Forecast

Porthmadog has changeable weather. When it's stormy, air pressure drops; when it's calm, pressure rises. The town's coastal location and nearby mountains affect air pressure. Air is forced to rise over mountains, cooling and creating rain; this lowers air pressure. In winter, low-pressure systems bring rain; in summer, high pressure brings sunshine. Porthmadog has a maritime climate, with mild temperatures and changing pressure. The Atlantic Ocean influences the climate, bringing wet and windy weather. Winds from the ocean can bring low-pressure systems. High-pressure systems sometimes bring clear skies. The town experiences a mix of sunny and rainy days. Rainfall occurs throughout the year. Snowfall is rare but possible in winter. Pressure changes affect the weather greatly.
