Given the question: I know that the answer to the question "What record has not been broken for the UK?" is in "As with the rest of the UK, Southampton experiences an oceanic climate (Köppen Cfb). Its southerly, low lying and sheltered location ensures it is among the warmer, sunnier cities in the UK. It has held the record for the highest temperature in the UK for June at 35.6 °C (96.1 °F) since 1976.". Can you tell me what it is?
The answer is:
highest temperature in the UK for June at 35.6 °C (96.1 °F) since 1976
