When To Go
Season planner for Semporna (Sipadan, Mabul, Kapalai)
Semporna diving runs year-round, but conditions shift with Sabah's monsoon patterns. Many travelers target April to October for calmer seas and better visibility, while November to March can bring more rain, wind, and choppier crossings. Water temperature is usually stable around 27°C to 29°C. Sipadan access depends on permits, and conservation-driven closures have occurred (often discussed around November), so confirm park dates when planning.

Activity Drilldowns
OverallApril to October·Crowd:Moderate·Cost:Moderate
Ideal: Calmer seas and better odds of clearer visibility on crossings; warm water around 28°C.
Plan Carefully: Northeast monsoon influence can bring heavier rain and stronger winds (often up to 25.0 kph), making boat rides rougher and visibility more variable.
If Sipadan is your priority, permits matter more than season.
ScubaApril to October·Crowd:High·Cost:Premium
Ideal: Best mix of calmer seas and consistent dive operations. Expect 10 m to 30 m depending on rain and tide.
Plan Carefully: More weather variability and rougher crossings. Some years may include Sipadan conservation closures around November.
Sipadan dives are currentdriven and can feel more intense during windier months.
FreediveMay to September·Crowd:Moderate·Cost:Moderate
Ideal: More frequent calm mornings for line sessions and clean reef descents. Surface chop is typically lower.
Plan Carefully: Wind and chop can limit safe buoy work. Favor sheltered reefs near Mabul and Kapalai over exposed corners.
Freediving quality is very daydependent.
SnorkelApril to October·Crowd:Moderate·Cost:Moderate
Ideal: Calmer surface conditions for comfortable floating and clearer water on shallow reefs.
Plan Carefully: More rain and chop. Use a guide, wear fins, and consider a snorkel vest for extra stability.
If you are sensitive to motion or waves, schedule snorkeling earlier in the day and keep crossings short by prioritizing Mabul and nearby reefs.
TopsideMarch to September·Crowd:Moderate·Cost:Moderate
Ideal: Better odds of drier mornings for the Bohey Dulang hike and clear views over the crater lagoon.
Plan Carefully: Wetter months can reduce visibility for viewpoints and make trails slippery.
For Bohey Dulang, bring water and sun protection even in wet season.
