Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 41°F (5°C) to 47°F (8°C). This water temperature is still quite low, and swimming in such conditions may only be comfortable for hardened individuals. It is recommended to limit the time spent in the water to avoid hypothermia. For those not accustomed to cold water, it is better to refrain from swimming. However, if you decide to enter the water, it is advisable to wear a warm wetsuit for protection against the cold. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** Forecast - Our water temperature forecast
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.

Location & Local Information
Dalrymple Lake, located on the western edge of the City of Kawartha Lakes, is primarily a shallow, spring-fed body of water, which allows its temperature to shift considerably with the seasons. Due to the hot inland summers, the lake warms significantly, with surface temperatures typically reaching a comfortable range for swimming, likely peaking between 20∘C and 24∘C (68∘F to 75∘F). In the cold winter months, the lake freezes completely, with water temperatures near the freezing point, generally ranging from 0∘C to 5∘C (32∘F to 41∘F).
Swimming is widely permitted and popular throughout Dalrymple Lake, confirming its use as a major recreational and tourism destination. Local resorts and cottage areas feature designated beach zones for water contact. However, the lake is prone to mid-summer algae blooms and, due to its shallow nature, has significant aquatic plant growth, which can impact swimming enjoyment and lead to water quality concerns. While swimming is generally safe, the lake's public access points and beaches are typically unsupervised, meaning all swimming is undertaken strictly at one's own risk.
