Footfall in June was 0.1% higher than a year ago, up from a 0.7% decline in May according to the latest BRC/Springboard Footfall Monitor.
Footfall increases above the UK average were reported both on the high street (1.4%) and out-of-town locations (0.6%).
The footfall trend in shopping centre locations remained in negative territory, falling 3.0% from a 1.7% decline in May.
Greater London (2.4%), Wales (2.3%), the West Midlands (1.3%) and Scotland (1.2%) all reported a rise in footfall above the UK average.
In the first six months of 2013, footfall fell on average 1.5% compared with a 2.9% decline during the same period in 2012.
Helen Dickinson, British Retail Consortium Director General, said: "The UK High Street was busier in June, and BRC figures show that footfall has increased as we have seen shoppers take advantage of the good promotions available at the moment in stores. The relatively strong UK wide figures are reflected in modest increases in footfall in out-of-town retail, although shopping centres did not perform quite so well."
"The improvement in the weather may well have contributed to this. Our recent retail sales figures showed a strong performance from fashion and footwear and it is likely that shoppers took advantage of the start of the sunshine in June to visit their local high street and buy items for their summer wardrobes."
"As we have seen in recent months, the increase in footfall was not universal across the country. BRC figures continue to show regional and national variations. London and the West Midlands saw the best performances in England. In Wales and Scotland, the High Street also had a good month."
