Water Temperature: Daily Trends, Historical Records, and Forecast

❌ As of today, the minimum water temperature ranges from 54°F (12°C) to 60°F (15°C). The water is significantly warmer, and swimming becomes possible for most people. However, caution may still be required for prolonged stays in the water, as extended exposure can cause discomfort. This is a suitable temperature range for short swims and for those accustomed to cooler water. For more comfortable swimming, it is recommended to use proper gear.

It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

Annual Water Temperature Trend

Largs, on the Firth of Clyde in Scotland, sits on a sheltered stretch of the west coast where sea temperatures remain cool year-round. Typical winter values (December–February) are commonly around 6–8 °C, with spring (March–May) gradually rising from about 7–11 °C. The warmest period is in summer (June–August), when waters usually reach 12–16 °C and can occasionally touch 17 °C on particularly warm late‑summer days. Autumn (September–November) sees a steady decline, often between 11 °C in early autumn down to around 8–10 °C by November. Tidal movement in the firth and variable weather can produce rapid changes in local conditions, so these figures should be seen as general seasonal guides rather than precise daily values.
