Why this matters
A barrier island moves. Wind, waves, currents, storms, vegetation and human work reshape beach width and dune form, so no photograph represents a permanent edge.
What to compare
Separate short-term storm loss from long-term shoreline trend, and separate a nourished town segment from wild north beach or Boca Chica. Dates and measured reaches matter.
What changes
New storms, projects and monitoring cycles can alter the visible beach and the official interpretation. Dune recovery can be slower than a visitor season.
Make the next decision
Use designated walkovers, leave vegetation and fencing in place, and consult current city and Texas General Land Office plans before describing a project, erosion rate or access change.
Current source
Use Texas General Land Office coastal resources for the current operational detail. Check its date, location and scope before allowing a price, time, rule, forecast or availability statement to control the trip.
