Pärnu River Mouth Beach is generally considered safe for swimming, but it's important to be aware that it's located at the mouth of a river. While the main bayfront area is typically calm, conditions can vary slightly closer to the river channel due to currents. It's always advisable to observe local signage and conditions. During peak season, lifeguards may be present, but caution is recommended, especially for less experienced swimmers.

For good weather and fewer crowds, the best time to visit Pärnu River Mouth Beach is often during the shoulder seasons, such as late spring (May-early June) or early autumn (September). While summer (July-August) offers the warmest temperatures, it also attracts more visitors. Visiting outside peak summer allows you to enjoy the scenic beauty and tranquility of this 'hidden' urban spot with more space and potentially milder temperatures.

Pärnu River Mouth Beach is an urban beach, meaning it's relatively accessible within Pärnu. While it might be a bit further from the absolute city center compared to the main promenade, it can typically be reached by walking or cycling. Public transport options, such as local buses, likely have stops within a reasonable distance. For those driving, some parking may be available in the vicinity, though it might be less formal than at the main resort areas.

As a more 'hidden' and less developed beach area compared to the central resort, Pärnu River Mouth Beach may have limited direct food and lodging options. It's advisable to plan to bring your own snacks and drinks, especially if you intend to spend a longer period there. However, being an urban beach, the main city center with its restaurants, cafes, and hotels is usually just a short walk or drive away, offering plenty of choices.

Pärnu River Mouth Beach is unique because of its distinctive location, separating Pärnu's bayfront from its harbor and river landscape. This offers picturesque and dynamic views, including glimpses of boats, the river, and the open bay. It provides a more tranquil and scenic experience compared to the bustling central promenade, making it ideal for those seeking a peaceful escape, photography opportunities, and a different perspective of Pärnu's coastal environment.
