Semporna Malaysia Guide 2026: Flights, Weather & Sipadan Diving

The Ultimate Semporna, Malaysia Travel Guide

Flights, Weather, and Diving Tours Explained

If you are thinking about planning a trip to Semporna, Malaysia,

chances are it started with a single question:

"Can the ocean really be this unbelievably clear?"

That is exactly how my curiosity began.

I was searching for travel inspiration when one photo of Semporna completely won me over.

Known as one of Malaysia's premier diving meccas,

Semporna more than lives up to its legendary reputation.

Every island boasts a different shade of blue, and the vibrant marine ecosystems

make you feel truly connected to the ocean.

It is a destination where

both beginner and advanced divers

can find their ultimate bucket-list experience.

Another massive draw? It is still relatively under-the-radar for Western tourists.

Unlike Bali, Bohol, or even nearby Kota Kinabalu,

Semporna hasn't been overrun by massive crowds.

It retains an authentic, local charm

that lets you soak in that signature laid-back Malaysian vibe.

The sight of traditional water villages floating above the sea

offers a cultural atmosphere

that is incredibly hard to find anywhere else in Southeast Asia.

However, planning a trip to Semporna requires a bit of logistics.

Figuring out flights, understanding the weather patterns,

and booking diving tours can feel overwhelming at first.

But once you break it down, the itinerary comes together beautifully.

I have compiled everything I learned from my own research and travels.

If you are feeling a bit lost planning your 2026 adventure,

this guide is exactly what you need.

1. Flights & How to Get There

The most important thing to know about traveling to Semporna is that

Semporna does not have its own airport.

You will need to fly into Kota Kinabalu (BKI),

take a domestic flight to Tawau (TWU), and then drive.

There are no direct international flights to Semporna,

so expect at least one layover depending on your origin.

A typical route looks like this:

International Hub → Kota Kinabalu (BKI)

→ Tawau (Domestic Flight) → Semporna (1-Hour Drive)

When searching for flights, make sure you use the official spelling, "Semporna,"

as some booking sites occasionally misspell it.

The domestic leg from Kota Kinabalu to Tawau

sells out quickly, so book well in advance.

During peak seasons (July-September and December-February),

these domestic flights are packed,

so choosing a layover schedule that gives you plenty of buffer time is crucial.

Because travelers often land late at night or early in the morning,

many choose not to head straight to the islands.

A popular itinerary is spending one night near the Kota Kinabalu airport,

or getting a massage upon arriving in Semporna before checking in.

2. Weather & Best Time to Visit

Semporna boasts year-round warm weather,

but if you are coming for the diving,

you definitely need to understand the seasonal shifts.

✓ Dry Season (March - October)

The ocean is relatively calm, and visibility is crystal clear.

This is the absolute best time for diving,

and tours to Kapalai and Sipadan operate flawlessly.

Because the weather yields those perfect, postcard-worthy photos,

the majority of divers flock here during these months.

✓ Wet Season (November - February)

You will encounter frequent rain, but usually in the form of quick tropical squalls that pass fast.

The waves can be a bit choppier, and visibility might drop on certain days.

However, it is definitely not a "do not visit" season.

Just keep in mind that Sipadan diving permits sell out faster during these months due to limited operating windows, so plan ahead.

✓ Temperatures

Air temperatures average between 79°F and 88°F, but the humidity makes it feel warmer.

The temperature doesn't fluctuate much from morning to afternoon,

but the wind can make you feel a bit chilly during fast boat rides.

✓ Ocean Conditions

For divers, water temperatures hover between a balmy 81°F and 86°F,

so a thin wetsuit or rash guard is usually plenty.

If you are spending hours on a boat, a dry bag for your phone and extra GoPro batteries are essential.

When preparing for your Semporna trip,

I found that checking weather apps wasn't as helpful.

Instead, check the real-time Instagram or Facebook updates from local dive resorts.

They frequently share live updates on current shifts and visibility,

which is incredibly useful right before your trip.

3. World-Class Diving

The absolute highlight of a Semporna vacation is,

without a doubt, the diving.

For beginners, the calmer waters around islands like Mabul and Bum Bum are perfect.

But if you are an experienced diver with a solid logbook,

Sipadan is an absolute non-negotiable.

Sipadan is a highly protected marine area,

with access strictly capped at just

180 permits per day.

Because of this, the competition to book a Sipadan dive tour is fierce.

You must book this well in advance before leaving home;

trying to secure a permit once you arrive in Semporna is nearly impossible.

Here is a quick breakdown of the main diving hubs:

1) Sipadan

From massive schools of sea turtles and swirling barracuda tornadoes to whitetip reef sharks,

this place offers everything a diver could dream of.

The currents can be strong, so it is best suited for intermediate to advanced divers.

2) Mabul

A holy grail for muck diving and underwater macro photography.

If you love spotting tiny critters like frogfish and ghost pipefish,

Mabul is perfection.

It also offers a tranquil atmosphere with plenty of great photo ops.

3) Kapalai

Famous for its stunning overwater resorts.

The transit time from the resort to the dive sites is incredibly short, making it super convenient. It is perfect for beginners or travelers looking for a less physically demanding day.

Even if you are not a certified diver,

you can still do a Discover Scuba Diving (DSD) experience.

Many operators offer packages that combine

boat tours, island visits, and beginner dives.

4. Island Hopping Tours

If you aren't into diving, Semporna's

island hopping tours are legendary in their own right.

Each island has a distinct water color and diverse snorkeling spots,

meaning you can have an unforgettable trip without a dive certification.

Here are the most popular tours:

✓ Bohey Dulang Tour

The water here is literally as transparent as glass.

The hike to the viewpoint is an absolute must for photographers.

✓ Vaabong Snorkeling Tour

Most tour operators offer highly reasonable prices

that include hotel pickups, gear rentals, and breakfast or snacks.

Planning a trip to Semporna, Malaysia

definitely takes a bit of puzzle-solving.

From charting out flight connections and monitoring weather seasons

to gauging your diving level and picking the right island tours,

it requires some thoughtful preparation.

But the moment you step onto that boat and look down into the water,

you will instantly understand why travelers from all over the globe

call Semporna a once-in-a-lifetime destination.

If Semporna is on your 2026 travel radar,
