The website is the guide and go to website for not only all scuba diving and boating agencies in Phuket but the world wide.

Given that all of the scuba diving in Phuket is involved a lot of boat travel (anywhere from 1.5 hours for Racha Yai and three hours for Phi Phi) most scuba diving rely on it heavily for information for the safety and enjoyment of their customers.

Often divers particularly those doing beginner course such as the PADI Discover Scuba Diving or PADI Open Water Course have never been on a boat for extended periods. Given that it is their first experience at scuba diving we try to make it as enjoyable as we can.

Often we provide the website to divers to assist them in planning their dives whist in Phuket. To the untrained eye it look like a lot of lines and colours and really doesn’t make a lot of sense.

Hopefully this blog will help a little.

Understanding Phuket Weather Blog

On the website there are two very important features regarding boat travel and they are wind speed/gust and wave height. The stronger the wind the larger the waves. The larger the waves the more uncomfortable and sometime dangerous the boat trip can be.

To a lessor extent rain is also an issue. Not that rain itself effects the diving to much but it does effect diver comfortability. As you will spend long periods on the boat, being wet for most of the day is not pleasant.

Wind and Waves

Way back in 1807 navel officer Francis Beaufort designed a wind – wave scale based on his observations at sea (and land). This scale has since become the guide to understand the correlation between the wind speed and the subsequent wave height. Basically, the stronger the wind, the bigger the waves. The bigger the waves the more uncomfortable the day scuba diving trip will be.

Beaufort Scale – Aussie Scale

Wind Speed Wind Description Wave Height Sea Conditions Aussie Divers Scale
Lees than 1 Knot or 1km/h Calm 0m Sea like a mirror What are you doing on land? Get out there and dive!
1 – 3 Knots or 1 – 5km/h Light Air 0 – 0.2m Ripples with the appearance of scales are formed, but without foam crests The surfers loss is the scuba divers gain – go diving!
4 – 6 knots or 6-11km/h Light Breeze 0.2 – 0.5m WindGuru 3-4 knots 0.5m Small wavelets, still short but more pronounced; crests have a glassy appearance and do not break Nothing to worry about – Just don’t leave your drink on the table
7 – 10 knots or 12-19km/h Gentle Breeze 0.5 – 1m WindGuru 7-10 Knots 0.7m Large wavelets. Crests begin to break; scattered whitecaps Still a good day out. If you are prone to motion sickness take medication way before the boat ride
11 – 16 knots or 20-28km/h Moderate Breeze 1 – 2m Windguru 11-15 Knots 1.2 metre Waves Small waves with breaking crests. Fairly frequent whitecaps. 1.0 – 1.5m: The boat will move a bit. Medication for most. For those that get seasick, one tablet the night before and one first thing in the morning. 1:5 – 2.0m: The boat will move a lot and if you don’t like rocky boats please take this into account
17 – 21 knots or 29 – 38km/h Fresh Breeze 2 -3m WingGuru 17 - 25 Knots 2.5m Moderate waves of some length. Many whitecaps. Small amounts of spray. If you come from a family of sailors, fishermen or pirates not a problem. Everyone else start looking at other things to do. Boats could cancel in this weather.
22 – 27knots or 38 – 49km/h Strong Breeze 3 – 4m WindGuru 23-26 knots 3.4m Long waves begin to form. White foam crests are very frequent. Some airborne spray is present. You may as well stay at home as we will be. No boats will operate.

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. Here is some explanations and reasons why. 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 continuously for 200 metres. This can be with any stroke however it does need to be continuous without stopping. There is alternate option and that is you do a 300 metre mask, fin and snorkel swim. Some do find this easier to the 200 swim. You also have to be able to tread water or float for at least 10 minut [...]
