Highlights of the Summer In Dublin programme include a Viking festival at Wood Quay, the street performance world championships in Merrion Square, lunchtime outdoor concerts and the reopening of the Natural History Museum.
Tom Coffey, of Dublin City Business Association, said more people are holidaying at home this year due to the uncertainty created by the Icelandic volcano and various airline disputes.
"Many are expected to visit the capital as their 'staycation' destination of choice," said Mr Coffey.
"Only last week Dublin was ranked as a better city to live in than Paris or London, according to the Mercer Worldwide Quality of Life Survey.
"Dublin City Centre combines a unique ambience with beautiful architecture, amusing characters and world class amenities in a truly original way."
Dublin City Council expects some 500,000 people to attend events such as a national play day and kings of concrete.
"We are anticipating a fine summer in Dublin," added Michael Sands, communications manager.
"Combining this with the wonderful programme of events on offer, we are anticipating that increased numbers of people will come into Dublin City and enjoy the wide variety of activities."
