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 Conditions
Swimming around Valletta is more about rocky harbours, bathing terraces and short transfers to nearby sandy beaches than long stretches of city coastline. The Grand Harbour and Marsamxett Harbour have concrete steps and small lidos where locals and visitors enter the sea, and the clear visibility supports snorkeling around the harbour edges and nearby headlands. For traditional beach holiday amenities, short ferry or bus connections from Valletta reach resort areas such as Sliema and St Julian’s with promenade access and beach clubs, while longer transfers lead to Mellieħa Bay and Golden Bay for sandy bathing. Boat trips, coastal swims and diving excursions are readily available from the waterfront, though swimmers should choose designated bathing spots or supervised beaches when boat traffic or currents are present.
