Average sea level air pressure is 39.37 inches of mercury (100 cm. or 1 meter of mercury), so 30.49 inches is low. Any thing over 39.37 (adjusted for the local distance above sea level) is thus high. We use inches or centimeters of mercury to measure air pressure because, if a long glass test tube is filled with mercury and then turned upside down in a pot of mercury, the weight of the mercury in the tube will create a vacuum in the upper end of the tube. The height of mercury in the tube, measured from the surface of the pot of mercury will depend on the amount of air pressure pushing on the surface of the mercury in the pot. At average sea level pressure, that distance will be one meter, or 39.37 inches.
