Swell Summary
An extra large, long period northwest (310-320 degree) swell is quickly filling in around the islands this morning. Swell observations at the northwest offshore buoys rapidly shot up to 25 feet or greater this morning. This XL swell will produce dangerous giant size surf along many north and west-facing shores through Monday afternoon. A High Surf Warning (HSW) is in effect through Monday afternoon for many north and west-facing shores. There will be adverse impacts to coastal properties, harbors and infrastructure, including coastal roadways impacted by overwash, today and Monday, especially during periods of high tide. A westerly component to the swell has increased the potential for elevated surf along the western shores of Maui and Lanai. A High Surf Advisory (HSA) is in effect for these shores. The swell will gradually subside through Monday but will then be followed by large northwest (310-330 degree) swell that is timed to arrive at mid week. This swell will likely lift surf back up to HSW levels Wednesday. Surf along south-facing shores will remain small but, due to the more westerly component the swell, select areas could experience increased surf in response to a westerly wrap. Short period, choppy wave conditions along eastern shores will be associated with persistent moderate east trades through at least Tuesday.
