Wind and fog are additional factors to consider when planning a trip and out on the water.

Winds generally blow from the west or northwest in the summer and are greatest during the afternoon, making mornings the best time to paddle. In the winter southwest winds tend to bring rain, and easterly, down-Gorge winds bring cold air. Topography and differences in temperature and air pressure can also create strong, localized winds.

Fog is extremely disorienting. Familiarity with the area or strong compass skills are necessary to navigate in these conditions. Leave room for error. Do not aim for small waypoints, such as a small island or the end of a peninsula. Shoot for large targets, and once you have reached them, proceed along them safely to your next destination. Do not cross shipping channels in the fog.

Finally, remain flexible and do not be a slave to your schedule. This will only cause you to make rash decisions and take chances. Plus, going with the flow allows you to enjoy the river more. Happy paddling.
