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
Cochichewick Lake in North Andover, Massachusetts, experiences pronounced seasonal changes in surface water temperature. In winter the lake commonly approaches freezing, with surface temperatures around 32°F (0°C) where ice forms; dissolved water below the ice can remain just above 32–40°F (0–4°C). Spring warming typically brings surface values into the 40–60°F range (4–16°C) as stratification begins. During summer, on warm, calm days the upper water often reaches the mid-60s to upper-70s °F (about 18–26°C), though deeper or shaded portions stay noticeably cooler. In autumn the surface cools back toward 50–65°F (10–18°C) as turnover mixes the water column. Local weather, wind, and depth profile influence these numbers, so short-term readings can vary.
Swimming at Cochichewick is generally not permitted because the lake functions as a managed reservoir and is subject to municipal water-supply and safety protections. Restrictions are intended to protect drinking-water quality, reduce contamination risks, and limit liability and hazards such as cold, uneven bottoms and sudden drop-offs. Ice-related dangers in winter also make recreational swimming unsafe. Visitors should heed posted signage and town rules; for designated swimming, nearby public beaches and pools maintained for recreation are safer and regulated alternatives.
