What Is Lumot? Understanding Boracay’s Green Algae
If you’ve ever strolled along Boracay’s shores and noticed green strands in the water, don’t worry—it’s a natural part of the island’s coastal ecosystem. Locally known as lumot, this green algae is scientifically classified as Chlorophyta, and it thrives in both freshwater and saltwater environments.
In Boracay, these algae occasionally appear during certain months as soft, green threads that drift near the shoreline. While their presence might be surprising at first, they’re simply a seasonal feature of island life and are generally harmless.
For most visitors, lumot is nothing more than a visual change in the water. Those with sensitive skin might feel a slight irritation, but this is uncommon and mild. In fact, green algae are a vital part of the ocean food chain, providing shelter and nutrients for marine life.
The appearance of green algae in Boracay is influenced by a mix of natural conditions such as:
Warm sea temperatures
Calm and shallow waters
A natural increase in nutrients like nitrogen and phosphorus
These factors come together during specific times of the year, leading to what’s known as an algal bloom—a normal coastal event seen in tropical destinations around the world.
Understanding this natural phenomenon helps set expectations and allows you to plan your trip around the best seasons to enjoy Boracay’s famous white beaches and crystal-clear waters.

What Causes the Green Algae in Boracay
So, what’s causing these algal blooms in Boracay? The primary culprits are nutrient runoff and untreated wastewater, which provide ideal conditions for green algae to thrive. When excess nitrogen and phosphorus enter the sea, they contribute to a rapid increase in algae, especially during the dry season when warm temperatures and sunlight are at their peak.
This phenomenon is most noticeable during the warmer months, a common season in Boracay known for calm waters and higher visitor volume. As these conditions persist, algae growth becomes more expected, particularly in shallow and slow-moving waters where nutrients tend to accumulate.
According to the Department of Environment and Natural Resources (DENR), long-term nutrient buildup has played a role in the seasonal return of algae blooms along Boracay’s shores.
While this may cause worry for some travelers, it’s important to note that the algae are generally harmless and manageable. Understanding the seasonal patterns behind this natural occurrence allows you to plan your visit wisely and still enjoy the island’s stunning scenery.

When Algae Appears in Boracay
Avoiding Boracay’s green algae season largely depends on timing:
The algae are most prevalent between February and May.
April sees the most severe growth.
During this period, rising sea temperatures create the ideal conditions for algal blooms to flourish.
These seasons patterns are influenced by natural climate cycles, including the northeast monsoon, which leads to warmer waters. As a result, the shores of Boracay, particularly White Beach, can become quite crowded with algae during this season in Boracay.
To experience Boracay’s famous crystal-clear waters, plan your visit outside the peak algae months when algae are most noticeable.
Best Times to Visit Boracay to Avoid Algae
For those looking to dodge the algae, the best time to visit Boracay is from June to January. During these months, temperatures are lower, and the prevalence of algae diminishes significantly. November, in particular, stands out as an ideal month due to favorable weather and limited algae presence.
As the rainy season approaches in May, the algae begin to fade, making June a great time to start planning your trip. However, it’s worth noting that typhoons can occur between July and October, which might affect your travel itinerary. Always check the rainy weather forecast and plan accordingly to ensure a smooth and enjoyable visit.
