Typical, not a forecast. Reanalysis wind misses some local thermal winds, so a spot known for an afternoon breeze may do better than this.

About Harbour Authority of North Sydney Ballast Grounds
Known for sailing, by the OpenStreetMap map of the area. The shore faces E, so wind from the W blows out to sea (our estimate from the coastline).
Water about 9°C: 4/3 or 5/4, boots and gloves. Typical sea temperature for the time of year, not a forecast.
A harbour, as OpenStreetMap maps it, on a shore facing E. Wind from the E blows onshore, wind from the W blows out to sea, and wind from the S or N runs along the shore. It is sheltered to the open sea. We found no boat hire, sailing school or club within 10 km on the map, so bring your own boat here. The sea is about -1°C in March, its coldest month (5/4 or 6/5, hood, boots and gloves), and 19°C in August, its warmest (2 mm shorty). The town to stay in is Louisbourg.
The score is the conditions only: the journey, the price and the partners never change it (how we score, how we earn).
