Winds

Bermuda's wind patterns differ from those of most other coral reef areas in that the island is situated between the trade wind belt and the belt of the westerlies. Thus, the all year wind rose has only slight asymmetry. In summer, wind comes from all points, but south-easterlies predominate. In winter, however, south-westerlies predominate and northwesterly gales blow from North American frontal systems. The least common winds are northeasterly.

Surface winds of Bermuda are insignificant in their influence on the local weather since the islands are too low-lying to interfere with circulation on a large scale. However, winds influence local sea and swell conditions. Southwesterly winds cause frequent high surge and swells to "break" on the exposed southern shores.
