I can't speak to what the inlet is like at this very moment, but I've used it a few dozen times over the past several years and find that it does shift, but they are very good about shifting the markers accordingly. It's been referred to as a local knowledge recommended entrance as long as I've been using it, but I find it much more straight forward than many further south. Even the warning quoted above mentions they are shifting the mark as the bar changes.
That said, if you have any doubt, it's not much farther to just head
directly to the Fort Pierce inlet if heading north. It may be one of those things where you will want to consider what the light, wind
, and tides are predicted to be like when you would arrive.
