Swell Summary
A 2 to 3 foot south swell appears to be lingering at the nearshore buoys in the 13-15 second range. As a result, south shore surf will likely remain slightly elevated through tonight, before gradually declining Monday. The next small, long-period south swell is expected to arrive Tuesday and peak Wednesday night into Thursday. This swell will produce another small boost in surf along south facing shores before declining through the rest of the week.
A tiny pulse from the north-northwest will fade today with nearly flat conditions returning Monday and Tuesday. Another small north- northwest pulse is possible Wednesday through the second half of the week, producing tiny surf along north facing shores.
Near shore buoys are showing an uptick in 8-10 second period energy out of the east overnight. This uptick is partly due to trades increasing both upstream and locally and possibly from small pulses of east swell from former Tropical Cyclone Emilia. Choppy east shore surf can be expected through much of the week as trades persist.
