More than half of the Caribbean’s sandy beaches could disappear by 2100 under current sea level rise trajectories. For hospitality property managers, this is not an abstract environmental risk but a direct threat to revenue. Beach loss is already linked to room loss, with projections showing that around 30% of hotel rooms and nearly 40% of tourism revenue could be lost under average climate scenarios. In a region where tourism contributes greatly to economic stability, sea level rise is rapidly becoming a financial issue. Here we examine the data behind projected room losses and attempt to explain how proactive revenue protection strategies may help Caribbean resorts, and broader coastal hospitality in general decision-makers, face the consequences of sea level rise.
The Numbers Behind the Crisis
Physical exposure data
Sea level rise projections for the Caribbean range from approximately 0.5 to 1 meter by 2100 under mid-to-high emissions scenarios. This future exposure compounds a historical rise of about 15 centimeters over the past century. This change is already associated with retreat strategies and increased erosion pressure on sandy beaches.
A comprehensive study covering 30 islands in the region quantified how this physical exposure translates into hospitality impacts. Under a moderate climate model scenario of emissions (RCP4.5), the Caribbean could lose on average 53% of its sandy beaches, alongside a 30% reduction in hotel rooms and a 38% decline in direct tourism revenue by 2100.
Under a higher emissions pathway (RCP8.5), losses deepen to 59% of beaches, 39% of hotel rooms, and approximately 47% of tourism revenue. These three key numbers illustrate the critical correlation between beachfront capacity and increments in sea level.
Island-specific vulnerabilities
At the property level, exposure is highly concentrated. A geo-referenced CARICOM resort database indicates that a 1-meter sea level rise could directly inundate about 29% of coastal resorts, while erosion associated with the same rise could damage between 49% and 60% of properties.
Grenada provides a clear illustration of this escalation: with a 0.5 meters of sea level rise, roughly 60% of beaches are projected to be lost. At 1 meter, approximately 73% of tourism assets are placed at risk. In Saint Lucia, recent assessments indicate potential beach losses of 34% by 2100, with up to 57% of hotel revenue affected by shoreline change and related impacts. More densely built locations are at higher risk: in Barbados, about 80% of hotels are located within 250 meters of the high-water line, leaving limited margin for natural shoreline retreat.
Capital cost implications
Other dimensions of risk exist beside loss of room. Estimates aligned with UNDP assessments suggest that rebuilding damaged tourism infrastructure across CARICOM states could cost between USD 10 and 23.3 billion by 2050, rising to USD 23.5–74 billion by 2080 (2010 prices).
For individual states, these figures translate into macroeconomic stress. In Antigua and Barbuda, projected resort rebuild costs could reach 36% of GDP by 2050 and as much as 85% of GDP by 2080. This shows how neglecting coastal hospitality’s risk and exposure to sea level rise could critically affect national economies.

The Revenue Impact Cascade
Beyond physical asset loss
The truth in hotel management is that revenue erosion typically begins well before rooms are physically lost. As beaches narrow, usable space declines and carrying capacity plummets, weakening the attractive assets of beachfront properties. Hotels may still operate, but with reduced rate potential and lower occupancy as the desirability of its environment (the beach) deteriorates.
Guest perception accelerates this process. Visible erosion, degraded sand quality, and emergency or low budget coastal defenses can negatively affect guest satisfaction and destination image, with direct implications for bookings and repeat customers. Properties facing ongoing erosion also report higher maintenance costs and more frequent storm-related closures. The operating margins get compressed as the problem carries on.
Systemic economic risk
At scale, these property-level effects aggregate into a broader revenue risk for destinations. Tourism-dependent economies face declining employment, reduced tax receipts, and pressure on foreign exchange earnings as room capacity and pricing power erode. In Barbados, climate-driven tourism losses are estimated at USD 1.3 billion by 2050 and USD 7.6 billion by 2100, illustrating how revenue impacts extend beyond individual properties.
Many indirect losses remain overlooked. Shifts in investor confidence, rising insurance costs or loss of coverage, supply-chain disruptions, and long-term destination brand damage can significantly amplify direct revenue losses extending into the long term.
Non-linear risk dynamics
Sea level rise introduces non-linear thresholds that are particularly relevant for revenue protection. Horizontal shoreline retreats of only tens of meters can abruptly reclassify hotels from “prime beachfront” to “high-risk frontline,” which leads to sharp changes in valuation, insurability, and financing conditions. Because high-end resorts are often grouped in prime locations, localized erosion can cascade into destination-wide revenue impacts.
As mentioned earlier, once beaches degrade beyond a certain threshold, pricing structures and profitability can collapse rapidly rather than declining gradually. For hospitality decision-makers, recognizing these tipping points is central to protecting long-term room revenue and asset value.

Revenue Protection and Adaptation Strategies for Coastal Hospitality
The implication at the center of this issue is timing. Revenue protection hinges on how early properties and destinations act relative to shoreline change trajectories. Data from regional modeling shows that adaptation measures can significantly reduce projected beach and room losses when deployed proactively rather than after a coastal flooding event.
Protecting the beach asset itself is central. Beach nourishment is repeatedly identified as a cost-effective intervention at scale, with regional estimates indicating that maintaining beach width would require annual expenditures equivalent to roughly 0.9-1.1% of tourism revenue, far less than the 30-47% revenue losses projected without adaptation. For hotel operators, this reframes nourishment not as an environmental expense, but as a recurring revenue-protection investment.
Asset-level adaptation also plays a critical role. Elevating critical infrastructure, redesigning ground floors to accommodate periodic flooding, and using movable or sacrificial beachfront amenities can extend the operational life of exposed properties and reduce downtime following storm events. These measures help preserve room availability even as shoreline conditions evolve.
Strategic retreat and planning are equally important for long-term resilience. Integrating sea level rise projections into capital planning, refurbishment cycles, and new development setbacks allows operators to gradually shift room inventory out of the highest-risk zones, avoiding abrupt write-downs later. For destinations, coordinated coastal planning reduces the risk of maladaptive responses such as ad-hoc concrete seawalls that accelerate beach loss.
Taken together, these strategies highlight a central conclusion: sea level rise is already a material revenue risk for Caribbean hospitality, but early, coordinated adaptation can meaningfully protect room inventory, cash flows, and long-term asset value.
