  abstract = {{E}xtreme climate events, either being linked to dry spells or extreme precipitation, are of major concern in {A}frica, a region in which the economy and population are highly vulnerable to climate hazards. {H}owever, recent trends in climate events are not often documented in this poorly surveyed continent. {T}his study makes use of a large set of daily rain gauge data covering {S}outhern {W}est {A}frica (extending from 10 degrees {W} to 10 degrees {E} and from 4 degrees {N} to 12 degrees {N}) from 1950 to 2014. {T}he evolution of the number and the intensity of daily rainfall events, especially the most extremes, were analyzed at the annual and seasonal scales. {D}uring the first rainy season ({A}pril-{J}uly), mean annual rainfall is observed to have a minor trend due to less frequent but more intense rainfall mainly along the coast of {S}outhern {W}est {A}frica ({SWA}) over the last two decades. {T}he north-south seasonal changes exhibit an increase in mean annual rainfall over the last decade during the second rainy season ({S}eptember-{N}ovember) linked by both an increase in the frequency of occurrence of rainy days as well as an increase in the mean intensity and extreme events over the last decade. {T}he study also provides evidence of a disparity that exists between the west and east of {SWA}, with the east recording a stronger increase in the mean intensity of wet days and extreme rainfall during the second rainy season ({S}eptember-{N}ovember).},
