Forecast

The barometric pressure in Greymouth is influenced by its coastal location. It can fluctuate rapidly due to the proximity of the Tasman Sea. This leads to changing weather patterns.

Greymouth is situated in a valley surrounded by mountains. The Southern Alps are to the east and the Tasman Sea is to the west. This unique landscape creates a channeling effect. Air masses from the sea are pushed upwards, resulting in rising air and cooling temperatures.

As the air rises, it cools and condenses, forming clouds and precipitation. This process contributes to Greymouth's high rainfall. The surrounding mountains also block or redirect winds, further influencing the local weather.
