We are goind to stay at the La Lanzada Beach ( Sanxenxo) from August 1 to 14. What the weather could be like at this time of the year. I looked at early July's prevision and it's discouraging. I also heard that the water is pretty cold there - how much it's cold, is it possible to bath at all? Also, is it possible to rent bicycles there, and are there any bicycle's rides? Thank you.
