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
Cádiz sits on a narrow peninsula on Spain’s southwestern Atlantic coast, where the sea is tempered by the Gulf of Cádiz and the wider Atlantic influences. Water temperatures are mild compared with northern Europe but show clear seasonal variation: in winter (December–February) sea temperatures typically hover around 14–16 °C, in spring (March–May) they rise from roughly 15–19 °C, in summer (June–September) the warmest months reach about 20–24 °C, and in autumn (October–November) they fall back to roughly 18–21 °C. Local microclimates can produce small differences between sheltered city bays and exposed Atlantic stretches, and short-term changes occur with wind and currents, but these figures give a reliable seasonal guide for planning.

Swimming Conditions
Swimming and beach holidays in Cádiz are popular from late spring through early autumn, with the most comfortable bathing conditions in July and August when water temperatures are around 22–24 °C. City beaches such as La Caleta and Playa de la Victoria offer easy access and lifeguard services in season, while the longer sandy shores of the Costa de la Luz provide more space, windsurfing and kitesurfing opportunities where windier days create lively conditions. In shoulder seasons (May and October) many visitors swim or use wetsuits for longer sessions; winter swimming is possible for the hardy and for surfers seeking consistent waves. Water quality is generally good and safe for recreation, but swimmers should always take local advice about currents, tides and seasonal safety flags.
