July temperatures are our winter temps, but it's still a lovely place to come and stay. Today is currently 18 degrees at midday and expecting to get to 20, but there is cloud cover. If it was a clear day it would be around 22. over 4 years agoAnswered by Valla Beach Overnight Accommodation via WorldNomads.com
