DISCUSSION
A SMALL, MEDIUM-PERIOD, NORTHWEST SWELL BUILD TODAY, PROVIDING A SMALL
BUMP TO SURF ALONG NORTH AND WEST-FACING SHORES. AT LEAST ONE OTHER
NORTHWEST SWELL OF SIMILAR SIZE AND PERIOD ARRIVES LATE TODAY WHICH
WILL SUPPORT ELEVATED SURF ALONG WEST-FACING SHORES THROUGH MID-WEEK.
A MODERATE, MEDIUM-PERIOD NORTH-NORTHEAST SWELL ALSO ARRIVES TODAY
AND PEAKS ON WEDNESDAY, BRINGING MODERATE SURF TO NORTH-FACING
SHORES, BEFORE SLOWLY DECLINING THROUGH THE END OF THE WEEK. EAST-
FACING SHORES WILL SEE AN INCREASE IN SURF WITH WRAP FROM THE
NORTH-NORTHEASTERLY SWELL, DESPITE BELOW SEASONAL AVERAGE TRADE
WINDS. STRENGTHENING TRADES LATE THIS WEEK WILL SUPPORT CLOSER TO
SEASONAL AVERAGE SURF FOR EAST FACING SHORES INTO THE WEEKEND.
SURF WILL CONTINUE TO BE SMALL ALONG SOUTH FACING SHORES THROUGH
THE PERIOD.
