South Maui Beach Closures Threaten 72-Hour Revenue Loss for Coastal Businesses
Wider Beach Advisories Could Impact Maui's Core Tourism Season
Maui's tourism operators and coastal small businesses face immediate revenue disruption due to a Brown Water Advisory issued for Kamaʻole II in South Maui, effective January 14, 2026. The advisory, triggered by rainfall and consequent runoff, recommends avoiding water entry for 48-72 hours after the cessation of rain and the return of full sunshine. This advisory effectively closes the beach to recreational activities that form the bedrock of many local businesses' operations.
The Change
On January 14, 2026, the Department of Health issued a Brown Water Advisory for Kamaʻole II beach in South Maui. This advisory is a public health recommendation advising against swimming, surfing, and other water activities due to potential contamination from runoff. The advisory typically remains in effect for 48 to 72 hours following the rainfall, contingent on the beach receiving full sunshine. While specific to Kamaʻole II, similar advisories can affect multiple popular South Maui beaches after significant rainfall events, impacting a larger swathe of the visitor experience.
Who's Affected
-
Tourism Operators (Hotels, Tour Companies, Vacation Rentals): This advisory directly impacts businesses that offer or rely on beach and ocean activities. Ocean-based tours, such as snorkeling, diving, and surf lessons, will likely face cancellations or postponements. Hotels that promote beach access and local activities may experience guest dissatisfaction and direct booking losses for the duration of the advisory. Vacation rental hosts in the vicinity of Kamaʻole II might see a dip in immediate bookings or increased guest complaints if beach access is implicitly or explicitly part of their offering.
-
Small Business Operators (Restaurants, Retail, Service Providers): Businesses with a primary customer base of beachgoers will experience a significant drop in foot traffic and sales. Restaurants and cafes located near Kamaʻole II will likely see reduced patronage. Retail shops selling beach gear, souvenirs, or essentials will also be affected. While the advisory is specific to water entry, the general closure of the beach can deter visitors from the area entirely, impacting a broader range of local services.
-
Local Residents and Part-time Residents: While not generating direct revenue, residents who utilize Kamaʻole II for recreation will be unable to do so, potentially leading to altered local spending patterns if alternative activities are sought further afield.
Second-Order Effects
This localized advisory, if part of a trend of more frequent or longer-lasting advisories due to changing weather patterns, could have broader implications. Consistent beach closures, even for short periods, contribute to negative perceptions of destination reliability for tourism. This can lead to reduced word-of-mouth recommendations and, over time, impact long-term booking trends. Reduced visitor spending during these periods can also indirectly affect the supply chain for local businesses, from food distributors to equipment rental companies, creating a cascading effect on the broader Maui economy.
- Brown Water Advisories → Reduced beach accessibility → Lower immediate visitor spending → Decreased demand for local supplies → Strain on tourism-dependent supply chains.
What to Do
For Tourism Operators:
- Proactive Customer Communication: Immediately notify guests with upcoming bookings for activities at or near Kamaʻole II. Offer full refunds, rescheduling options, or alternative activities to maintain customer goodwill. Document all communications.
- Activate Alternative Offerings: If not already in place, have contingency plans for alternative land-based tours, cultural experiences, or indoor activities (e.g., cooking classes, historical tours) that can be promoted to guests during beach closures.
- Monitor Advisory Updates: Stay informed via the Hawaii Department of Health and local news outlets for updates on the advisory's lifting. This will help in quickly resuming scheduled activities and informing guests.
For Small Business Operators (Coastal-Adjacent):
- Adjust Staffing & Inventory: Consider a temporary reduction in staffing if foot traffic is severely impacted. Review perishable inventory for restaurants to minimize waste.
- Promote Non-Beach Activities: For restaurants and retail, consider special promotions for guests staying inland or engaging in alternative activities. Highlight indoor seating or unique local products.
- Engage on Social Media: Use social media to inform potential customers about the advisory and to promote your business's current accessibility and any adapted offerings.
Action Details:
Tourism operators should contact all guests booked for water activities at Kamaʻole II within the next 72 hours before 5 PM HST today. Offer a clear choice between rescheduling their booking for a later date, receiving a full refund, or substituting with an alternative land-based tour approved by your business. Small business operators adjacent to Kamaʻole II should assess immediate foot traffic and be prepared to adjust staffing and inventory levels within 24 hours, and by tomorrow morning, should consider social media posts highlighting alternative non-beach visitor experiences.
