*** 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

Tomarata Lake, in the Auckland Region north of Warkworth, is a shallow dune lake surrounded by farmland and native vegetation. Its modest depth means water temperatures respond quickly to seasonal air changes. In winter, surface temperatures are generally around 11–15°C. During spring, the lake gradually warms to approximately 15–19°C as days become milder. In summer, particularly in January and February, shallow near-shore areas can reach about 21–26°C on hot, settled days. By autumn, temperatures usually ease back to between 16 and 20°C. Wind can mix the shallow water, influencing surface warmth and clarity.

Swimming Conditions

Swimming is allowed at Tomarata Lake, and it is a popular local spot during the warmer months. The most comfortable conditions are typically in mid to late summer when water temperatures exceed 20°C and winds are light. However, as with many shallow lakes, water quality can vary depending on rainfall, nutrient levels and seasonal algal growth. Swimmers should use established access points and check current water quality information before entering the water. Choosing calm weather conditions and avoiding swimming after heavy rain helps ensure a safer and more enjoyable freshwater experience.
