The Best Times for Diving Around the Gili Islands: What Every Diver Should Know
The Best Times for Diving Around the Gili Islands
The Gili Islands—Gili Trawangan, Gili Meno, and Gili Air—are often described as paradise on earth. With their white-sand beaches, turquoise waters, and laid-back charm, they’ve become one of Southeast Asia’s top destinations for divers of all levels. Whether you’re a newly certified Open Water Diver or a seasoned professional, the Gilis offer a diving experience that’s hard to beat. But the question many divers ask before booking their holiday is: When is the best time to dive the Gili Islands?
The answer isn’t just about the weather or visibility—though those play a major role. It’s also about the kind of dive experience you’re after: do you prefer quiet reefs teeming with life, or a social diving holiday with lots of fellow underwater enthusiasts? In this article, we’ll explore what each season around the Gilis has to offer and why certain months might be more ideal depending on your preferences. We’ll also share how Oceans 5 Gili Air ensures a quality dive experience year-round, even during the busiest months.
Understanding the Seasons Around the Gilis
To understand the best times for diving, it’s helpful to break the year down into three distinct periods:
- High Season: June to October
- Peak Season: July and August
- Quieter Season: March to June & October to November
Let’s dive into what each season has to offer for divers.
High Season: June to October
This is the most popular time of year to visit the Gili Islands. With dry skies, calm seas, and great underwater visibility, it’s easy to see why. Water temperatures hover between 28-30°C, and the coral reefs are vibrant and full of life. Visibility often reaches 20-30 meters, making it the perfect time for wide-angle photography and spotting larger marine life like reef sharks and turtles.
However, popularity has its trade-offs.
Pros:
- Excellent visibility and warm water
- Peak season for marine life activity
- Perfect conditions for diving courses and underwater photography
- Social atmosphere at dive centers and island-wide
Cons:
- Crowds. July and August are the absolute peak, and it can feel like everyone is on the same dive boat as you.
- Packed dive sites. Famous dive sites like Shark Point, Turtle Heaven, and Halik can become crowded with groups of divers, all eager to explore the same reef.
- Advanced bookings required. Dive courses, fun dives, and accommodation can fill up quickly during this time, especially if you’re aiming to train with a top-rated dive center.
At Oceans 5 Gili Air, even during these packed months, we maintain a maximum ratio of 4 customers per instructor or divemaster. This ensures that you’ll still get a high-quality, personalized experience regardless of how full the boat might be. That policy reflects our belief that diving should never feel rushed or impersonal—something often lost at larger operations during peak periods.
Peak Season: July & August
While technically part of the high season, July and August deserve their own category. These months coincide with European summer holidays, so it’s the busiest time of year across the islands. Dive shops are bustling, restaurants are full, and accommodation is often fully booked weeks in advance.
If you’re a diver who thrives on social energy and meeting like-minded people, this may be the perfect time for you. You’ll meet divers from all over the world, enjoy lively beach nights, and dive in perfect tropical conditions. But if your idea of paradise is a quiet reef shared with just your buddy and a curious turtle, you might want to plan around these months.
At dive sites like Shark Point and Meno Wall, you’ll likely see more bubbles than fish if you’re diving with larger groups. However, Oceans 5 Gili Air does its best to avoid the crowds. Our experienced dive team knows the sites inside out and will plan around peak times, heading out early or choosing alternative dive spots to give you a more peaceful experience whenever possible.
The Ideal Window: March to June & October to November
Now let’s talk about what we believe is the best time to dive the Gili Islands: March to June and October to November.
These shoulder-season months offer the perfect balance. The islands are less busy, the dive sites are more relaxed, and the marine life is just as active as during the high season. Visibility is still fantastic, and the water remains warm and welcoming.
Why Choose These Months?
- Fewer crowds. Whether you’re diving at Halik, Turtle Heaven, or Bounty Wreck, you’ll often have entire sites to yourself or with just a handful of other divers.
- Gentler conditions. The currents are usually milder than in peak season, making it a more enjoyable experience for newer divers or those prone to seasickness.
- More flexibility. With fewer students and fun divers, you’ll have a better chance to choose dive times, courses, and personalized guidance.
- Nature at its best. You’ll still see turtles on almost every dive, schools of jackfish, cuttlefish, and even the occasional blacktip reef shark.
- Perfect for underwater photography. With fewer divers stirring up sediment, the conditions are great for macro and wide-angle shots alike.
- Still plenty to do on land. While the islands are quieter, businesses are still open, yoga sessions continue, restaurants serve fresh seafood, and sunsets are as breathtaking as ever.
At Oceans 5 Gili Air, we often recommend these shoulder-season months to guests who ask for the “real Gili experience.” It’s quieter, more personal, and lets you connect with both nature and local culture in a more meaningful way.
What About December to February?
These months are part of the rainy season in Indonesia. While diving is still possible and many dive shops—including Oceans 5—remain open, you may experience occasional rain showers and choppier seas. The visibility can vary, and there are more days with stronger currents and waves, especially during January and early February.
However, the Gili Islands are in a relatively dry microclimate compared to other parts of Indonesia. Even during rainy season, it often rains only in short bursts, mainly at night or early in the morning. Some divers actually enjoy the rainy season because it’s even quieter, and accommodation is cheaper.
If you’re an advanced diver looking to explore muck diving sites or enjoy macro photography, the rainy season also brings out a variety of unique critters around nearby Lombok dive sites such as Teluk Nara and Mentigi Bay.
Still, for a first-time visitor hoping to experience the full beauty of the Gilis, we suggest sticking to the drier and calmer months.
Month-by-Month Breakdown
Here’s a quick guide to what you can expect throughout the year:
| Month | Conditions | Crowds | Dive Highlights |
|---|---|---|---|
| January | Rainy, windy | Quiet | Unique critters, occasional rough sea |
| February | Rainy, variable | Very quiet | Macro life, some strong currents |

| December | Unpredictable | Moderate | Holiday crowds, but variable diving conditions |
Why Choose Oceans 5 Gili Air Year-Round?
Regardless of when you visit, Oceans 5 Gili Air makes your dive experience exceptional. Whether it’s peak season or the quiet months, we keep our group sizes small, never exceeding 4 divers per guide or instructor. This isn’t just about luxury—it’s about safety, comfort, and giving you the best chance to learn, relax, and enjoy the underwater world.
Our dive team includes highly trained professionals who’ve been diving these sites for years. They know how to find turtles hiding behind corals, where the pygmy seahorses like to chill, and how to read the tides and currents to keep your dives fun and safe.
We also schedule our dive departures strategically to avoid the crowds. While other boats rush out at the same time every day, we stagger our trips to visit the best sites when they’re the least busy.
More Than Just Diving
If you’re traveling with non-divers, visiting during quieter months makes the entire trip more enjoyable. Gili Air is vibrant all year—there are still yoga classes, cooking workshops, traditional music events, and plenty of beachfront dining. And let’s not forget those epic Gili sunsets, best enjoyed with a coconut in hand and your feet in the sand.
