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.
Annual Water Temperature Overview by Month
Monthly Water Temp Ranges
Annual Water Temperature Trend
San Fernando sits on the inner shore of the Bay of Cádiz in Andalusia, where the Atlantic influence keeps seawater temperatures moderate year-round. Typical annual values range from roughly 14 °C in the coldest months to about 25 °C at the summer peak. In winter (December–February) swimmers can expect waters near 14–16 °C, while spring (March–May) brings a gradual rise to around 16–20 °C. The warmest period is summer (June–August), when sea temperatures commonly reach 20–25 °C, making swimming most comfortable, and autumn (September–November) usually sees a gentle decline to roughly 18–22 °C. These figures reflect coastal conditions in the bay, which are somewhat warmer and less variable than exposed Atlantic beaches further south and west.

Swimming Conditions
Swimming and beach holidays in San Fernando are shaped by long sandy shores and a mix of sheltered bay waters and more open stretches. Many beaches have shallow gradients that warm quickly in summer and provide safe, family-friendly swimming when temperatures are above 20 °C, while the cooler months may appeal more to brisk open-water swimmers or those using wetsuits. During high season lifeguard services, beach amenities and local cafés are more readily available, and sheltered spots offer calmer conditions for children and casual swimmers. Those seeking more activity can find wind and swell suitable for watersports on nearby exposed points, but tides and wind can alter conditions quickly, so checking local reports is advisable before entering the water.
