The best time to visit Weymouth is during the summer months, from June to August, when the weather is warm and sunny, great for enjoying the beaches and outdoor activities.During this period, you can expect average temperatures ranging from 20°C to 27°C (68°F to 80°F), with comfortable humidity levels. The longer daylight hours mean more time to explore the coastal areas and local attractions. This is ideal for families looking to make the most of their holiday, whether it's building sandcastles at Webb Memorial State Park or enjoying a picnic at Pond Meadow Park.For couples seeking a more relaxed experience, early September also offers pleasant weather with fewer crowds. The ocean temperatures remain mild enough for swimming, and you can still enjoy boat trips or strolls along the Fore River without the peak season rush. Many local restaurants and shops remain open, providing a comfortable and enjoyable atmosphere.While the summer is popular, it's also the busiest time, so booking accommodation and activities well in advance is advisable.
