Fog is a type of cloud that forms at ground level, reducing visibility and making navigation challenging. In Nova Scotia, fog can occur at any time of the year, but it's more prevalent during the spring and summer months when warm air meets the cooler ocean waters. The province's unique geography, with its extensive coastline and numerous bays, inlets, and islands, creates a microclimate that fosters fog formation.
