Today’s Weather: Thursday, September 7, 2017

The Summary:   Computer Models Say; 15 to 17 mph today. Surf expected to be 4 ft NNW.  We Say;  The actual wind at Kanaha will likely be stronger than the forecast, we estimate that it will be averaging the high teens to mid-twenties. Our “Venturi Factor” Today for Kanaha is 6 out of 10. **Our Gustiness Factor today should be about 40% which is “bumpy” level.  The wind should side-shore and gusty today.  

Shorebreak Warning: Watch out for the King Tides, and the super high tide. Yesterday we had a high tide and big shore-break that was damaging the shoreline and pulling dirt and debris into the water. The water was brown and full of sticks, logs, and other debris, that can hit you or get tangled in your lines. Example: Yesterday I got hit in the leg with a large submerged branch and then it got stuck in my lines as I was exiting the water. I even had to carry the huge branch out of the water with as I exited the water too.

Weather Map: Here is the weather map. The 1021 mb High-pressure system to our north and east, is producing an easterly trade-wind airflow. There is a cold front just to our north that is messing with our trade flow and could bring rain as soon as tomorrow. The front is bending our northern isobar, creating ab even more southeasterly underlying air-flow than yesterday. Wind direction at Kanaha should be “very side-shore” today. Probably expect strong and gusty winds, especially gusty close to shore.
** These predictions are for the generalized (Tradewind) airflow across the state, and local wind effects (rain/venturi/clouds/etc.) need to be considered.

Wind Yesterday:  Here is yesterday’s wind graph. Winds were averaging in the high teens to low 20’s, side onshore. The wind started blowing early and was fairly gusty. The highest gust was about 32 mph late in the day. 

Moon Phase:  Waning Gibbous, Illumination: 98%. The Moon today is in a Waning Gibbous Phase. This is the first phase after the Full Moon occurs. It lasts roughly 7 days with the Moon’s illumination growing smaller each day until the Moon becomes a Lat-Quarter Moon with an illumination of 50%.  More..
Hurricane Season:  Hurricanes are most likely to occur July through December in Hawaii. Hurricanes bring severe bad weather, flooding rain and potentially devastatingly strong winds. The passing of a Hurricane may last days or up to a week or more. The Hurricanes usually develop far away in the eastern Pacific and we generally get several days or more warning of their approach. So there is usually time to make preparations and even evacuate if necessary. Many Hurricanes come close to Hawaii but are just too far away to have a severe effect, This near-miss scenario, and repeated canceled warnings, can give some people a false sense of security. Until one does hit, and then they may be unprepared. Here’s the link to the National Hurricane Center (NHC)

Climate Change Maui: There is a lot of confusion about climate change. There are anthropogenic (man-made) factors that affect climate, like greenhouse gasses, deforestation, and pollution. This is a worldwide problem but has to be managed locally as well. Reducing our carbon footprint using renewable resources like solar and wind energy, as well as recycling and reusing materials rather than throwing materials away after a single use. Also being mindful of not causing harm to the ecosystem by over using toxic agricultural chemicals. Also eating less meat (reduces greenhouse gasses and deforestation) and would be a major step in slowing Global Warming

How climate change affects Maui, we are an island so sea level rise is a problem, There is forecast sea level rise globally with an average of 1.8mm per year. Kahului Maui has a forecast annual sea level rise of 2.1mm per year. which is very small annually by adds up over the longer timescale. Here is an inundation map (below) of Kahului after the 1-meter sea level rise. At current rates, this is estimated to be in approximately 500 years. As you can see Kite beach is still there. The negative effects of climate change should not be underestimated. Severe weather and crop failures will have a dramatic effect on the way we live, Storm damage to property and the relocation and reinforcing of infrastructure will be very disruptive and extremely expensive.

BEACH LOSS: Beach Loss is not solely attributed to sea level rise, it is more directly influenced by man-made problems like destruction of wetlands, destruction of sand stocks, covering shoreline dunes with development, 70 years of sand mining (removal of sand and coral from beaches and nearshore waters), and shoreline hardening. These are things that we can more easily remedy (/ remediate), at least in the short-term. Beach restoration, sand supplementation, Dune stabilization with native plants, sand fencing, limiting overuse of the nearshore zone, and of course shoreline setback regulations for new structures being constructed. Shoreline areas need to be preserved for their vital role in protecting our island from shoreline retreat. Beach loss/sand-loss itself is just the symptom of the underlying problems.

Coral Reef Destruction and Degradation: Coral Reef Protects the shoreline from wave action and allows the build up of sandy beaches. Coral Reefs also provide the raw materials for Coral Sands that most Maui beaches are primarily made of. Healthy Coral needs to be protected and appreciated and valued for its role in coastal protection and beach preservation.

Image from Maui Beach Management Plan. Official estimates for sea level rise (annual 2.1mm) put this “1-meter inundation model scenario” at about 500 years in the future.

To avoid accidents, you should Always Beware of the Shore-Break. Even a small shore break can be very powerful and can turn you upside down, This can lead to serious injury from neck and spinal damage. When entering and exiting with gear the problem is worse. Gear can strike your body or become entangled. a kite can get wrapped around you or pin you under the water, Take extreme care when dealing with a shore-break, if the shorebreak is more than waist-high then you should look for another calmer place to enter and exit. Also do not stay in the impact zone any longer than you need to, get out quickly onto dry sand.

Loss of Beach Access: A most pressing made-made issue is Loss of Beach Access, where less public ocean access is available. This is due to developers, and public planners failing to protect ocean access points. This is the biggest immediate threat the ocean users face here on Maui.  


UPDATE: (We have reached the 1000 signature mark). The Kanaha Parking Petition is Helping Inform Decision Makers and it is already having a positive effect. However, this battle is still not over. We need to keep sharing our stories and giving reasons of WHY Beach Access parking is Important to us. In your comments Please include Some clear reasons of “Which exact parking access (s) you use (each one is evaluated separately), and Why you Need this Parking to remain as is”, and How it would be burdensome if they move existing parking 100 or more meters away from the shoreline. Give reasons and describe things like your activity, the kind of gear you have to take with you etc. What difference would it make to your enjoyment of the sport, your ability to access ocean, and/or would it affect and change your desire to use the area, or perhaps drive you to use another area, causing changes in usage patterns, user density, or create user safety issues?  The more details given in the comments help to paint a clearer picture for the decision makers about How we use these places, and Why they are important to us. They simply do not know the whys. And Please Keep asking your friends to Sign this Petition and ideally make a Comment too. This Petition is still one of the best tools we have to protect our beach.
