The British summer is not the most predictable time of the year, however, as Cornwall is in the south you can expect average high temperatures of 17°C and lows of 12°C in June. With long daylight hours and only occasional rainfall, the warm weather in Cornwall in June creates perfect conditions for outdoor fun.

The Cornish coastline in the summer months is truly stunning, with rugged cliffs, sandy beaches, and blue waters offering breathtaking views. So, whether you're interested in hiking or simply relaxing on the beach, Cornwall has plenty to offer nature lovers and outdoor enthusiasts during this time of year.
