Footage taken on Friday shows motorists, caravans, and camper vans, hitting the M5 this lunchtime heading south through Gloucestershire towards Devon and Cornwall.
With temperatures predicted to hit the mid-20s over the May Bank Holiday weekend, and Covid restrictions limiting foreign travel, holidaymakers have made the most of the good weather and targeted British resorts.
Footage was taken from an overpass near Junction 11.
The Sky forecast for Saturday suggests that "although there'll be cloud around, there'll also be bright or sunny spells.
"Temperatures will reach the high teens in the north, but the low 20s Celsius through southern parts."
Into Sunday, the forecast says: "Sunday will potentially be the best day of the long weekend, with fewer showers and more in the way of sunshine.
"More locations will see the mercury rise above 20 Celsius with the maximum value approaching 24 Celsius, 75 Fahrenheit.
"Cloud and rain will try to push into the north-west on Monday giving more overcast conditions for Scotland and Northern Ireland.
"England, Wales and eastern Scotland will be dry with sunny spells."
BBC Meteorologist Tomasz Schafernaker tweeted: "You won’t believe this…but we’re increasingly confident that the weather will FINALLY be settling down end of this week and into the weekend!"
