The figure below presents a compact representation of key lunar data for 2023. In the case where your wind always has the same speed (or at least can be assumed to have constant speed), this is better than the mechanism you suggest: for instance, in your method an east wind ($\theta_0=0^{\circ}$) and a north wind ($\theta_1=90^{\circ}$) will give $s_0 = \sin(0^{\circ}) = 0$ and $s_1 = \sin(90^{\circ}) = 1$, so $s_{avg} = 0.5$ and $\theta_{avg} = \sin^{-1}(s_{avg}) = 30^{\circ}$, whereas the average-of-vectors method yields $v_0 = (\cos(\theta_0),\sin(\theta_0)) = (1,0), v_1 = (0,1), v_{avg} = (0.5, 0.5)$ and $\theta_{avg} = 45^{\circ}$.

The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands. Shortwave radiation includes visible light and ultraviolet radiation.
