When I was much younger, the goal was to be in the water by May two-four weekend... the unofficial day summer begins. Never in the ocean mind, we swam in the lakes where the water warms earlier.
Although, when I lived on the Northumberland shore of the province, we were often able to swim in the ocean by the end of May; the water on that shore is always warmer because of the Northumberland Strait.
