The best time to go to Fort Severn is during the summer months, particularly from late June to early September, when the weather is mildest and wildlife viewing opportunities are at their peak.
During this period, temperatures are generally comfortable, ranging from the mid-50s to low 70s Fahrenheit (13-22°C), making outdoor activities more pleasant. The long daylight hours allow for extended exploration of the tundra and coastline. This time is ideal for wildlife enthusiasts, as polar bears are often seen along the coast before the ice forms, and various migratory birds are present.
For those interested in the unique natural phenomena of the region, late fall (October to November) offers a chance to witness the early stages of the freeze-up and potentially see polar bears gather along the Hudson Bay coast as they await the sea ice. However, temperatures will be significantly colder, often below freezing, requiring heavier winter clothing.
