Hurricane Season in Hawaii

June 1st through November 30th

Be Prepared!

Hurricane Iniki, September 11, 1992

Develop a family disaster preparedness plan now. Determine evacuation routes from your home and places to meet. Determine the location of official shelters. Have an out of state contact, so all your family members have a single point of contact.

Make a plan for what to do with your pets if you need to evacuate. Check your insurance coverage; flood damage is not usually covered by homeowners insurance.

See WSC's Hawaii Weather page for tropical weather forecast.

The state Supreme Court has ordered a stop to the commercial collection of aquarium fish in Hawaii pending an environmental review.

In a unanimous 73-page decision Wednesday, the justices ruled against the Department of Land and Natural Resources, vacating prior court rulings and directing the Circuit Court to issue a prohibitory injunction.

The court found that the commercial collection of fish for the aquarium trade is an “action” that is subject to the state environmental review process as laid out under the Hawaii Environmental Policy Act.

Hawaii Governor Vetoes Aquarium Fishing Bill

Gov. David Ige faced a heavy lobbying campaign from both sides on a bill phasing out commercial collection of fish for the aquarium industry.

From Civil Beat, by Nathan Eagle July 11, 2017

Gov. David Ige announced Tuesday that he has decided to veto a bill that would have phased out the commercial collection of aquarium fish in Hawaii.

The governor said he will also veto 12 other bills, including a measure that would have required the state Attorney General’s office to defend lifeguards in liability lawsuits since the Legislature let their immunity protection expire June 30.

House and Senate leaders announced Monday that the Legislature will not convene a special session to override any vetoed bills. They said they would review the governor’s concerns with any vetoed measures and consider them during the next regular session, which starts in January.

1st day of influx is usually on the 8th or 9th day after the full moon, lasting 2 or 3 days. Exact arrival timing and magnitude vary month to month.

DLNR Asks Ocean Users to Avoid Sunscreens with Oxybenzone

A compound commonly found in sunscreens has been shown to cause serious harm to corals, and the Department of Land and Natural Resources (DLNR) is asking people who enter the ocean to avoid using sunscreens which contain oxybenzone.

A recent study has shown that oxybenzone causes deformities in coral larvae (planulae), making them unable to swim, settle out, and form new coral colonies. It also increases the rate at which coral bleaching occurs. This puts coral reef health at risk, and reduces resiliency to climate change.

Sunscreen chemicals wash off swimmers, surfers, paddlers, spearfishers, divers, and other ocean users. Even if you’re just sunbathing on the beach, using beach showers will wash chemicals into the ocean. Researchers have found oxybenzone concentrations in some Hawaiian waters at more than 30 times the level considered safe for corals.
