Europe honeymoon rec

Hi! My fiancé and I are getting married next summer. Because of his residency schedule we’re going to have to do the honeymoon a couple months after our wedding in early June. Does anyone have location recommendations for a honeymoon in late summer? We’re thinking somewhere with a beach / warmer weather. Is Greece still warm during late summer? Any recs welcome (even if they don’t have a beach ie Paris) !!! TYIA
