Bay of Plenty enjoys a mild climate throughout the year which makes it an attractive destination no matter when you decide to visit. However, if you prefer warmer temperatures for outdoor activities like swimming or hiking, the summer months of December to February are ideal. Spring (September to November) and autumn (March to May) offer pleasant weather and fewer crowds, making it a great time for exploring the region's natural beauty and attending local events. Winter (June to August) brings cooler temperatures but also offers unique experiences such as whale watching.
