In this research, water sample was collected from Kwalkwalawa river, in Kwalkwalawa village, Sokoto State, North Western Nigeria. 25L of the water samlpe was used to fill a sinlge slope solar still, and the whole set up exposed to the solar energy. The distillate yields of the sample were recorded at one hour intervals between the hours of 8.00am and 18.00pm. The corresponding values were measured for some meteorological variables like: solar radiation, ambient temperature, relative humidity and wind speed during each inerval. The results were tabulated and picturesque using bar charts. It was oberved that the maximum yield recorded was obtained by 15.00pm. which also corresponds to the highiest value of wind speed which accounts for condensation of the evaporated distillate. The relative humidity varied inversely with the yield. It has been observed that solar radiation varies parabolically with time, with its maximum value at 13.00pm. Solar radiation also varies linearly with yield only that, radiation reached its peak at around 13.00pm while the yield reached its maximum value around 15.00pm. Finally the yield of the distilled water incresed as the ambient temperature increased, with the maximum yield recorded at the maximum value of the ambient temperature ie at 15.00pm. When the ambient temperature started to decline, the yield also started to decline equally.
