A radiation inversion may form at night and could cause wind shear but it will not be present in the afternoon.   A subsidence inversion forms in anti-cyclones at altitude and will not cause wind shear near the surface.   A land breeze may be present at night but not during the afternoon.   A sea breeze could be present and the wind direction would reverse between 600 – 800 ft agl and the surface which may cause wind shear on the approach and the surface wind will be more or less perpendicular to the runway.
