The Wind Off the Small Isles Only two days after arriving there, Cora decides she wants to buy a house. While driving around the island they reach Playa Blanca and Cora sees just the house she is looking for. She sends Perdita to ask who owns it. Perdita, after getting no answer at the front door, meets Michael in the grounds who is supervising building work. There is a mention of Julian Gale from Stewart's earlier novel, "This Rough Magic". The Wind Off the Small Isles The Wind Off the Small Isles is a novella by Mary Stewart, first published in 1968. Unlike her other works,
Beaufort scale law relating wind velocity to Beaufort force. Wave heights in the scale are for conditions in the open ocean, not along the shore. The wind speeds in different units are not mathematically equivalent; e.g. 12–19 km/h is not equivalent to 8–12 mph, and both are not equivalent to 7–10 knots. The reason is that the Beaufort scale is not an exact nor an objective scale. It was based on visual and subjective observation of a ship and of the sea. The corresponding integral wind speeds were determined later, but the values in different units were never made equivalent. The scale
