An exposure apparatus illuminates a pattern with an energy beam and transfers the pattern onto a substrate via a projection optical system. The exposure apparatus includes a substrate stage on which the substrate is mounted that moves within a two-dimensional plane holding the substrate. The apparatus also includes a supply mechanism that supplies liquid to a predetermined spatial area which includes a space between the projection optical system and the substrate on the substrate stage, and an adjustment unit that adjusts exposure conditions based on temperature information on the liquid between the projection optical system and the substrate.
