DISCUSSION
SMALL SURF FOR NORTH FACING SHORES IS EXPECTED THROUGH TOMORROW
BEFORE A SMALL NORTHWEST SWELL ARRIVES GIVING A SMALL BUMP
THURSDAY AFTERNOON AND FRIDAY. THIS WILL THEN BE FOLLOWED BY A
SLIGHTLY LARGER MID PERIOD NORTH- NORTHWEST SWELL THIS WEEKEND. A
POTENTIAL STORM FORCE LOW IN THE PROCESS OF DEVELOPING NORTH OF
JAPAN COULD SEND A LARGER LONG PERIOD WEST- NORTHWEST SWELL EARLY
NEXT WEEK. THIS SWELL IS STILL UNCERTAIN AND WILL DEPEND ON THE
EVOLUTION OF THE DEVELOPING LOW.
SMALL BACKGROUND SOUTH SWELLS WILL KEEP RELATIVELY SMALL SURF FOR
SOUTH FACING SHORES THROUGH MUCH OF THE WEEK. A MODERATE SOUTH-
SOUTHWEST SWELL IS EXPECTED THIS WEEKEND, AND COULD BRING SURF
HEIGHTS ABOVE SEASONAL AVERAGES.
ROUGH TRADE WIND SWELL WILL GRADUALLY DECLINE LATER TOMORROW
MORNING AS TRADE WINDS DECREASE, LEADING TO SMALLER SURF THROUGH
THE REMAINDER OF THE WEEK. A SMALL MEDIUM PERIOD EAST SWELL IS
POSSIBLE THURSDAY INTO THE WEEKEND.
