BEST TIME FOR SCUBA DIVING IN THE ANDAMANS

Best time for scuba diving in the Andamans

Let’s start by clarifying something – rain doesnt matter so much for diving. Yes, it can affect visibility at shallow depths, but this only happens when there is extended rainfall here (which doesnt happen often, even in the monsoons – we usually get short showers). Furthermore, most of our dive sites are off shore and once you descend to the dive depths, conditions arent affected so much. Tides play a much bigger role in affecting underwater visibility and that changes from week to week – so the range of visibility remains more or less the same all year long, whether it is raining or sunny.
What matters more is wind. When it is too windy, the seas are rough and we cannot go out to the open sea (or sometimes, we can go out but decide not to, in order to be safe:  our standard isnt “can we dive in this”, but “if something were to go wrong, can we manage the situation safely for everyone in this”). However, even when it does get rough, we have a bunch of sites that are accessible all year long as they are sheltered from prevailing winds – what we cannot do is visit our remote, highlight sites like Johnny’s Gorge, Dixon’s Pinnacle and Jackson’s Bar. This doesnt affect beginners so much, but does affect certified divers.
Traditionally, this is what the weather holds over the course of the year:

 

January-May period is when the seas are the calmest (especially March-May, when the sea is sometimes to calm that it resembles a mirror) and surface conditions are best for diving.

 

June – August is the rainy season. This is different from the mainland monsoons, and consists of wet periods (when it is cloudy all day and there are frequent, brief showers) and dry periods (when it is sunny and calm for several days or even weeks). During some of this time, we are able to visit all our highlight sites and at other times, we are restricted to the nearby, sheltered sites.   While the diving is usually fantastic due to fish spawning in the warmer water, odds are higher that we will be limited to our nearer sites. However, the weather is usually very pleasant at this time, the package tourists are away and the island reverts back to a sleepy, idyllic paradise.

 

September-November is what we call the “new season” – during this time, the south-westerly winds are starting to die down, but there are still regular showers and occasionally, the winds do pick up. At this time, the diving is absolutely fantastic (a lot of fish spawn in the rainy season, so there is a lot of bio-mass on the reefs) and the sites are at their absolute best. The flip side, of course, is the slightly higher risk that winds may play spoilsport and limit us to nearer sites.  Also, currents can be stronger at this time.

 

December is a bit of a transition time – the terrestrial weather is lovely, sometimes there are showers and the winds can be moderately strong.
Of course, with weather patterns changing over the past 5-6 years, things are a little more blurry now. Over the past 3-4 years, we’ve had very calm conditions in June, with low wind and limited rain. We’ve also had rough conditions in Jan/Feb. At this point,

 

What does this mean?

 

FOR BEGINNERS: It doesnt matter when you come. We have sites that are accessible all year long, even in a storm, and the conditions of these sites usually do not vary that much whether it is on or off-season. In season, things are sunny and the islands are busier – in the off-season, it is quieter, things are more relaxed and the weather is actually very pleasant. And because the rain takes the form of brief showers, you can actually explore the islands without any issues).

 

FOR EXPERIENCED DIVERS: Based on the recent weather trends over the past 5-6 years, we’ll say that March/April/May offer the best chances of calm conditions,  followed by January/February, followed by September-December.     Conditions in June, July and August can vary – if you are lucky, you’ll get superb diving with just 2-3 people on the boat, and if you are unlucky, you’ll be limited to our nearer sites (which are very nice, but probably a step or so behind our highlight, open-sea sites).
Of course, the weather being what it is, there are no guarantees but hopefully, this will help provide some information in helping you plan your trip to the Andamans.

An old “friend” returns?

Back in 2002, I was teaching a class at Minerva Ledge with 3 Open Water students.
Back then, there used to be a lot more sharks on this reef and the question wasnt whether we’d see any sharks, but how many and which species. As with most beginners, my students had some concerns about being in the water with sharks, and I gave them my usual spiel: sharks arent dangerous, we are not normal prey, we are too big for most sharks, etc. etc.
We get in the water, and sure enough, we see a white tip cruise by. And then a black tip some time later. By now, my students are converted – they are very excited about the sharks and no longer scared. Towards the end of the dive, yet another white tip goes by – and a few seconds later, one of my students points to the right into the blue and signals “shark.”
I look, expecting to see a white tip and sure enough, there is one swimming towards us. I nod and return to scanning the front, as I am hoping to get a manta today.
Then a small voice pipes in my head, saying “wait a minute – wrong proportions…” I look again, and the shark is coming toward us. Directly towards us. Fins down. Which is an aggressive territorial display.
“Wait a minute,” I remember thinking, “where does a white tip get off being aggressive to three divers”?
Then the initial voice in my head pipes up again “hey… WRONG proportions. Hellooo!”
Right – when looked more closely, this shark just seemed to be a lot bulkier. And not only that, it was a lot bigger. And at that moment, it turned and showed us its size – it was a 4m+ bullshark! Yes, I know bullsharks don’t get bigger than 3m or so – but this was 4m+ and I will stake my diving reputation on it (heck, most people who’ve seen it put it at 5m+, but that is a bit exaggerated). And my divers and I had just been told off in no uncertain terms by Big Guy that we were in his territory. Rather than upset him, we turned around and head back in towards the reef, and that was all we saw of him on this dive.
Over the next few years, Bob the Bullshark would make a reappearance a couple of times each season. Each time, it was at the same site and the same deal: comes straight in, fins down, in a territorial display, turning away a good 10m or so away. We always appreciated the polite warning and would make sure we didn’t hang around for a second pass (and certainly not the third pass, which might involve a “smile”).
And each sighting was absolutely, gloriously epic – there are few things in this world as graceful as an enormous, powerful shark with rippling muscles and gliding by faster than anyone can swim with the merest flick of its tail. It was humbling and it was moving – we were witnessing one of nature’s 2 perfect creations in its element (the other being the crocodile) – and I mean “perfect creation” literally: the shark has not changed or evolved over 350 million years. It is perfect and cannot be improved upon.
The last 3+ seasons, Bob has been AWOL. We put it down to him falling a victim to the local shark fishermen (thanks to the demand for turning this amazingly beautiful animal into soup).
However, a couple of days ago, two of our divers and one of our DMs saw a big shark at a site that is about 250m away from Bob’s old stomping grounds. Initially, we were not sure whether it was a grey reef shark (which has been sighted here occasionally) or a bullshark (which has never been sighted here). Speaking to the divers and comparing notes on size, shape, etc., I am pretty confident it was a big bullshark.
Could Bob be back? I for one certainly hope so – if there ever was a Christmas present that would thrill me beyond belief, this would be it. And at the risk of anthropomorphizing too much, I do wonder if somewhere in that predator mind of his, Bob remembers us?
Welcome back, Bob – we missed you!
