In common with most of the rest of the United Kingdom, Chester has an "oceanic" climate. Despite its proximity to the Irish Sea, the temperature regime is similar to areas further inland, owing to the shelter provided by the Pennines to the northeast and the Welsh Mountains to the southwest. The nearest official weather station is at Hawarden Airport, about 4 miles (6.4 km) west of the city centre. Average annual rainfall is barely over 700mm due to a "rain shadow" effect caused by the Welsh Mountains.
