Weather Map: Here is the weather map (The Map didn’t update from yesterday on the NWS site, so we didn’t update our summary of it). The 1019 mb High-pressure system to our east-northeast is producing a weakening trade-wind airflow. There is a remnant cold front to our north and another large cold front approaching from the north west, they are messing with our trade winds. The circularity of our northern upwind isobar suggests a more southeasterly underlying air flow today. Wind direction at Kanaha should be “variable onshore” today. It could be cloudy especially towards the interior of the island, and hazy (voggy).
** 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 lighter with a very side-onshore direction. The wind started blowing early. Winds averaged mid teens, gusting high teens. The highest gust was about 22 mph. 

Moon Phase:  Waxing Gibbous, Illumination: 99%. The Moon today is in a Waxing Gibbous phase. This phase is when the moon is more than 50% illuminated but not yet a Full Moon. The phase lasts around 7 days with the moon becoming more illuminated each day until the Full Moon.  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 the affect climate, like greenhouse gasses, and 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 overusing toxic agricultural chemicals, Also eating less meat would be some major steps in reducing greenhouse gasses and 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 will could be in about 50 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, 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.


If in doubt, don't go out.

To avoid accidents on the Beach and on the Water, you should Not go out if you are in Doubt. If you are unsure of the conditions, or unsure of your abilities, or unsure of your equipment, then do not go out. You should only launch of you have confidence that you can manage the conditions and remain safe during the activity, If you are unsure of the conditions ask an instructor to assist you or advise you. Self Doubt is usually a sign that the conditions are not right or that you should get some more training. And/or buy the correct kite size. If you did go out anyway, you may get yourself into a bad situation, and then put other people in danger too.

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.
