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 $\theta_{avg} = 45^{\circ}$. I know this is late but the method of decomposing the directions into u and v components is correct, although the best thing would be to work with complex numbers, since it is way simpler (automatic, actually). interval [0, 360)) is to calculate the mean of the cosines and sines Perth weather by month.
