The BRC-Sensormatic footfall monitor showed that total footfall declined 3.4% on the year following a 2.6% drop in May.
Footfall on high streets was down 6.2% in June following a 1.5% decline the month before, while retail parks saw a 0.3% dip following a 0.5% fall in May.
Footfall at shopping centres was 2.5% lower in June, having dropped 2.4% the month before.
Footfall rose 1.7% in Scotland, but fell 0.9% in Northern Ireland, 2.3% in Wales, and 3.0% in England.
BRC chief executive Helen Dickinson said: "Footfall dropped in June as the record heatwave kept many shoppers indoors. High streets saw the sharpest declines, while air-conditioned shopping centres and retail parks proved more resilient. While London and the South East - where temperatures were highest - registered the biggest decline, other regions performed markedly better. Scotland saw footfall rise, buoyed by cooler weather and the continued gradual opening of Glasgow City Centre after March’s devastating Union Corner fire.
"The heatwave may have affected footfall, but retailers face a bigger challenge: rising costs. Businesses are working hard to deliver value for customers, yet higher taxes and regulatory burdens are making it harder to invest, create jobs and grow. Government action on business rates and energy costs would help unlock investment to revive our local communities."
