The weather in Portishead is affected by its proximity to the Atlantic Ocean, which brings low-pressure systems that reduce barometric pressure. These systems also bring wind and rain.
Portishead's elevation near the coast and its hilly landscape cause air to rise, cool, and condense, leading to changes in atmospheric pressure. This can create local pressure differences.
In summer, high pressure dominates, leading to calm and sunny weather. In winter, low pressure brings wind, rain, and storms. Spring and autumn see a mix of both.
Portishead has a maritime climate, which means it has mild temperatures and high rainfall. This leads to frequent changes in barometric pressure, causing varying weather conditions throughout the year.
