The bad news is that you can't rely on the British summer weather and as we are expecting to get more rain in July and August it makes sense to cancel that bbq you have been planning for with aunt Meredith and uncle Trolley and take a trip down to the Greek islands.
Greece has a plethora of islands to choose from (around 1200) each and every single one of them unique in a different way. In addition it is probably cheaper than spending a week in Scanthorpe or Bognor. Two friends who have just returned back from Skiathos (The Sporades) report great weather, cheap food and wine and no problems having to reserve your sun bed every morning.. wonder what they both mean?
So help the Greek resistance stand up to the Troika and visit Greece, you will not be disapointed. I recommend non tourist destinations like Skiathos, Skopelos, Samos, Chios or Mykonos. Go for it!
