Machynlleth has a cool, wet oceanic climate. Winds often come from the southwest across the Atlantic Ocean. These winds bring moist air, clouds, and rain. Atlantic low-pressure systems can cause windy, unsettled weather, especially from autumn to spring. High-pressure systems may bring calmer, drier days.
The town lies near the Dyfi Valley and the Cambrian Mountains. Hills force moist air to rise, which can increase rainfall around Machynlleth. The nearby coast helps keep temperatures from becoming very hot or very cold. Valleys can also hold mist and cloud, especially on calm mornings.
Summers are usually mild, with some sunny days and regular showers. Winters are cool and often wet, windy, and cloudy. Snow can fall during colder weather, mainly on higher ground, but it is less common in the town. Spring and autumn often bring quick changes between sunshine, rain, and strong winds.
