Along with the rest of South West England, the Mendip Hills have a temperate climate that is generally wetter and milder than the rest of England. The annual mean temperature is about 10 °C (50 °F) with seasonal and diurnal variations, but the modifying effect of the sea restricts the range to less than that in most other parts of the United Kingdom. January is the coldest month, with mean minimum temperatures between 1 °C (34 °F) and 2 °C (36 °F). July and August are the warmest, with mean daily maxima around 21 °C (70 °F). In general, December is the dullest month and June the sunniest. The south-west of England enjoys a favoured location, particularly in summer, when the Azores High extends its influence north-eastwards towards the UK.
