The UK Met Office has issued an amber weather warning for a heatwave expected to bring temperatures between 33°C and 36°C to several regions [1, 4].

This sudden spike in temperature poses significant public health and safety risks as the UK prepares for a bank-holiday weekend. The intensity of the heat may strain infrastructure and impact travel during a period of high activity.

The warning specifically covers the South West, South East, East of England, and parts of South Wales [1]. Forecasters said the extreme heat is due to a high-pressure front moving in from the Azores, known as an Iberian plume [2, 4].

Temperature projections vary across reports, reflecting the volatility of the weather system. Some forecasts suggest peak temperatures will reach 33°C next week [2], while others indicate a potential rise to 34°C [5]. Higher estimates suggest the possibility of 35°C in one region on Tuesday [4], with some reports citing a potential 36°C heatwave [4].

These conditions could lead to record-breaking May highs of 33°C in certain parts of the UK [3]. The Met Office said these conditions are expected to persist through the upcoming bank-holiday weekend and into the following week [2, 3].

Authorities are monitoring the situation as the Iberian plume returns to the region. The amber warning indicates an increased likelihood of medium-to-high impact weather, necessitating precautions for vulnerable populations and outdoor workers.

The arrival of an Iberian plume typically brings hot, dry air from southwest Europe, which can cause rapid temperature increases in the UK. Because British infrastructure is not designed for extreme heat, such events often lead to disruptions in rail services and increased pressure on the healthcare system due to heat-related illnesses.
