A record number of migrants flowed into the Big Apple last week — with city officials logging nearly double the daily average of asylum seekers, new data shows.

Roughly 3,900 migrants arrived in New York City over the seven-day span ending Sunday, according to City Hall data.

That brings the total number of asylum seekers who have made their way to the Big Apple to more than 126,700 since the start of the crisis in spring 2022.

More than 64,100 of those migrants still remain in the city’s care, according to City Hall.

The old record was set last week, as about 3,700 new asylum seekers arrived in the Big Apple. That was a few hundred more than the weekly average, which has hovered around 3,000 over the last few months.

The average of new asylum seekers has recently come in at 300 to 400 per day while over recent weeks that has grown to nearly 600.

The uptick had been expected over the last few weeks with the number of migrants arriving at the border increasing recently.

City officials were scrambling behind the scenes last week to identify new shelter spots ahead of the surge of asylum seekers heading for the Big Apple.

The weekly tally though came in under the expected estimates of 4,200 to 5,600 per week.

Deputy Mayor Anne Williams-Isom said last week she was already “concerned” with the increase in asylum seekers in recent days.

“I can’t believe that we’re still in this situation where we are talking about how many more sites we want to open,” she said during the mayor’s off-topic briefing on Oct. 3.

The deputy mayor’s comments came a day before Mayor Adams jetted to Central and South America as part of a fact-finding mission to learn about the path of migrants to the US and try to dissuade people from coming to New York.
