Let μ be a measure from Szegő class on the unit circle T and let {f n} be the family of Schur functions generated by μ. In this paper, we prove a version of the classical Szegő's formula, which controls the oscillation of f n on T for all n⩾ 0. Then, we focus on an analog of Lusin's conjecture for polynomials {φ n} orthogonal with respect to measure μ and prove that pointwise convergence of {| φ n|} almost everywhere on T is equivalent to a certain condition on zeroes of φ n.
