HONOLULU SURF FILM FEST 2019

645am Obs Sunday July 21st

Another beautiful morning with light ENE trades increasing to moderate (10-20mph). A few passing clouds but mostly clear for Leeward & broken clouds for Windward/ Mauka. Small craft advisory for channels East of Moloka'i.

Tiny remnant SSW & easing background ENE trade wind energy. Call 596-SURF: 7a, noon, 3 & 5 (recap-forecast).

North Shore:

Down and dropping tiny NE trade wind wrap. Flat-inches for top spots with light side-off early filling to moderate pace. A great day for fishing, paddling, diving... Sunset Pt. mostly flat like most reefs. Chuns maybe occ. 1' NNW. Laniakea up to 1' but poor shape. Haleiwa flat all under broken clouds.
Untitled-1

West:

Down and dropping remnant SSW. Makaha is flat to occ. 1' and smooth offshore but lacking both size & energy. Great day for most other beach activities under mostly clear skies.
Untitled-1

Town:

Down & Dropping small 8sec SSW. Surf is fairly clean 1-2' and will continue it's decline through the day. Weak and inconsistent with some lingering waist-high sets for top reefs from Kewalos to Courts, Bowls to Kaisers; Canoes-Queens are mostly 1-2' sets under plenty of blue.

Diamond Head:

Down & dropping the tiny SSW. Surfs 1-2' occ.+ still showing a little pulse for top reef sections. Light-moderate side-off with small, crumbly whitewater sections rolling through the lineup under passing clouds.

Sandy's:

Down and dropping the mix of small SSW and easing ENE wind swell. Surf is bumpy 1-2' occ.+ and fair with peaky, inconsistent energy: Middle Peaks-Cobbles to Gas Chambers providing playful closeout sections under clouds.

East Makapu'u:

Down and dropping small 8sec wind swell. Makapu'u is choppy onshore 1-2'+ and fair overall with small inside closeouts providing fun inside mini-ramp sections; all under clouds.

Get the latest on the tropics at www.hurricanes.gov
The Central Pacific Hurricane Center outlook for the 2017 Central Pacific Hurricane Season calls for 5 to 8 tropical cyclones to either develop or cross into the Central Pacific with a 40% chance for an above-normal season, a 40% chance for a normal season, and a 20% chance for a below-normal season. An average season has 4 to 5 tropical cyclones, which include tropical depressions, tropical storms, and hurricanes.
A tropical depression forms when a low-pressure area is accompanied by thunderstorms that produce a circular wind flow with maximum sustained winds below 39 mph. An upgrade to a tropical storm occurs when cyclonic circulation becomes more organized and maximum sustained winds gust between 39 mph and 73 mph. A tropical storm is then upgraded into Category 1 hurricane status as maximum sustained winds increase to between 74 mph and 95 mph. (The highest classification in the scale, Category 5, is reserved for storms with winds exceeding 156 mph).
Tropical cyclones go by many names around the world, and the terminology can get confusing. Once a tropical cyclone strengthens to the point where it has gale-force winds—39 mph or greater—it becomes a tropical storm. A storm that reaches tropical storm strength usually gets its own name to help us quickly identify it in forecasts and warnings. Once a tropical storm begins producing sustained winds of around 75 mph, we call the storm a typhoon in the western Pacific near Asia and a hurricane in the oceans on either side of North America. A “typhoon” and a “hurricane” are the same kind of storm, they just go by different names…it’s only a matter of geography.
NWS criteria for High Surf Advisories & Warnings.
In coordination with civil defense agencies & water safety organizations in Hawai`i, the NWS uses the criteria below for the issuance of High Surf Advisories & Warnings in coordination with civil defense agencies & water safety organizations in Hawai`i.
All surf height observations & forecasts are for the full face surf height, from the trough to the crest of the wave.

ENSO is a single climate phenomenon, it has three states or phases. The two opposite phases, “El Niño” and “La Niña,” require certain changes in both the ocean and the atmosphere because ENSO is a coupled climate phenomenon. “Neutral” is in the middle of the continuum. The MJO (Madden-Julian Oscillation) is an eastward moving disturbance of clouds, rainfall, winds, and pressure that traverses the planet in the tropics and returns to its initial starting point in 30 to 60 days, on average, unlike ENSO which is stationary. In a nutshell, more active means more surf.
Kelvin wave (A Kelvin wave is a wave in the ocean or atmosphere that balances the Earth's Coriolis force against a topographic boundary such as a coastline, or a waveguide such as the equator. A feature of a Kelvin wave is that it is non-dispersive, i.e., the phase speed of the wave crests is equal to the group speed of the wave energy for all frequencies. This means that it retains its shape as it moves in the alongshore direction over time.)
