Nantucket is hit or miss in June. It can be 75F and sunny or it can be 55F and rainy. Let's hope for the former!!! But regardless, please try to plan accordingly. For the wedding, we will be directly on the beach and ocean breezes will affect the temperature.

Men should wear a traditional suit and tie/bowtie. As for women, short, tea, or long cocktail dresses are appropriate. Keep in mind, the ceremony will take place on the beach in the sand. Keep in mind the beach can be windy and chilly in June if the sun isn't shining, so bring a pashmina to keep yourself comfortable during the ceremony.
