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
Lake Heights is a residential suburb on the western shore of Lake Illawarra, near Wollongong in New South Wales, and is known for its outlook over the coastal lagoon rather than for a standalone inland lake. Water temperatures in the Lake Illawarra system vary with the seasons: in summer the sheltered lagoon commonly warms to around 20–24°C, making for pleasant paddling and swimming; autumn temperatures generally sit between 16–22°C as the water cools slowly; winter can see the coldest conditions, with surface temperatures typically around 12–17°C; and spring brings a gradual rise, usually about 14–20°C as daylight increases and the system warms. Local microclimates, freshwater inflow after rain and occasional exchanges with the ocean can cause short-term fluctuations within these bands.

Swimming Conditions
Swimming and beach-holiday opportunities around Lake Heights combine calm lagoon water and nearby ocean beaches. The lagoon offers protected areas ideal for families, casual swimmers and small craft, with shallow spots that warm faster in summer, while the ocean beaches a short drive away suit stronger swimmers, surfers and those seeking typical beach amenities. Water quality is usually good but can be affected by heavy rain and local runoff, so checking current advisories is advisable. During cooler months many people use wetsuits for comfort, whereas in summer swimwear is generally sufficient. Lifeguards, surf clubs and facilities are more commonly available at the ocean beaches during the warmer season, so beachgoers should choose locations according to their swimming ability and desired level of supervision.
