Gragnano is warm all year, but especially hot in the summer. Luckily, a sea breeze called the Mistral blows into town from the Gulf of Naples. It is present all year but usually strongest during the winter and spring seasons.
The wind might annoy locals with bad hair days, but it's also the reason Gragnano can produce such great pasta. You can make fresh, homemade pasta every single day, but if it's too humid, you'll end up with a gooey mess. The cool and dry air that blows in helps dry the pasta being made in Gragnano.
