Water safety tips
- Enter Veluwemeer slowly and let your breathing settle before swimming out — cold shock is the biggest single risk in fresh water.
- Swim parallel to the shore rather than out and back, so you are never far from a safe exit.
- Lakes have no lifeguard on most shorelines: swim with a partner and use a bright tow float so boats can see you.
- Check for boat traffic, sudden drop-offs, weed beds and submerged obstacles before your first swim of the season.
- Deep lakes stay cold below the surface even in a heatwave — expect a sharp thermocline a metre or two down.
- After heavy rain or during a warm calm spell, avoid swallowing water: runoff and algal blooms can cause illness.
- Get warm and dressed quickly after cold swims — afterdrop peaks 10–30 minutes out of the water.
