Hi Saul and Walt,
Walt and Nick are certainly far more experienced at TP-DXing than me,  and
Walt's ocean beach Haida Gwaii (BC) DXpedition site is phenomenal in
comparison to my mediocre (Puyallup, WA) location. But maybe a 
few  comments from
the perspective of an Ultralight radio TP-chaser might be  interesting.
Depending upon the solar conditions, Asiatic TP signals generally  hit
their peak here from September through mid-November, although this  year both
the strength and duration of the peak TP season was seriously  down from last
year. Guy Atkins and I both live in an inland location about 100  air miles
from the ocean, so we don't enjoy the salt water  propagation that Walt,
Nick and Colin experience in Victoria.
