The shape of depth-limited breaking-wave overturns is important for turbulence injection, bubble entrainment and sediment suspension. Overturning wave shape depends on a nonlinearity parameter
$H/h$, where
$H$ is the wave height, and
$h$ is the water depth. Cross-shore wind direction (offshore/onshore) and magnitude affect laboratory shoaling wave shape and breakpoint location
$X_{{bp}}$, but wind effects on overturning wave shape are largely unstudied. We perform field-scale experiments at the Surf Ranch wave basin with fixed bathymetry and
$\approx 2.25$ m shoaling solitons with small height variations propagating at
$C=6.7\ \mathrm {m}\ \mathrm {s}^{-1}$. Observed non-dimensional cross-wave wind
$U_w$ was onshore and offshore, varying realistically (
$-1.2 < U_{w}/C < 0.7$). Georectified images, a wave staff, and lidar are used to estimate
$X_{{bp}}$,
$H/h$, overturn area
$A$ and aspect ratio for 22 waves. The non-dimensionalized
$X_{{bp}}$ was inversely related to
$U_{w}/C$. The non-dimensional overturn area and aspect ratio also were inversely related to
$U_{w}/C$, with smaller and narrower overturns for increasing onshore wind. No overturning shape dependence on the weakly varying
$H/h$ was seen. The overturning shape variation was as large as prior laboratory experiments with strong
$H/h$ variations without wind. An idealized potential air flow simulation on steep shoaling soliton shape has strong surface pressure variations, potentially inducing overturning shape changes. Through wave-overturning impacts on turbulence and sediment suspension, coastal wind variations could be relevant for near-shore morphology.
