Almost half of TT race reschedulings over the past decade have happened in the last two years, according to figures from the Department for Enterprise.
A Freedom of information request asked about races which had to be called off completely or moved because of weather.
Since 2016, 22 races had to be rescheduled - four this year, six last year, seven in 2019 and four in 2017.
Meanwhile, just three races have been scrapped altogether over the same period, with one in each of the past two years and one in 2017.
