Conditions for Diving in Phuket

Understanding Phuket’s weather is an important part of planning you scuba diving adventure. As the bulk of the scuba diving in and around Phuket is done off the large specifically built scuba diving boats.

A typical scuba diving day such as a certified day trip or PADI Discover Scuba Diving you could spend between 4 – 6 hours boat travelling. For the PADI Open Water Course or Advanced Open Water course you will do two days travelling.

The liveboard boats you will spend anywhere between two and eight days on board a vessel. This is one of the reasons why the liveaboard boats have a dive season of mid October to the end of April.

The weather in Phuket is warm all year round. Temperatures range between 25 – 34 degree Celsius or 77 – 93 degrees Fahrenheit. Humidity will range between 60% – 95% through out the year adding to the feeling of warmth.

The seasons are broken into two distinct seasons “Wet Season” (summer) and “Dry Season” (winter).

The driest months are between December and March (best time to scuba dive in Phuket) and the wet season from June to October.

The wet season along with the rain come high winds. With the high winds comes bigger waves which at times make the boat travel uncomfortable and sometimes dangerous.

A very good website in assisting in the prediction of wind, waves and rain is windguru.com

The best scuba diving will be between end of November and the end of April when the weather is dry and stable. The winds are soft and the waves smaller. May and November are transitional months and the weather can go both ways.

Do I Need to Know How To Swim to Scuba Dive?

This is a question that I often get asked, and really it is not as simple as YES or NO. If you want to become a certified scuba diver by doing the PADI Open Water Diver Course, the answer is yes. In the PADI Open Water Diver Course it is specified that you have to be able to swim 200 metres. This can be with any stroke. You also have to be able to tread water or float for at least 10 minutes. The reason for this is not for the fact that scuba diving requires you to swim. But rather it is for your and your groups safety. In the unlikely event that your BCD (Buoyancy Control Device) was to falter then there would be no device to kee [...]

Why is it Important to Stay Hydrated While Scuba Diving?

Staying hydrated when scuba diving is important to your health. Here we look at the reason why and the consequences if we do not.

There are a number of different reasons why a scuba diver may dehydrate, particularly here in Phuket, Thailand. Scuba Diving can also have its own issues if a diver does not keep hydrated. There are a number of factors that contribute the dehydration. Here is a list of a few that occur when scuba diving in warm climates like Ph [...]
