The CSO has released the figures.
There was a 59 per cent increase in the number of overseas visitors to Ireland in August compared to July.
362,600 people travelled here, according to figures from the CSO.
That compares to 227,300 people the previous month.
There was a twenty per cent increase in the numbers of passengers departing Ireland in August.
However, the Central Statistics Office say the figures are a small fraction of the numbers that travelled in the same month last year.
In 2019, two million people arrived and departed in August.
Speaking about the recent figures, statistician Gregg Patrick said:
“The Air and Sea Travel Statistics for August 2020 show a very substantial increase in overseas travel compared to the preceding month. In August, 362,600 overseas passengers arrived in Ireland, compared to 227,300 in July, an increase of 59.5 per cent.
"The August 2020 statistics show that continental routes contributed most to the passenger traffic. Some 228,700 passengers arrived on continental routes and 186,000 passengers departed on continental routes."
