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
The Algarve, in Portugal’s Faro District, is known for a mild maritime climate and a coastline that offers a mix of sheltered lagoons and open Atlantic beaches. Sea temperatures vary through the year: in winter (December–February) waters are typically around 15–16°C, spring (March–May) sees a gradual rise to about 16–19°C, summer (June–August) brings the warmest conditions with averages near 19–23°C, and autumn (September–November) generally ranges from about 18–20°C as the sea slowly cools. Local variations occur between exposed western-facing shores, which can be cooler and subject to swell, and the more protected inlets and the Ria Formosa barrier-lagoon system, where shallower water warms more quickly and can be a few degrees higher than the open coast.
