London - higher than the previous record for 2025 of 29.4C in Suffolk on 13 June. Suffolk became the first place in the UK to officially enter a heatwave on Thursday after temperatures passed 27C for the third day in a row. Amber heat health alerts are in place across the whole of England until 09:00 BST on Monday, as the UK Health Security Agency (UKHSA) warned that increased pressures on health and social care services were likely. The heat is expected to build towards a high of 33C on Saturday, with central and eastern England seeing the peak temperatures. Temperatures will widely be between 27C and 30C on Thursday across east Wales, the Midlands, and East and South East England, with a few locations around Greater London and the home counties expected to join Kew in the low 30s. Elsewhere, temperatures will climb to between 23C and 27C though along the coast it will feel cooler, with temperatures sitting about 20C. For a heatwave to be declared by the Met Office a threshold temperature needs to be met for at least three consecutive days. (BBC)
