Manta ray snorkel & box jellyfish

Question

I just learned the next three days are high probability for box jellyfish according to the Waikiki aquarium calendar.

I’m scheduled to do the manta ray snorkel tour near the Mauna Kea hotel. Should I be concerned?

I didn’t bring my wetsuit pants. Should I rent some?

Thanks again for all your help. I’ll do a trip report when we’re home. We’re having a fantastic time.

Answer

It’s great to hear you’re having a fantastic time in Hawaii! When it comes to the box jellyfish warning, it's definitely something to be aware of, but it doesn’t necessarily mean you need to cancel your plans. Here's some important information about box jellyfish and the manta ray snorkel tour:

Box Jellyfish Risk: Box jellyfish are typically found in Hawaiian waters around the full moon, and their presence tends to peak about 3 days after. If you’re seeing a high probability on the Waikiki Aquarium calendar, it’s important to take precautions, especially if you're planning to be in the water. While they are dangerous, the good news is that they are generally concentrated closer to shore, and tour operators are usually aware of their presence and will adjust their routes if necessary.
Snorkel Tour Safety: Most manta ray snorkel tours take you to deeper waters away from the shore, where box jellyfish are less likely to be found. These tours are generally safe, and the tour operators usually monitor jellyfish activity closely. However, it's always a good idea to ask the tour operator directly about the current jellyfish situation before you head out, as they may provide guidance or cancel the tour if necessary.
Wetsuit Pants: Renting wetsuit pants can be a good idea, especially if you are concerned about any potential jellyfish stings. Wetsuit pants offer protection against jellyfish tentacles and can help you feel more comfortable in the water. Even if you’re not worried about jellyfish, a wetsuit will help keep you warm during the snorkel tour, especially in the cooler nighttime waters.

If you’re still unsure, here are a few options:

Check with the Tour Operator: Contact the company running the manta ray tour and ask about their safety measures regarding box jellyfish. They will likely have updated information about the jellyfish conditions and whether wetsuit pants are recommended.
Box Jellyfish Protection: If you’re still concerned about the jellyfish risk, you can always ask the tour operator if they provide any additional protection like long-sleeved wetsuit tops, stinger suits, or vinegar to treat potential stings.

In general, the chance of encountering jellyfish during a manta ray snorkel tour is relatively low, especially since these tours are typically in deeper waters where jellyfish tend to avoid. That being said, it’s always better to be cautious, so renting wetsuit pants is a good precaution, and checking with the operator for updates on jellyfish activity will give you peace of mind.

Enjoy the rest of your trip, and stay safe in the water! Looking forward to reading your trip report when you're back!
