Water Sports with the Class: Risk Assessment Based on Wind and Weather Forecasts

Activities like canoeing, sailing, or stand-up paddling are popular on class trips. However, on the water, you are directly exposed to the weather. A careful risk assessment is essential for teachers.

1. Wind: The Decisive Factor

Wind is the biggest danger in most water sports.

• Canoe/Kayak/SUP: Starting from wind force 4 (approx. 20-28 km/h), it becomes very strenuous and dangerous for beginners. Offshore wind can drive boats out into open water. Always plan tours so that you paddle against the wind first.
• Sailing: Here, wind is desired, but too much is dangerous. The upper limits depend on the boat type and the students' experience. Set clear limits in advance (e.g., "No departure with gusts over wind force 5").

2. Thunderstorms: The Deadly Danger

Water attracts lightning. At the slightest thunderstorm warning or with approaching storm clouds, the rule is:

• Get off the water IMMEDIATELY. No room for discussion.
• Seek shelter in solid buildings, not under trees on the shore.
• Check the rain radar before and during the tour.

3. Water Temperature: The Invisible Danger

Even in summer, German lakes and the North/Baltic Sea can be very cold. A fall into cold water can quickly lead to cold shock and hypothermia.

• Find out the current water temperature.
• For water temperatures below 18°C (64°F), wetsuits are strongly recommended for activities like SUP, where falling in is likely.
• All students must wear a suitable life jacket, regardless of their swimming ability.

4. Sun and UV Radiation

On the water, UV radiation is particularly intense due to reflection. Insist on waterproof sunscreen, head coverings, and sunglasses. Plan for breaks in the shade.
