Kayaking is an outdoor sport, and requires physical exertion. You will be exposed to sun, wind, rain, waves, etc. sometimes all at once. As such, there are inherent risks:
You will get wet from splashing paddles, waves, or rain.
Tides, wind, and waves may make navigation difficult so check the weather both before launch time and during your trip.
Various hazards exist in the water, including oyster beds and wildlife. All are easy to avoid if you pay attention.
Mud flats can be difficult to navigate on foot. Should you decide to step out of your kayak, check the firmness of the bottom with your paddle first.
