Abstract: In this note we introduce a dyadic one-sided maximal function defined as

\begin{displaymath}M^{+,d}f(x)=\sup_{Q\;dyadic\text{:}x\in Q}\frac{1}{\left\vert Q\right\vert } \int_{Q^{+}}\left\vert f\right\vert ,\end{displaymath}

where $Q^{+}$ is a certain cube associated with the dyadic cube $Q$ and $f\in L_{loc}^{1}\left( \mathbb{R} ^{n}\right) $. We characterize the pair of weights $\left( w,v\right) $ for which the maximal operator $M^{+,d}$ applies $L^{p}\left( v\right) $ into weak- $ L^{p}\left( w\right) $ for $1\leq p<\infty $.
