The best time to visit Tagish is during the summer months, from late June to early September, for the most pleasant weather and outdoor activities, or from September to March for the best chances of seeing the Northern Lights.For those looking to enjoy the long daylight hours and warmer temperatures, July and August are ideal. During this period, the average daily temperatures are around 15-20°C, superb for exploring the Tagish Lake, fishing, hiking, and wildlife viewing. The midnight sun provides extended opportunities for outdoor adventures, and local operators offer organised boat tours and wilderness excursions.If your primary goal is to witness the spectacular Northern Lights, the darker, cooler months are best. From September to March, especially between October and February, the nights are long and clear, increasing the likelihood of seeing the aurora borealis. Temperatures can drop significantly, often below -20°C, so warm clothing is essential.
