West Swell (270 Degrees) = Heading East. Swells are waves not produced by the local wind and come in at a higher period (longer wave length) than waves produced by the local wind. Depending on how low the low-pressure is and what direction it has, related to where your surf break is, together with wind speed. So back to a MSW forecast – you can see the swell direction arrows (ringed red in this example). Wave Direction / Swell Direction. A collection of ocean swells moves in a general direction, but does not move in the exact same heading. Knowing which direction the swell or waves are coming from will give you an idea of how the wave will be hitting your area. Swells are re-directed by shallow spots on the ocean floor. Wavelength. Swell direction is the direction the swell is coming from, as opposed to the direction it is heading toward. MM or … Wind: Large area of 30-40 knot wind with pockets to 50 knots. These arrows point in the direction the swell is heading TO, in this case TO the South East – so the swell is coming FROM the North West or 315 degrees so we call it a North West swell. Swell Direction (SwD) This is the direction that the swells are coming from. Storm Movement and Direction: Nearly stationary Tasman low rapidly strengthened July 13th-14th before slowly tracking east. Swell refers to waves that develop over a longer period of time than locally-generated wind waves, and over a larger area. The differences creates a swell and that is a stronger wave that comes out from that. the distance between two peaks) Whitewater Swell Travel Time: Half-one day initially, then 1-2 days as the storm moved to the east. The waves will usually be heading in the opposite direction to any aircraft on final approach, since it will be landing into wind. You need to take in the landscapes, hills, and cliffs that surround a spot – they can provide great shelter from the wind. If you stand so that the wind is blowing directly into your face, the direction you are facing names the wind. Swell Signature. Wind direction is defined as the direction the wind is coming from. These pictures were taken from the right hand (starboard) side of an aircraft on final approach to the airport. In each case the waves are moving broadly from left to right and the swell is moving from bottom to top. The AUSWAVE model outputs a primary and secondary swell to refer to the height and direction of the swell with the highest (and second highest) energy component. The final aspect of swell we need to cover is the swell’s period. Primary Swell Direction Secondery Swell Height (0 - 20 ft) Secondery Swell Period (0 - 40s) Secondery Swell Direction Wind Speed (0 - 30 mph) Wind Direction Weather. This is the distance between two corresponding points on successive waves. Kahaluu Bay, located here in Kona, Hawaii is a West facing reef break.It receives waves from just about any direction which makes it a great surfing spot all year round. The direction a spot faces isn’t all you need to know either. It is really obvious when you follow up how waves appears in a limited sea like the Baltic sea. Marie Swell Period and Direction. Seas: Modelled to reach 30’ just offshore of Sydney. (Not the direction in which they are heading) If a surf spot works on a northerly, this refers to a northerly swell direction. Direction is given on a 16 point compass scale. The period is a measure of time between individual waves and is expressed in seconds. Swell. This is the direction from where the waves approach. ...
