Coron High & Low Tide Today

Geographic Overview

Coron is a municipality on Busuanga Island in the Calamian Islands group at the northern end of Palawan province. The town of Coron sits on the southeastern coast of Busuanga, overlooking Coron Bay and the island of Coron Island directly across the water. Coron Bay is surrounded by the mountainous islands of the Calamian group, creating a sheltered inland sea. Coron Island itself hosts a series of freshwater and saltwater lakes set within the limestone karst interior, most notably Kayangan Lake. The area is separated from the main Palawan landmass by Linapacan Strait.

Tidal Characteristics

Coron and the surrounding Calamian Islands experience mixed semidiurnal tides with moderate diurnal inequality. The sheltered nature of Coron Bay moderates wave action significantly, but tidal range remains comparable to the broader Palawan pattern — typically 0.9 to 1.5 meters. The enclosed lakes on Coron Island (Kayangan and Barracuda Lakes) are connected to the sea through subsurface channels and respond to tidal forcing with a lag, creating a halocline — a visible boundary between fresh and salt water at depth — that is a notable feature for divers visiting Barracuda Lake.

Best Times to Visit

Coron is positioned to receive the amihan (northeast monsoon, November–May) more directly than El Nido to the south. The amihan period brings calmer seas and lower rainfall — the ideal window for wreck diving and island exploration. The habagat (June–November) affects the area less severely than the western Palawan coast, though boat operations can still be disrupted by strong winds. October through May is the practical diving season. Peak crowds occur from December through March, coinciding with both the best weather and school holiday periods.

Safety Tips

Wreck diving in Coron Bay requires proper certification and dive briefings; the Japanese shipwrecks lie at depths ranging from 10 to 42 meters, and several are penetration dives requiring additional training. Thermoclines inside Barracuda Lake can cause disorientation — buoyancy control is critical. Kayangan Lake involves a steep staircase walk from the boat landing and can be crowded midday; early morning visits are both less crowded and cooler. Boat traffic within Coron Bay is substantial during the tourism season — dive flags are essential. The freshwater lakes require the removal of sunscreen before entry to protect the ecosystem.

What Makes It Special

Coron Bay contains one of the most accessible wreck diving sites in the world — a fleet of Japanese supply ships sunk by American aircraft in September 1944, now resting on the bay floor at diveable depths. The wrecks are large, well-preserved, and encrusted with coral and sponges after eight decades, making them attractive to both divers and marine life. Kayangan Lake, often described as one of the cleanest lakes in Asia, sits inside a dramatic karst bowl and features clear water with visibility extending to the rocky bottom. The combination of wreck diving, lake exploration, and reef snorkeling within a compact and sheltered bay makes Coron a multi-activity destination with genuine depth.
