M25 Traffic Trends
Which hour is slowest on the M25 on a Monday morning, and which quarter of the loop holds up first on a Friday evening? These pages answer that from our own record of National Highways' live speed data: we read the speed on every stretch of the M25 every five minutes and keep the average for each hour, clockwise and anticlockwise.
Choose a day of the week below to see how the motorway moved on the most recent one, against the same day a week earlier and the speed National Highways normally expects. For the road right now, use the live M25 traffic flow map and the latest M25 traffic news.
Pick a day to see how traffic on the M25 moved hour by hour, compared with the same day a week earlier. Each page updates regularly.
Speeds are colour-coded the same way as our live M25 speed flow map: 50 mph and over, 30 mph to 49 mph, under 30 mph. The colour shows the speed actually achieved; the usual speed is shown in bold beside it.
