*** Forecast - Our water temperature forecast

Actual near-shore water temperatures in North Beach can vary by several degrees from the values shown, particularly after heavy rain, strong southerlies, or prolonged windy conditions. Certain wind patterns can trigger upwelling, where cooler, deeper water is pushed to the surface and replaces the warmer top layer, leading to noticeable short-term changes in water temperature.

Our water temperature forecast is produced using a proprietary mathematical model that combines real-time measurements with long-term historical patterns, local weather conditions, wind strength and direction, and air temperature specific to each coastal region. To improve accuracy, we cross-check data from nearby locations and use multiple sources, including offshore buoys, satellite-based sea surface maps, and observations provided by local authorities.

Annual Water Temperature Trend

North Beach sits along Perth’s City Coast just north of Trigg, facing the open Indian Ocean with a mix of sandy shoreline and small reef sections that influence local conditions. Water temperatures here follow the typical Perth metro pattern and are comfortable for swimming for much of the year. In summer, from December to February, the sea usually ranges between 21–24°C, feeling warm and inviting on hot days. Autumn remains pleasant at around 19–22°C, while winter cools to roughly 16–18°C, which is brisk but still manageable for short swims. Spring brings a gradual warm-up again, generally sitting between 18–21°C as air temperatures rise.

Swimming Conditions

Swimming at North Beach is allowed and popular, especially during summer. The beach offers sandy entry points and some reef-protected areas that can create calmer water on the right day, making it suitable for confident swimmers. As with most of Perth’s coastline, conditions are often best in the morning before afternoon sea breezes increase chop and swell. In summer, most people swim comfortably without wetsuits and enjoy longer sessions in the water. Spring and autumn suit relaxed dips, while winter swimming tends to attract locals used to cooler water or those wearing light thermal gear. Overall, North Beach provides reliable swimming in clean Indian Ocean water, combining mild seasonal temperatures with a friendly, accessible suburban beach setting.
