The weather on the Amalfi Coast in July is hot. Prepare to be greeted by warm air temperatures ranging from 23°C to 31°C (73°F to 88°F) as July takes the reins. The inviting sea follows suit, offering a refreshing 24°C to 27°C (75°F to 81°F) as a sanctuary from the heat. See our guide to the best time to go to Italy.
