Jetty Diving
                                            A note about Jetty diving:
 Jetty diving is a unique type of diving experience. Options for jetty diving include Port Aransas or Packery Channel. At the Packery channel jetties, diving is done on the outsides of the jetty and not in the channel itself due to shallow depths and boat traffic. Depth is around 10'-15' near the end of the jetty, and current & visibility is often an issue here. Common species include Sheepshead, Snook, Gray Snapper, Schoolmaster Snapper, Blennies and Damselfish. Diving can be difficult due to the small size of the jetties themselves combined with the large amount of fishermen often there. In Port Aransas, diving can be done in the channel or on the beach sides of the jetty. Diving depth in the Port Aransas channel is around 40', and the beach side is about 15'. Currents in the channel can be too much to handle on some days and visibility is limited as a rule, but on a rare day, it may reach 30'. Species here include the same as at Packery, but also include small Groupers, Spotfin Butterflyfish, Octopus, Arrow Crabs, Eels, and just about any other inshore species you can think of. The South Jetty is easily accessible by car, but the North Jetty, which lies on St Jose Island, is only accessible by boat. Visibility on the North jetty is generally better than that of the south jetty due to prevailing wind direction. If you've never dived Jetties, there is a whole world you're missing out on just waiting to be discovered, and the best part is, you don't have to own a boat.

TURBIDITY- Port Aransas Jetties

Turbidity is defined as having stirred up or suspended particles, and is measured in NTU's (Nephelometric Turbidity Units). In layman terms, it is a numerical reading of how clear or dirty the water is. In more scientific terms, Nephelometric refers to the way the instrument, a nephelometer, measures how much light is scattered by suspended particles in the water. The greater the scattering, the higher the turbidity. Therefore, low NTU values indicate high water clarity, while high NTU values indicate low water clarity.
This link maintains a 24hr log of measurements taken hourly and the turbidity readings can be found near the bottom of the page under "Recent Observations". Generally speaking, a reading of 0 - 1 NTU's is good, 2 - 3 is moderate and stepping into the realm of limited visibility, 4 - 5 is really pushing your luck on being able to dive, and anything over 5 is a sign that you shouldn't waste your time driving out there. This isn't an exact correlation on visibility though, as other factors are at play, but this will give you a pretty good general idea of what the visibility is like before you load your car up and drive out there.

TIDES- Port Aransas Jetties

This is NOAA's tide prediction for any given day. Generally, the best time to dive the jetties for optimal water clarity is from just before high tide to about half way through the falling tide. It is best to plan to arrive just before high tide to allow time to set up you equipment, then begin your dive as the tide begins to slack.
