Hi David,
We live in Cornwall and the forecast for the end of the month is much better and this should reflect the weather in Brittany. We are off as well on the 10th Aug and are praying for good weather. With 3 children under 6 and a site next to the beach we will need some sun!!! We are staying at La Baie in Southern Brittany, what about you? Have a great time. Denise
