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
Melbourne sits on Port Phillip Bay and lies close to the cooler waters of Bass Strait, giving its coastal waters a temperate character. Seasonal water temperatures vary across the region: in summer they typically reach about 18–23 °C in sheltered bay areas and can be slightly cooler along exposed southern coasts, while autumn sees a gradual fall to roughly 15–20 °C. Winter brings the coldest conditions, with coastal waters commonly between about 10–14 °C, and spring temperatures usually climb from about 12–18 °C as the season progresses. Local conditions such as wind, currents and the difference between bay and open-coast beaches produce day-to-day variation, so swimmers often experience noticeably warmer water on calm sunny days and colder water during onshore winds or after cold fronts.

Swimming Conditions
Swimming opportunities around Melbourne suit a range of preferences, from protected bay beaches ideal for families to surf beaches that attract surfers and stronger swimmers. Inner-city spots and suburbs have popular, patrolled beaches in summer that offer safer swimming areas, while the Mornington Peninsula, Phillip Island and coastal stretches toward the Great Ocean Road provide both gentle bays and rugged surf breaks within a short drive. Many swimmers and triathletes use sea baths and enclosed swimming areas for a more controlled experience, and public pools offer an alternative when ocean conditions or temperatures are uninviting. Because water tends to be cool outside midsummer, many people choose shorter swims or wear wetsuits for longer sessions; lifeguard patrols and local signage help guide safe choices at different sites.
