A sash latch for retractable engagement with a side jamb of a window includes a lower member, which is fixed to a sash of the window, and an upper member with an extension. The upper member and extension slide relative to the lower member so that the extension can extend beyond the sash and can retract into the sash. In use, the extension extends beyond the sash and into the side jamb. A planar surface of the extension locks the sash to the side jamb. The extension also has a notch located opposite the planar surface. The notch prevents the extension from retracting into the sash when a heavy wind load is placed on the sash. Advantageously, this inhibits the sash from swinging dangerously inward under such a condition and reduces the possibility of damage or death.
