  An isogeny class $\mathcal{A}$ of abelian varieties defined over finite
fields is said to be "cyclic" if every variety in $\mathcal{A}$ has a cyclic
group of rational points. In this paper we study the local cyclicity of
Weil-central isogeny classes of abelian varieties, i.e. those with Weil
polynomials of the form $f_\mathcal{A}(t)=t^{2g}+at^g+q^g$, as well as the
local growth of the groups of rational points of the varieties in $\mathcal{A}$
after finite field extensions. We exploit the criterion: an isogeny class
$\mathcal{A}$ with Weil polynomial $f$ is cyclic if and only if $f'(1)$ is
coprime with $f(1)$ divided by its radical.
