SEA SURFACE TEMPERATURE
Our sea temperatures have a fluctuating
range of plus or minus 5 degrees F or 2 degrees C. This is because the water temperatures below the surface are usually colder
than the surface. In our area the average temperature at 17 fathoms (100 feet or 30 metres) for this time of year is about
34.9oF (1.6oC). However, with our large tidal range and frequent periods of high wind
waves, the surface water will be mixed with the colder water below, therefore from time to time lowering the surface temperature
to almost the same water temperature as at 100 feet.

temperature as taken from the west wharf in Clark's Harbour on or around the dates shown.
