*** Forecast - Our water temperature forecast
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.

Location & Local Information
Mérida, in the Extremadura region of Spain, lies near several rivers and small reservoirs whose water temperatures vary with the seasons and local conditions. Typical surface temperatures in spring range from about 12–18 °C (54–64 °F) as waters warm after winter. In summer, shallow lakes and slow-moving river stretches commonly reach 20–26 °C (68–79 °F), and on very hot afternoons they can be a few degrees warmer. Autumn sees a gradual cooling to roughly 14–20 °C (57–68 °F), while winter surface temperatures often fall to around 8–12 °C (46–54 °F). Actual temperatures depend on depth, shading, inflow, and recent weather; deeper or faster-flowing sections remain colder than shallow, sun-exposed basins.
Swimming opportunities around Mérida exist but are subject to local rules and safety considerations. Some reservoirs and protected natural sites restrict bathing to preserve water quality, archaeological values, or wildlife, while designated recreational areas and nearby reservoirs permit swimming and provide facilities. Safety issues — currents, submerged hazards, lack of lifeguards, and water quality — influence whether swimming is allowed at a given spot. Visitors and locals are advised to check signage and municipal regulations before entering the water and to prefer authorized beaches and monitored areas when available.
