Dive Site Characteristics
Dive Site Overview
Wythmenerplas offers a clear and structured dive environment, primarily accessed as a shore dive. Entry is easy thanks to gently sloping points, accommodating divers of all mobility levels.
Descending, divers encounter a soft, sandy bottom, characteristic of this aquatic environment, reaching a maximum depth of 18 m (59 ft). Within these depths, a comprehensive line system guides exploration, leading from the main jetty to a significant car wreck situated around the 5-meter mark. Continuing along the line, divers find another 5-meter platform, located at a separate entry point.
This established system simplifies navigation, proving particularly beneficial for training purposes and low visibility conditions. Beyond the main features, other underwater objects, while not consistently reported, provide additional exploration possibilities, enhancing the overall dive experience.
For night diving, the site functions well, offering a different perspective on its familiar layout and structures. Above the surface, recreational activities like camping and various water sports are common during summer months.
Best Time to Dive
Planning dives at Wythmenerplas often hinges on maximizing visibility, which typically ranges from 3 to 6 meters (10 to 20 ft), with an average of around 3 meters. The warmer months from May through September generally offer the most comfortable conditions for diving. During this period, average air temperatures range from 14-18°C (57-64°F), contributing to a more pleasant topside experience and potentially warmer surface water. While rain occurs throughout the year, May and August show lower average rainfall, which can sometimes correlate with improved underwater clarity. Conversely, colder air temperatures from October to April, ranging from 2.5-12°C (36-54°F), make drysuit diving almost essential here. September and August often receive higher dive scores, suggesting good overall conditions, including better visibility and more agreeable surface weather, making them prime months for underwater exploration.

Dive Experience & Conditions
Diving within this inland water body involves generally calm conditions; strong currents are not typically reported. Visibility varies depending on recent weather and seasonal factors, but divers can usually expect a range of 3 to 6 meters, with an average of about 3 meters. Water temperatures fluctuate significantly throughout the year; log reports suggest temperatures can span from below freezing in winter to around 18-20°C (64-68°F) in summer at shallower depths, though consistent specific water temperature data is limited.

A gently sloping bottom, composed of sand and sediment, characterizes much of the site, making entries and exits relatively easy for all diver types. This consistent bottom contour and the absence of strong currents create a predictable and generally relaxing dive experience.
