While Carlow is often marketed as being part of the ""Sunny Southeast"" alongside Wexford and Waterford, due to its inland location it does not typically benefit from the elevated sunshine hours observed in the coastal areas of those counties. However, it does experience significantly higher average temperatures and lighter winds during the summer months due to its sheltered location. This was exemplified during the 2018 summer heat wave, when Oak Park was both the hottest and driest location in Ireland.
