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.

Swimming and beach holidays on Formentera suit a range of preferences, from family-friendly paddling to more active snorkeling and paddleboarding. The shallow, sandy bays provide comfortable entry for casual swimmers during June to September when waters are warmest, while May and October can still be pleasant for those who don’t mind slightly cooler water. Experienced open-water swimmers and those seeking quieter seasons can swim year-round if prepared for cooler temperatures in winter and a wetsuit in the coldest months.
