In this note we prove that for equilibrium states of axiom A systems the time
$\tau_{B}(x)$ needed for a typical point $x$ to enter for the first time in a
typical ball $B$ with radius $r$ scales as $\tau_{B}(x)\sim r^{d}$ where $d$ is
the local dimension of the invariant measure at the center of the ball. A
similar relation is proved for a full measure set of interval excanges. Some
applications to Birkoff averages of unbounded (and not $L^{1}$) functions are
shown.
