BEST TIME TO VISIT THE ANDAMANS FOR SCUBA DIVING

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.
