St. Joe's Island, just north of the Port Aransas Jetties, is an uninhabited isle that extends from Port Aransas all the way to Matagorda Island. This spot can be a hidden gem for surfers looking to catch some waves, especially when other beaches are getting blown out by the wind. It's a good option for those in search of cleaner surf, particularly during large, wind-driven swells from the south.

The surf at St. Joe's can be decent, especially on days when the swell is coming in from the south or southeast. You can expect waves in the chest-high range (around 1.2 meters) to a couple feet overhead (up to 3 meters) on good days. The wave types here mostly break over sand, with options for both right and left waves. The best conditions tend to come with low to mid to mid-high tides. If the wind is from the northwest, west, or even north, it can work out quite well. The jetty provides some shelter from the south winds, which can make for better surf even when other spots are struggling. This spot can handle swells from 1.5 meters to 3 meters (5 to 10 feet), catering to all levels of surfers, from beginners to experts.

Getting access to St. Joe's can be a bit tricky, especially if you’re thinking of paddling across the channel, which can be dangerous due to large vessels. The safest bet is to reach it by boat or ferry. The crowds here tend to be sparse, so you'll have some space to enjoy the waves. It’s a nice place for a more laid-back vibe, especially during the late summer and fall or late winter through mid-spring, when conditions are generally more favorable. You can ride shortboards, funboards, longboards, or even fish depending on what you prefer for the day.
