Corinth weather by month
Corinth stands at the gateway to the Peloponnese, about an hour's drive from Athens, next to the famous canal. Most Israeli visitors stop for a few hours on the way to Nafplio or Loutraki, so the weather matters mainly for knowing when it is pleasant to stand on the bridge over the canal and walk the ancient site.
