In the peak the summer season, the waters at Blue Springs Park can reach the upper 80’s at the surface down to the first thermocline. With the size of the quarry there are typically 2 thermoclines making for 3 separate temperatures at depth. Between the 1st and 2nd the temperature can vary 10 to 15 degrees below the current temperature. Below the 2nd thermocline the water stays in the 40’s to the bottom. We always recommend 7mm wetsuits with hood & gloves or dry suit when making a deep dive. As with most dive quarries, the water is chilly the deeper you go but unlike others you won’t typically need dive light due to the clarity of the water and sunlight. But don’t take our word for it, check out some of our trip adviser reviews from other divers that have experienced the difference for themselves.
