Surf Forecast - Hawaii
5 Day Surf Forecast

Forecast Updated:
Tuesday, March 16, 2010 8:11 PM GMT

Surf Scale: 3 ft = waist high, 4 ft = chest high, 5 ft = head high, 10 ft =double overhead
Swell Direction is direction swell is coming from. 90°=East, 180°=South, 270°=West, 360-0 = North

NOTE: Forecast does NOT account for enhancing bathymetry (i.e the 'reef effect') common at best breaks. For top spots with swell period 14 +secs, multiply surf size X 1.25-1.5 with peaks X 2 (or consider the stated size 'Hawaiian Scale').

Hawaiian North Shore Surf Forecast (Valid for the North and East Shores of Oahu)
Day	Trend	Wind (kts)	Details (Swell Number, Swell Size & Period, Arrival Time and Profile)	Waves (Set wave max face height)	Swell Direction
Wednesday 3/17	Down some	N 5 later	Gulf swell fading from 7.8 ft @ 12 secs early	9.0 ft	340-350 degrees
Thursday 3/18	Down	NNE 20	Swell 4.5 ft @ 11-12 secs	5.5 ft	350 degrees
Friday 3/19	Up some	NE 15+	Possible new local Gulf swell to 8 ft @ 13 secs	10-11 ft	330 degrees
Saturday 3/20	Down some	NE 15+	Local swell fading from 7.0 ft @ 11-12 secs	8.0 ft	330 degrees
Sunday 3/21	Down some	ENE 15+	Background swell 4 ft @ 15 secs	6.0 ft	320 degrees
Extended Outlook	Up some	---	The Madden Julian Oscillation (MJO) is in the Inactive state and expected to continue there through early next month. No direct support for gale development expected from it but El Nino will continue to favor gale and storm formation for a few more months (including in the Southern Hemi). A weaker system is forecast forming just north of the Islands Wed/Thurs (3/18) with 23 ft seas. Maybe some raw local windswell to result for Fri (3/19) and beyond. A solid gale is modeled on the dateline over the coming weekend (3/20) with 37 ft seas, but that is pure fantasy at this early date.	---	---

Extended Outlook	Down slow	---	Down south a weak/small gale formed southeast of Tahiti Thurs (3/11) with barely 30 ft seas. Small swell likely is radiating north for Tues-Thurs (3/18). A stronger storm formed just southeast of New Zealand Sat/Sun (3/14) with 50 kt winds and seas modeled up to 46 ft, though 40 ft was only confirmed. Regardless, real southern hemi swell expected by the weekend and beyond.	---	---
