Ireland enjoys a temperate maritime climate, so you can expect mild temperatures, especially in September. The island is predominately influenced by the Atlantic Ocean. As a result, it does not have the extreme temperatures than other countries of similar latitude would have. A major warm ocean current called the North Atlantic Drift keeps sea temperatures in Ireland mild too. The hills and mountains that surround Ireland’s coast also provide shelter to the rest of the island from strong winds coming off the ocean.

September weather is generally the same throughout the island, but it is good to keep in mind that there are slight regional variations in Ireland.

What to pack for Ireland in September
With Ireland’s changeable weather packing for your September visit may not seem like the easiest task. When it comes to Irish weather, you need to be adaptable and layering is key. Make sure to pack a variety of clothing to ensure you will be comfortable no matter what.
Pack layers! The trick to staying warm is to have many layers that you can put on and take off to adjust the temperature. Whether the sun is in or out you can put on or take off your layers as the weather changes. A light raincoat and a scarf are advised. Try and opt for a raincoat which can be rolled up when not required.
Layers are also ideal when trekking around the cities or rural areas of Ireland. Cold, windy weather can require additional clothing, but the more you're active, the more you can remove you outwear.
The wet weather does not mean you cannot experience the outdoor activities, such as hiking, golfing or visiting the grounds of one of Ireland's historic castles. However, it does call for making sure you are well prepared with the gear needed to enjoy a rain-swept Ireland.
Make sure to have items that block wind and protect against the September rain! Be sure to leave extra room in your suitcase for good walking shoes and an umbrella.
