Does it rain a lot in Snowdonia?
With over 3000mm (3 meters) and 200 days of rain annually, Snowdonia National Park is the wettest place in Wales.
Why does it rain a lot in Snowdonia?
The National Park is a hyper-oceanic climate which usually experiences maritime air masses. These air masses accumulate moisture as they cross the Atlantic Ocean forming clouds.
When these air masses make landfall, they often deposit this moisture in the form of rain. This is exaggerated in mountainous regions such as the Lake District and Snowdonia.
As the air rises over the mountains, it cools due to decreased air pressure at higher elevations. Thinner air is less able to retain heat, so there is less evaporation increasing the moisture levels. This causes the water droplets in the clouds to grow, eventually becoming too heavy to be supported by the clouds. When this happens, it rains.
This process is why Snowdonia is the wettest place in Wales and why it is even wetter on mountain summits.
