❌ As of today, the minimum water temperature ranges from 47°F (8°C) to 50°F (10°C). This is still cool water, suitable only for experienced swimmers or those accustomed to cold water. Swimming in such conditions is possible, but not recommended for prolonged periods. Extra caution should be taken during extended exposure, as the cold water can cause heat loss and lead to hypothermia. For added comfort, special clothing can be used.

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
In Concord, New Hampshire, the Merrimack River flows through the city, offering a scenic backdrop for outdoor activities. However, swimming in the river itself is not very common or recommended due to the river's varying water levels, currents, and water quality. During the summer months, the water temperature in the Merrimack River near Concord can range from 60°F (15°C) to 75°F (24°C), with the warmest temperatures typically occurring in late July and August. While these temperatures are more comfortable than colder spring or fall conditions, the water can still feel a bit cool for swimming, especially in the early summer.
The Merrimack River is more popular for other recreational activities, such as boating, fishing, and kayaking. There are designated areas in Concord for launching canoes or kayaks, and many people enjoy paddling along the river’s gentle stretches. The river's currents are manageable in most parts, making it suitable for those new to water activities.
For those specifically looking for swimming opportunities, there are alternative locations in and around Concord. Local swimming pools or nearby lakes, such as those at Bear Brook State Park, offer more traditional and safer options for swimming with warmer water temperatures. The Merrimack River, while beautiful, remains a better spot for river-based activities rather than swimming.
