Annual Water Temperature Trend

Souris, on the eastern shore of Prince Edward Island facing the Northumberland Strait, sits beside shallow, sandy coastal waters that warm and cool quickly with the seasons. Typical water temperatures range from around 0–2 °C in winter when sea ice and cold currents are common, rising to roughly 2–10 °C in spring as the Gulf begins to warm. In summer the Northumberland Strait often reaches its warmest values, with water generally between about 15–24 °C depending on weather, tide and sheltered versus exposed locations. Autumn sees a steady decline, with waters typically cooling to the order of 8–15 °C by September into October. Local conditions and year-to-year variation can shift these bands by a few degrees; shallow bays and sheltered coves warm faster than open ocean exposures.
