This period also offers the longest daylight hours, allowing for extended sightseeing and outdoor activities.Couples and families will find this season particularly appealing as it coincides with the peak whale watching season, offering excellent opportunities to spot various marine life. The summer also features numerous local festivals and events, including the Seafest, which celebrates Yarmouth's rich maritime heritage with parades, boat races, and live entertainment.
