We report results of a muon spin rotation ($\ensuremath{\mu}\mathrm{SR}$) study of the cuprate-analog nickelate ${\mathrm{La}}_{4}{\mathrm{Ni}}_{3}{\mathrm{O}}_{8}$, which undergoes a transition at 105 K to a low-temperature phase with charge-stripe and antiferromagnetic (AFM) order on square planar ${\mathrm{NiO}}_{2}$ layers. Zero-field $\ensuremath{\mu}\mathrm{SR}$ shows that the AFM transition is abrupt, commensurate, and has a quasi-two-dimensional character below $\ensuremath{\sim}25$ K. Comparison of observed muon precession frequencies with Ni dipolar field calculations yields Ni moments $\ensuremath{\lesssim}0.5\phantom{\rule{0.16em}{0ex}}{\ensuremath{\mu}}_{B}$. Dynamic muon spin relaxation above 105 K suggests critical slowing of Ni spin fluctuations, but is inconsistent with corresponding $^{139}\mathrm{La}$ NMR results. Critical slowing and an abrupt transition are also observed in the planar cuprate AFM ${\mathrm{La}}_{2}{\mathrm{CuO}}_{4+\ensuremath{\delta}}$, where they are taken as evidence for weakly interplanar-coupled two-dimensional AFM spin fluctuations, but our $\ensuremath{\mu}\mathrm{SR}$ data do not agree quantitatively with theoretical predictions for this scenario when applied to the nickelate.
