A beach umbrella provides an elongated support shaft having a pointed distal end inserted into a soft surface, and a proximal folding canopy positioned below an upper terminal end of the support shaft. The folding canopy provides a fabric panel stretched over a plurality of ribs engaged with the support shaft and extending radially from it to form a downwardly convex external surface. A flexible strap is attached over the upper terminal end of the support shaft and an opposing eyelet engaged with the tip of one of the ribs of the umbrella. A securing line is fixed at a distal end to a stake driven into the surface so the line forms a downwardly divergent angle with the support shaft. The flexible strap lies in contact with the external surface of the fabric panel and is joined at its upper end with the strap. Strap and line are arranged to point upwind to counter wind forces so that the umbrella cannot be blown over.
