The Waimea Bay forecast model shows a large NNW swell arriving on Tuesday, peaking at 13.8 feet at 16.5 seconds. However, the model seems to be running a bit hot at the moment, so be sure to keep an eye on real-time observations from the Northwest Hawaii buoy to see how the swell actually fills in. Winds increase in strength through Wednesday, then maintain a moderate Easterly flow through next Monday.
A long-period Northwest pulse arrives on Sunday (6.2 feet at 17.2 seconds 315°), and is forecast to continue building through Monday. This swell is a bit long-range for the model at the moment, so we recommend checking the forecast in a day or two to see how things develop.
