What a good plan B looks like
Rain. Ask every venue to show you its wet-weather plan before you sign: where the ceremony moves, where dinner goes, and whether that space holds all your guests. If the answer is "a marquee", ask who supplies it, by when it must be booked and what it costs. From late September onwards, treat the rain plan as part of the main plan.
Heat. In July and August, hold the ceremony later in the day, when the shade is longer. A terrace in shade at 19:00 can be fierce at 17:00, and a west-facing one stays in full sun until sunset. Plan shade and water for the moments guests stand around.
Wind. Corfu lies away from the strong meltemi of the Aegean. Its usual summer wind is the lighter maïstros, which sailing guides describe as building through the afternoon. It is welcome relief, but it moves veils, candles, arches and paper signs. The east coast is often more sheltered than the west.
For heat, sea, crowds and church dates side by side, see the best month to get married in Corfu. To check a specific day, including sunset and civil-ceremony days, use the wedding date checker. Beach set-ups have their own wind and permission issues: see beach weddings in Corfu.
Outside the season, November to March averages 13 to 17 days with rain a month (HNMS), so a winter wedding is best planned indoors.
