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
Nhulunbuy, on the Gove Peninsula in Australia’s Northern Territory, lies in a tropical monsoonal zone where sea temperatures remain relatively warm year‑round but vary with the seasons and local conditions. Coastal waters close to town and in shallow bays tend to warm more quickly, while exposed ocean swells are often a few degrees cooler. During the wet season, roughly November to April, surface temperatures commonly sit around 28°C to 31°C. In the dry season, from about May to October, water cools somewhat, typically ranging from 24°C to 28°C. Tides, local currents and depth can shift those numbers by a couple of degrees on any given day, and calm, sheltered coves will feel warmer than open reefs.

Swimming Conditions
Swimming and beach recreation around Nhulunbuy can be very rewarding, particularly in the dry months when seas are clearer and conditions calmer and the 24°C to 28°C water is comfortable for extended swims. There are sheltered bays and reef fringes suitable for snorkeling and informal beach holidays, with opportunities to see coral and marine life close to shore. However, this is a remote tropical coastline with limited patrolled beaches and important safety considerations: the wet season brings stinger (jellyfish) risk and reduced visibility, and saltwater crocodiles can be present in estuaries and some coastal waterways, so local advice should always be followed. Visitors seeking the most reliable swimming conditions usually plan trips in the dry season and prepare with reef‑safe sunscreen, suitable swimwear, and awareness of local warnings and tides.
