These fish are usually found in tropical waters, so keeping this in mind we focus on figuring out where you can also find these species. Depending if the water is warm or not, the Red Snapper will migrate to either beaches or areas far away from humans. Fortunately for the fishermen, Cancun has both areas that include spots like Isla Mujeres and area’s along south of Sensuntepece . The time of year when you can find Red Snapper is January – April as they increase their reproduction rate at this time of year.
