The best time to visit Pembroke is during the summer months, from June to August, when the weather is warm and ideal for outdoor activities.During this period, the average daily temperatures range from a pleasant 20°C to 26°C, making it superb for exploring the Ottawa River and surrounding natural areas. The longer daylight hours also allow for more time to enjoy attractions such as the Pembroke Waterfront and local parks. This time of year is especially good for couples and families looking to enjoy water sports, hiking, or simply relaxing outdoors.Alternatively, the shoulder seasons of May and September offer cooler temperatures, typically between 10°C and 18°C, and fewer crowds. These months are excellent for travellers who prefer a more tranquil experience, perhaps exploring the area's heritage sites or enjoying the early autumn colours without the peak season bustle.
