Weather has nothing to do with internet use.And having a good time at the beach in southern Europe is something you can do after May usually.But anyway if you like spending some time on the internet and downloading,chating or posting is something you can do even in the middle of the summer,very few people spent all of their summer days at the beaches(lucky bastards).Summer job is the best job here,especially if you work in a place with a lot of tourists like Kos for example,a place with a lot of girls from Sweden(are there any guys from Sweden also?who knows )
