Researchers from the Centre for Advanced Spatial Analysis (CASA) at University College London monitored all geo-located tweets sent from smartphones in the UK.
The study analysed more than 1.3 million tweets, taken from August 28 to September 4.
Researchers found that spikes in swearing came on Saturday and Sunday afternoons during football matches, 'BBC News' reported.
On weekdays, tweets with swear words were found to be more concentrated in the mornings - when people were getting ready for work - at lunchtime and at the end of the working day.
The findings also showed Redcar and Cleveland to be UK's most profane area while Oxford and Westminster were among the least coarse.
