The total number of trips made to Ireland by overseas residents increased by 12.4% to 575,300 in February, new figures from the Central Statistics Office show.
The CSO said that trips by UK residents increased by 13.1% to 263,500 in February of this year compared to the same month last year.
Trips by residents of European Countries apart from the UK rose by 18.3% to 202,100, while trips by residents of the US and Canada were up 5.4% to 79,600.
The CSO also noted that trips to Ireland from other areas of the world fell by 8% to 30,100.
During the first two months of this year, the total number of trips to Ireland increased by 7.9% when compared with the same time in 2017.
Meanwhile, the total number of overseas trips made by Irish residents in February 2018 decreased by 2.9% to 492,400.
Tourism Ireland noted that arrivals from Britain are up 4% for the first two months of 2018, but it noted that this does not represent a turnaround in the long-term trend.
"The impact of Brexit on outbound travel from Britain, remains a concern. The fall in the value of sterling has made holidays and short breaks here more expensive for British visitors and has made Britain more affordable for visitors from many of our top markets," commented Niall Gibbons, CEO of Tourism Ireland.
Mr Gibbons said that competitiveness and value for money remain more important than ever in Britain this year.
He also said that the air and sea access picture is very positive for the summer months, with increases in the number of airline seats from Britain, Mainland Europe, North American and long-haul markets.
"We particularly look forward to seeing the impact of new long-haul flights on Irish tourism this summer - including the Hainan Airlines flight from Beijing and the Cathay Pacific flight from Hong Kong, both due to begin in June," Mr Gibbons said.
"In terms of ferry services, there will be an almost doubling of the number of sailings and capacity between Mainland Europe and Ireland this year," he added.
