The latest official count has found 142 rough sleepers on the streets of Dublin.
The figure shows an increase of 56% over the past year in the numbers of homeless men and women who are unable to get into emergency accommodation.
The count was carried out by the Dublin Region Homeless Executive on 22 November and compiled the rough sleepers throughout the four Dublin local authority areas.
The figures do not include an additional 77 people that were sleeping on the floor of Merchants Quay Ireland night cafe that night.
The executive has announced details of plans to cope with the surge in homelessness with 230 emergency places to become available between now and 9 December.
Most will be in the northwest inner city area of Dublin 7 with 70 beds run by the Peter McVerry Trust on Ellis Quay, 75 beds with Depaul Ireland on Little Britain Street and 20 beds run by the Civil Defence on Wolfe Tone Quay.
Another 65 beds will be operated by Dublin Simon and the Salvation Army at Carman's Hall Community Centre in Dublin 8.
Chief Executive of the Peter McVerry Trust Pat Doyle said the figures were not "unexpected but nevertheless they are deeply disappointing and very frustrating".
He continued: "Peter McVerry Trust's view is that the only effective way that we can begin to reduce and ultimately eliminate rough sleeping is to ensure we have enough appropriate housing options.
"To that end we need to see stronger and quicker interventions to make housing available."
The Peter McVerry Trust called for the introduction of a vacant property tax to push some of the 35,000 vacant homes in Dublin back into the system while Focus Ireland called on the Government to ensure that tenants are not evicted when buy-to-let properties are repossessed.
Dublin Simon Community has said the figures are the minimum and that their teams have recorded a figure of 162 rough sleepers in Dublin city centre alone.
While the figures are an increase on last year they do not match the previous highest number of 168 recorded in November 2014.
In general, numbers have been increasing steadily in recent years from just 60 rough sleepers recorded in 2009.
The biggest jump occurred between 2012 and 2013 when the numbers went from 87 to 139.
