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 Boa Vista is widely possible and attracts beach holiday visitors seeking warm water and long sandy stretches. Many of the island’s south and west-facing beaches offer calmer conditions suitable for casual swimming and snorkeling when winds are light, while exposed Atlantic heads and the northeastern beaches can produce strong surf and currents that are better suited to experienced swimmers or board sports. Lifeguard coverage is limited in places, so choosing sheltered coves or resort-managed beaches is advisable. Because water temperatures are generally comfortable, most people swim without wetsuits; activities such as snorkeling, diving, and wind- or kite-surfing also take advantage of the clear, temperate seas during the main tourist season.
