I want to know the answer to the following question:
In what month and year did Plymouth see its highest temperature between 1971 and 2000?
All the background I'm provided with is that "Typically, the warmest day of the year (1971–2000) will achieve a temperature of 26.6 °C (80 °F), although in June 1976 the temperature reached 31.6 °C (89 °F), the site record.". Is that enough to answer the question?
