What should I pack for Ireland in September?

September is the beginning of the Fall season in Ireland and layering is yet again another trick you can master. In general, September is still a pleasant-month in Ireland with a mixture of sunshine and rain shower but it’s not that warm neither.

Hoodie – You can also wear a hoodie on top of your innerwear. Hooded jackets can also shield you from light showers. Amazon is selling this pullover hoodie. Check it out here.

Jeans – Pack lots (or enough pair) of jeans most especially if you are easily cold and since there will be chances of rain, you definitely don’t want to repeat wet jeans, right?

Wool blazer – If you don’t want to be too casual, you can opt for a wool blazer like this one. You can go for a slim-fit type or the oversized type. What’s good about it is that you can easily layer it on top of your blouse or shirt while keeping a smart-casual look.

Boots – In case of heavy or constant rainfall, pack sturdy boots to keep you comfortable walking around. This signature Timberland boot is a perfect addition to your Fall packing list.

Fleece sweater – When the temperature begins to drop again, a fleece sweater should always be in your list. Its material will keep you warm– sometimes enough to be worn alone or you can wear it underneath your preferred outerwear.

Umbrella – Don’t forget to include an umbrella in your packing list to shield you from the rain. This compact travel umbrella from Amazon is a good option as it will easily fit in your luggage or in your everyday bag.
