Annual Water Temperature Trend

Millport, on the Isle of Cumbrae off the Firth of Clyde in Scotland, is a small coastal town known for its sheltered bay and accessible shoreline. Sea temperatures around Millport follow the typical pattern of the west coast of Scotland: winter water commonly falls to around 5–8 °C, spring sees a gradual rise into the high single digits and low teens (roughly 8–12 °C), and summer months usually bring the warmest conditions, with surface readings typically between 14–17 °C and occasionally slightly higher in sheltered shallows on calm days. Autumn cooling begins in September and October, with temperatures generally moving back toward 10–12 °C and then down into single figures by late autumn and winter. Local variations occur with tides, winds and sunshine, so short-term temperatures can differ from seasonal averages.
