Swell Summary
Recent satellite ASCAT wind observations verify a large region of strong trades upstream of the state that will generate a long fetch region and push in an easterly swell. Strong trade winds will also build large wind-driven easterly seas. Both east wind waves and swells will translate to rough sea conditions and higher east-facing shoreline surf. Surf heights along eastern-facing shores will exceed surf advisory levels today. Thus, a High Surf Advisory (HSA) is in effect for the remainder of the week to account for persistent strong trades keeping surf elevated along most eastern exposures.
A couple of small, overlapping relatively longer period west to northwest swells will travel around the islands the next few days. The first of these swells will be arriving later today and level out through Tuesday afternoon. The second set of similar low west to northwest swells will be moving through during mid to late week. Surf along north and west-facing shores will remain well below HSA levels through Friday. Surf along south-facing shores will remain small into the weekend. A small bump in southern swell arriving later in the week will provide a slight increase to south-facing shoreline surf by Friday.
NORTH EAST
am pm
Surf: Waist to chest high E short period wind swell.
Conditions: Sideshore texture/chop with SSE winds 15-20mph in the morning shifting SE for the afternoon.
NORTH WEST
am pm
Surf: Minimal (ankle high or less) surf.
Conditions: Glassy in the early morning with SW winds less than 5mph. Bumpy/semi bumpy conditions move in during the morning hours with the winds shifting W 5-10mph.
WEST
am pm
Surf: Minimal (ankle high or less) surf.
Conditions: Glassy in the morning with ESE winds less than 5mph. Bumpy/semi bumpy conditions for the afternoon with the winds shifting WNW 5-10mph.
SOUTH EAST
am pm
Surf: Knee to waist high E short period wind swell for the morning with occasional stomach sets. This builds to waist to chest high for the afternoon.
Conditions: Fairly clean in the early morning with N winds 5-10mph. Sideshore texture/chop conditions move in during the morning hours with the winds shifting NE.
