In the summer and fall, the main storm track passes through the Bay of Fundy and northeast through the Strait of Belle Isle. Weakened tropical storms and hurricanes affect the southern portion of the province with at least one heavy rainstorm every one or two years. Winds blow predominantly from the west and northwest in the cold months and from the south and southwest in the warm months. With some exceptions, winds tend to be lighter farther away from the sea coast. Along the coast, sea breezes are frequent, especially in the early afternoon on warm, sunny days under light regional winds.
Local exposure is very significant.
Open, treeless localities and the tops and slopes of ridges and hills are often very windy. Also, local topography causes funnelling of the wind in many circumstances. Severe winds approaching hurricane force occur an hour or two each year along the coast, but are rarely measured at distances inland. On the other hand, in July it reports one of the lowest sunshine totals in Canada. Across New Brunswick in an average year, sunless days number 75 and sunny days number between 140 and 160.
