The best time to visit Resolution Bay is during the summer months, from December to February, when the weather is warm and sunny, great for enjoying the Marlborough Sounds.During this period, you can expect long, dry days with temperatures often in the mid-20s Celsius, ideal for water activities like kayaking, swimming, and boating. The calm waters of the Sounds are particularly inviting at this time, making it easy to explore the secluded coves and beaches. It's also the peak season for local events and open-air dining experiences.For those who prefer a slightly quieter experience with pleasant weather, the shoulder seasons of spring (September to November) and autumn (March to May) are also excellent choices. You'll still enjoy mild temperatures and plenty of sunshine, but with fewer crowds. This can be particularly appealing for couples looking for a peaceful escape, as walking tracks are less busy and there's a more relaxed pace to the local activities.
