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
Fort Smith, Arkansas, is located along the Arkansas River, a major waterway that flows through the region, offering some recreational opportunities, including swimming. The water temperature in the Arkansas River can fluctuate depending on the season. During the warmer months, from late spring to early fall, the water temperature typically ranges from 70°F (21°C) to 80°F (27°C), which can be quite pleasant for swimming, especially when temperatures in Fort Smith can rise above 90°F (32°C). However, the river's current can be strong in certain areas, which means swimming might be more challenging or dangerous in parts of the river where the flow is faster.
In the cooler months, the temperature of the Arkansas River drops, with water temperatures ranging from 40°F (4°C) to 50°F (10°C) in winter. These colder temperatures make swimming less inviting, as the water can feel too chilly for comfortable swimming. The current also tends to increase during the colder months due to seasonal runoff and rainfall, further limiting swimming opportunities.
While the Arkansas River offers a natural setting for swimming, it's often better suited for other water activities like boating, fishing, and kayaking. Swimming is still possible, but it's important to be aware of the river's conditions before entering. For those seeking a warmer and more controlled swimming experience, Fort Smith has public pools and nearby lakes that offer more consistent and comfortable water temperatures year-round.
