Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.
Water temperature data for this location is gathered from various sources, including buoys and satellite sea and ocean surface maps provided by the NOAA agency. We also incorporate data from local authorities in each specific location worldwide to ensure more accurate temperature readings.

Monthly Water Temp Ranges
Annual Water Temperature Trend
Cushendall is a small coastal village on the Antrim coast of Northern Ireland with easy access to rocky bays and open sea along the North Channel. Sea temperatures here reflect the cool, temperate climate of the region and vary by season: winter (December–February) typically around 7–9 °C, spring (March–May) about 8–12 °C, summer (June–August) commonly 13–17 °C, and autumn (September–November) roughly 10–13 °C. These ranges can shift slightly with particular weather patterns or short-term Atlantic swells, and water feels colder than air temperatures, especially in the shoulder seasons. Local inshore waters are influenced by tides and wind, so conditions can change quickly.

Swimming Conditions
Swimming around Cushendall suits a range of preferences but is best approached with caution and preparation. The summer months offer the warmest water for traditional bathing, though temperatures remain cool compared with more southerly beach destinations; many visitors use wetsuits for longer swims or open-water events. Sheltered coves and pebble beaches provide opportunities for family paddling and rock-pooling, while more exposed stretches appeal to experienced sea swimmers and paddlers. Facilities in the village are modest, and marked lifeguard cover may be limited or seasonal, so it is advisable to check local advice, swim with others, be aware of tides and currents, and use appropriate thermal protection and safety equipment when venturing into the sea.
