The Maldives Meteorological Service has issued a White Alert from Kaafu Atoll to Addu City, effective until 17:15 hrs today, predicting the likelihood of swell wave surges. This alert, valid from 13:15 hrs to 17:15 hrs, indicates a high probability of swell waves impacting the islands between Kaafu Atoll and Addu during high tide. According to the MET Office, wave heights could reach 2.8 feet at high tide in the Central Maldives and up to 3.2 feet in the Southern Atolls.
Recently, the Male’ Raalhugan’du area in Henveiru, as well as the southern side of Male’, experienced swell waves, continuing a trend observed over the past weekends. This period typically sees an increase in swell waves annually, which have historically caused extensive damage to many islands.
Climate change is anticipated to exacerbate the frequency and intensity of swell waves in the Maldives. Rising sea levels, driven by the melting of polar ice caps and the thermal expansion of seawater, contribute to higher baseline water levels, making islands more susceptible to wave surges. Additionally, changes in weather patterns and increased storm activity linked to climate change can lead to more frequent and severe swell wave events.
Mitigating the impact of swell waves and the broader effects of climate change requires a multi-faceted approach. Constructing and reinforcing coastal defences such as seawalls, breakwaters, and revetments can help protect vulnerable shorelines from the direct impact of waves. Mangrove restoration can act as a natural barrier against waves, reducing their energy before they reach the shore. Elevating infrastructure on stilts or elevated platforms can reduce damage from flooding and wave surges. Enhancing the accuracy and dissemination of early warning systems can ensure that communities are better prepared for impending swell waves and other climate-related events. Additionally, implementing and enforcing sustainable development regulations can minimise environmental degradation, which often exacerbates the impacts of climate change.
The increased incidence of swell waves can significantly impact the Maldivian economy, which is heavily reliant on tourism and fisheries. Damage to resorts, guesthouses, and infrastructure can lead to costly repairs and a temporary decline in tourist arrivals. Furthermore, the disruption of fishing activities due to adverse weather conditions can affect local livelihoods and the national economy. In the long term, failure to address the challenges posed by climate change and increasing swell waves could undermine economic stability and development efforts. Therefore, proactive measures and investments in resilience are crucial for safeguarding the Maldives’ economy and its communities.
By prioritising climate adaptation and mitigation strategies, the Maldives can better protect its natural environment, enhance the safety and well-being of its residents, and ensure the continued prosperity of its tourism and fisheries sectors in the face of growing climate challenges.
