How normal is the weather forecast air pressure?

10 13.25 HPA. According to the weather station information, the normal atmospheric pressure in weather is 10 13.25 hectopascals, that is, 1 standard atmospheric pressure. This refers to the pressure at sea level. However, with the increase of altitude, the air pressure value will gradually decrease. For example, at an altitude of 1000 meters, the air pressure is only 900 hectopascals.
