Hello, I am planning to visit South Italy on July 20 for 11 days, including Sicily, Sorrento, Pompeii Ruins, Capri Island, Matera, Amalfi Coast and Alberobello (Trulli). From some web sites they stated the temperature was around 29C, but some said that it could be high at 35-40C. Please advise the approximate temperature of how hot it is.
I am planning to visit Blue Grotto of Capri Island for a boat trip. Is the weather in July be good as I am advised that sometimes if the sea level too high or bad weather , it will cause boat trip cancellation, but there is no indication which month is better for it. Thanks.
