and 25–28°C in northern regions. The Met Office issues amber or red warnings when temperatures pose a risk to health.
What causes a heat wave weather event?
A heat wave weather event is usually caused by a high-pressure system (anticyclone) that traps warm air over the UK, often drawing hot air from continental Europe or North Africa. Climate change is making these events more frequent and intense.
