How many dives can you do in a day?

At some point during open water class a student will ask how many dives they can do in a day. The answer to that is a big “that depends”. I know that is so vague that it begs to be answered, but first let us define a dive as using a tank of air.

So, just how many dives can you do in a day? Well, are they fun dives or training dives; that is taken in conjunction with a class? PADI standards say that we can do no more than 3 training dives in a day, so that answer is very clear. So how can you do your Open Water and Advanced Open Water in a long weekend or your Advanced Open Water and Rescue in a long weekend? The key word is long as in 3 day weekend. If PADI standards say we can do 3 dives in one day and we need to make 4 dives for open water and 5 for advanced open water it will take 3 days. Dive planning will be a huge part of your weekend and that is a great thing.

Can you combine training dives and fun dives in one day? Of course you can. If you finish your open water training dives in the morning and want to go out on the boat that afternoon and do a 3 tank trip, you can do that. Plan your dives accordingly with your instructor and dive buddy.  How deep are your dives going to be and how long?

So just how many dives can you do in one day? Again, that depends on you and your buddy and how you plan your day and what gas is in your tank. On the liveaboards, we generally do 4 to 5 a day. The dives are generally about 80 feet and for close to an hour with at least 90 minutes or so between dives and yes we are diving computers and nitrox. But, if we are going to explore a shallow reef at so 40 feet on regular air with 90 minute surface time we can probably make 5 or 6. Change air to nitrox and you can cut your surface time to 60 minutes and easily make 6 maybe 7.

So how many dives can you do in one day? That depends on you and your dive planning skills.
