    Regional Diversity

    Diving in Canada is possible year-round, but the best conditions vary by region. For the west coast, the autumn and winter months (October to March) often provide the best visibility. The Great Lakes and the St. Lawrence River are best explored from June to September when the water is warmest. Newfoundland's season peaks in the summer months (July to September) for the best weather and visibility.
