Advection Fog
Fog is one of the major hazards which faces sea kayakers and yesterday from the north coast of Jersey there was a classic example of the formation of fog over the cold sea surface.
With an air temperature of 21 ° C, a water temperature of 10 °C and almost no wind conditions were ideal for the formation of fog. To the north the higher parts of the island of Sark were rising above the fog.
The Paternosters, about 3 miles to the north of Jersey were clear but beyond that visibility dropped significantly creating far more challenging conditions for any paddlers in the area.
Paddling early in the season when there is a large difference between air and water temperatures can bring additional hazards to sea kayaking and it is one feature of the weather which we need to be aware of.
