For the River Plate Crossing, there is a strict ban on the use of wetsuits. This rule is implemented for several reasons.
Physical and mental challenge
The neoprene ban increases the challenge of the crossing, testing swimmers' physical and mental endurance. Neoprene provides buoyancy and thermal insulation, making swimming easier. Without it, swimmers must rely solely on their skill and preparation.
Safety and regulations
Wearing wetsuits in warm waters can lead to overheating, which is a significant health risk for swimmers. Body temperature regulation is crucial to avoid heat stroke and other related problems.
Respect for history
The recorded history of over 100 years of crossings has always been without neoprene.
Before each crossing, a detailed study of tide tables and current predictions is carried out. This analysis allows the organisers to choose the best time to start the crossing and plan the most efficient route for the swimmers.
Support vessels equipped with GPS and current monitoring systems play a crucial role in navigation. These vessels guide swimmers towards favorable currents and help them avoid turbulent areas and adverse currents.
Swimmers receive specific training on how to manage currents, including swimming techniques to take advantage of favorable currents and strategies to conserve energy during adverse currents.
The currents of the Río de la Plata play a crucial role in swimming crossings, affecting both the safety and duration of the crossing. To ensure the success and protection of swimmers, it is essential to plan properly, thoroughly understand the prevailing currents, and constantly adapt during the crossing. Nadando Argentina applies these strategies and measures to ensure that each crossing is carried out safely and efficiently for all participants.

The Rio de la Plata has several unique characteristics that significantly affect swim crossings. Currents are one of the most important factors to consider due to their influence on swimmers' safety and crossing time. Below are the predominant currents in the Rio de la Plata and how they affect swim crossings:
Prevailing Currents
1. Tidal Current: The tides in the Rio de la Plata are semidiurnal, meaning that there are two cycles of high and low tide each day. Tidal currents are generated by the difference in water level between high and low tide.
Effect on crossing: These currents can be very strong, especially during the phases of rising tide (ebb tide) and ebb tide (flood tide). Swimmers can benefit from the flow currents pushing them towards their destination, but the ebb currents can make progress difficult.
Effects of currents on daytime crossing
1. Alignment with currents: Crossings are planned with tide times and prevailing currents in mind. Swimmers and organizers can plan the start of the crossing to take advantage of favorable tidal currents, minimizing the effort required and reducing crossing time.
Wind is a critical meteorological factor that can significantly influence the success and safety of crossings.
swimming the Rio de la Plata. Below are the most important aspects related to wind and weather conditions, and how these affect the planning and execution of crossings.
Forecasting and monitoring
Crossing planning is based on detailed weather forecasts including wind speed and direction, as well as other weather conditions such as rainfall and temperature.
Effect on crossing: Organizers continuously monitor weather conditions before and during the crossing to make informed decisions about start time and necessary safety measures.
Choosing the time to cross the Río de la Plata is a process that requires careful consideration of several key factors to ensure the safety and success of the journey. Below are the main aspects that are taken into account:
Swimmer speed by regulation
Swimmer Speed Assessment: Prior to the crossing, each swimmer's average speed in open water conditions is assessed. This is crucial to estimate the time it will take them to complete the crossing.
Tide coefficients and times
Tide Study: A detailed analysis of tide coefficients and times is carried out for the day of the crossing. Tides significantly influence river currents, and proper planning can help take advantage of favourable currents.
Tidal synchronization: The start of the crossing is synchronized with the tides to maximize the use of favorable currents and minimize resistance from countercurrents. For example, the crossing can be timed to begin with the rising tide if it is pushing in the desired direction.
Wind forecast for the day of the crossing
Selecting the optimal time: the starting time is chosen based on wind forecasts, looking for periods of relative calm or favourable winds. Starting the crossing during strong or increasing winds is avoided.
Procedure for choosing the time
1. Review of weather and ocean data: days before the crossing, weather forecasts and tide tables are reviewed. Up-to-date information is obtained on wind speed and direction, as well as tidal coefficients.
2. Coordination with maritime authorities: Coordination is carried out with the maritime authorities of Argentina and Uruguay to obtain authorizations and ensure that there are no conflicts with ship traffic. The authorities provide additional information on river conditions and possible restrictions.
3. Final decision: The final decision on the start time of the crossing is made considering all the above factors.
The start time is communicated to all participants and support teams, along with specific instructions on safety procedures and monitoring of real-time weather conditions.
Choosing the right time to cross the Rio de la Plata is a complex process that involves assessing swimmers’ speed, tide coefficients and times, and wind predictions. Each of these factors is essential to ensure a safe and successful crossing. Coordination with authorities and the use of accurate and up-to-date data allows for optimizing the starting time, ensuring that swimmers can face the best possible conditions during their journey.
Nadando Argentina offers three types of crossings across the Río de la Plata, each with unique characteristics and a focus on safety and respect for the history of the crossing. All types of crossings are carried out without the use of wetsuits, maintaining the tradition and authenticity of the challenge.
