If you think about Ireland, the first thing that comes to mind is rain, drizzle, cold and wind. Although it is true, sometimes, during the summer months, the sun appears also in the Emerald Island (and in June and July it shines until 10 PM!)
When you are visiting Dublin in summer, it's great to get away from the grayish capital to the beautiful coastal areas, especially because they are so close and at the price of only 5 EUR (7 USD) for a return ticket, using public transport, you can admire the beautiful nature that surrounds the city. You will be surprised.
