  Primordial Black Holes (PBHs) are remnants of objects formed in the early
Universe. Their lifetime is an increasing function of their mass, so PBHs in
the right mass range can end their lives in an evaporation event that is
potentially detectable by our instruments now. This evaporation may result in a
$\gamma$-ray flash that can be detected by the current generation of
Very-High-Energy $\gamma$-ray detectors. The Southern Wide field of view
Gamma-ray Observatory (SWGO) will be part of the next generation of these
instruments. It will be able to establish limits on PBH evaporations for
integration windows between 0.5 and 5 s, in a radius of 0.25 pc around the
Earth, being sensitive to a rate of the order of $\sim$50 pc$^{-3}$ yr$^{-1}$,
more than one order of magnitude more constraining than the currently
established best limits.
