This is a 61 per cent increase over the same period in 2022 and the highest total on this route for this period since 2016.
However, the number of monthly detections in the Central Mediterranean to Italy dropped 24 per cent month-on-month in November to nearly 7900, the agency added.
The decrease was in line with arrivals on all other routes.
On the Central Mediterranean route, the top three countries of origin so far this year have been Guinea, Tunisia and Ivory Coast.
In the first 11 months of 2023, 355,300 irregular migrants arrived in the European Union, up 17 per cent over the same period in 2022 and the highest figure recorded since 2016, Frontex said.
The biggest rise has been seen on the Western African route to the Canary Islands, where arrivals more than doubled to reach 32,422.
The top three countries of origin across all routes so far this year have been Syria, Guinea and Afghanistan.
