Weather & Sea Conditions

Q. What happens if the weather is not suitable for diving?

A. The weather can affect divers in different ways. Rain can help flatten and waves on the sea but it also brings silt down the rivers, which can then affect visibility. Wind will affect the surface conditions which can churn up shallow waters or make the access to and from a boat too dangerous. To help with this we have access to an indoor heated swimming pool, for all confined water training. For Open Water training, luckily we have 2 coastlines in Cornwall facing opposite ways, so there is usually somewhere not too affected by the wind to dive.

Q. What if the sea is not suitable for diving?

A. This can happen, at any time of the year, a combination of wind and rain can stop us diving in the sea. With this in mind we have permission to dive four local quarries, where we can achieve whatever depth is required for the course, or just to go for a fun dive. The closest it just 8m deep and is extremely sheltered, it can be used for all sorts of training that has no real depth requirement. The next closest quarry is 16m deep, it is suitable for any training that requires courses close to that depth, it is also good for photography and video courses with some nice scenic areas. A little further away we have a 30m deep quarry, this is good for depth progression dives, like that required by the Advanced Open Water. A similar distance away is our deepest quarry, at around 90m deep. Here we can complete any technical diving course that we teach.

Q. How cold does it get?

A. Sea temperatures range from 18 degrees, off the beach in the summer, to 7 degrees in the winter, although it usually remains around 10C for most of the winter. We dive all year round, wetsuits or semi-dry wetsuits can be used in the summer. During the winter we tend to prefer drysuits, water temperature isn’t really an issue it’s getting changed out of wet suits afterwards. Any quarries can be quite cold, dropping to 4 degrees at times, dry suits are a must for winter quarry diving.
