Annual Water Temperature Trend

Bantry, on the southwest coast of County Cork in Munster, sits at the head of Bantry Bay and benefits from a maritime climate that keeps sea temperatures relatively moderate for its latitude. Water in and around the bay tends to be cold by summer-swimming standards but milder than more exposed Atlantic coasts thanks to coastal shelter and the influence of the North Atlantic current. Typical seasonal water temperatures range roughly from 8–10 °C in winter, 9–13 °C in spring, 13–17 °C in summer and 11–14 °C in autumn, with sheltered inlets and shallow areas often a degree or two warmer on calm days. Conditions can vary with wind, tidal flow and recent weather, so short-term changes are common.
