Ocean Safety in Maui

The ocean is a key draw to any Maui vacation! It's also a powerful force that can change conditions in a matter of minutes. To ensure you and your family enjoy a safe visit to Maui's beaches, we recommend adhering to the following practices:

  • Never Turn Your Back on the Ocean - Always be aware of what the water is doing.
  • If In Doubt, Don't Go Out - It's always better to play it safe and avoid the water if you aren't fully sure how safe conditions will be.
  • Follow Safety Signage & Lifeguard Instructions - Swim at beaches with lifeguards to help keep you safe in the event of rogue waves, brown water, or strong tides. 
  • Use the Buddy System - Always take a friend. Whether you're snorkeling or swimming, having a buddy is an easy way to stay safe in the water.

Leave No Trace Principles

Leave No Trace is a set of principles designed to promote conservation in the outdoors. It's about making good decisions to protect the world around us and keeping our natural spaces beautiful and accessible for generations to come. When visiting Maui, it's essential to adhere to these principles.

By following the Leave No Trace principles, you're not just a visitor, but a caretaker of Maui's stunning natural beauty, helping to preserve its charm and biodiversity for the future.

Simple actions like staying on marked trails, picking up trash, and respecting local wildlife can help protect Maui and its ecosystem for future visitors and its residents.

  • Plan and Be Prepared - Know the routes you plan on traveling along with local restrictions, weather, and any updates that may affect your day out in nature.
  • Stay On Designated Trails - Hike single file and do not make your own path. Respect the environment by staying on designated trails and not altering them in any fashion.
  • Pack It In, Pack It Out - Properly dispose of any trash or waste that you create during your time on Maui. Use marked restroom locations and do not wander off-trail.
  • Leave What You Find - No matter how beautiful a seashell you find on the beach, it is best to leave the natural environment as you find it. Leave everything you find during your Maui adventures undisturbed and do not introduce or travel with any species non-native to the island.
  • Respect Wildlife and Others - Do not approach, feed, or follow wildlife. If driving, be mindful of speed limits and any wildlife you may encounter. Minimize your impact on the environment by avoiding popular visiting hours and limiting the noise you produce.

Coral Reef Preservation and Protection

Hawaii has banned the sale of sunscreen that contains harmful chemicals (octinoxate and oxybenzone). These chemicals cause coral bleaching, which puts reefs under stress and may lead to reef mortality.

With an estimated 14,000 tons of sunscreen introduced to coral reefs each year, it is essential that visitors be mindful of their impact and do their part to minimize it.

Although these harmful sunscreens can no longer be purchased on the island, make sure that your sunscreen does not include harmful ingredients before you enter the ocean.

Humpback Whale Watching in Maui

If humpback whale watching is a top priority for your Maui itinerary, book your travel from November through April. Visitors can view whales breaching from the ocean or even go out on a whale-watching excursion with a local company.

This is one of Maui’s most popular experiences, so it’s a good idea to plan well in advance. Staying near the coast can also make it easier to spot whales early in the morning throughout your trip.

Best Time to Visit Maui

Maui’s high season typically falls between November and March. During this time of year, you can expect the highest rates and largest crowds. If you're planning to visit Maui during peak season, book your stay early. If you plan to rent a car, you should also book well in advance, as availability can be limited.

The off-season is typically fall and spring break, with lower fares and fewer crowds. Take your pick of accommodations and benefit from a quieter time on the island.

Plus, the island’s rainy season is typically during the winter months, so visitors in the spring and fall will likely enjoy sunnier weather. When you are ready to plan your trip, check out our Maui Area Guide to help find the best attractions and sights on the island!
