Water Temperature in Lake Wivenhoe: Daily Trends, Historical Records, and Forecast
⚠️ A lake temperature of 15 to 20°C is considered cool to comfortable for swimming in Australia. On warm days with light winds, this range allows for relaxed swimming, especially in shallow or sheltered areas. Comfort depends strongly on air temperature and sunshine, as cooler or overcast weather can still make the water feel chilly. This range is common during spring and early summer.

*** Forecast - Our water temperature forecast
Actual lake water temperatures may differ from the reported values by several degrees, particularly during periods of strong winds or rapid weather changes. Wind can mix surface and deeper layers in a lake, bringing cooler water to the surface, while shallow areas may warm more quickly under direct sunlight. Air temperature, sunshine, and cloud cover strongly influence how quickly a lake heats up or cools down. These factors can lead to noticeable temperature variations across different parts of the lake.
Our forecast is based on a proprietary mathematical model that considers real-time lake temperature observations, historical trends, seasonal cycles, wind strength and direction, and region-specific air temperature. To enhance accuracy, we also incorporate data from nearby monitored locations and comparable lakes within Australia.

Location & Local Information
Lake Wivenhoe sits west of Brisbane and is a large freshwater storage surrounded by bushland and open country. Water temperature here follows the subtropical climate of south-east Queensland. In summer, from December to February, the lake usually warms to around 24–28°C, and in sheltered bays it can feel even warmer during extended hot weather. Spring and autumn are comfortable, with water temperatures generally sitting between 20–25°C. Winter brings cooler conditions, but the water rarely feels cold, typically ranging from about 16–20°C, especially in deeper sections where temperature changes are slower. Wind and changing water levels can affect how warm the surface feels from day to day.
Swimming Conditions
Swimming in Lake Wivenhoe is allowed and does take place, particularly in summer when the water temperature is most inviting. Many people enjoy swimming from the shore or from boats in quieter areas, where the water is calm and clear. During the warmer months, the temperature is suitable for proper swimming rather than just a quick dip. However, the lake is primarily a drinking water supply, so activities are managed and there are no formal swimming beaches. Water levels can change quickly, and submerged timber or uneven banks are common. With sensible spot selection and calm conditions, swimming can be enjoyable, but it’s best done with care and awareness of the lake’s changing environment.
