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
New Quay is a compact coastal town on the Cardigan Bay coast of Wales, known for its harbour, rocky headlands and sandy coves. The marine environment here is influenced by Atlantic currents, so water temperatures are generally cool year-round. Typical seasonal ranges are roughly 7–9 °C in winter (December–February), 8–12 °C in spring (March–May), 14–18 °C in summer (June–August) when the sea reaches its warmest, and 11–14 °C in autumn (September–November). These figures can vary with short-term weather patterns and tidal conditions, and occasional warmer summers may push surface temperatures toward the upper end of the summer range.

Swimming Conditions
Swimming around New Quay offers a pleasant coastal holiday for visitors prepared for cooler water. During summer months many people swim from beaches and sheltered bays, although even then the sea is cooler than many Mediterranean destinations, so wetsuits are common for longer swims, surfing or paddleboarding. Tidal pools and rock pools provide opportunities for brief dips and safer shallow water for children, while calm weather makes sea swimming more comfortable. Local facilities, seasonal lifeguard coverage and clear signage at popular beaches help visitors assess conditions; swimmers should be mindful of tides, currents and sudden temperature changes. Combined with coastal walks, wildlife watching and water sports, New Quay is well suited to beach holidays for those who enjoy cooler-water swimming and varied seaside activities.
