Upon considering 0.2% shop price deflation, the total sales of the month rose by 3%.
The report has further revealed a marginal increase of 0.3% in like-for-like sales, when compared to the same in June 2012.
Driven by food and non-food sales, total sales year-to-date grew 1.1% compared to 0.5% average of 12-month period.
Sales from food recorded 4% increase compared to 3% growth in June 2012.
Non-food sales, driven by clothing and footwear, registered an increase of 1.8%, against 0.5% drop in the previous year.
The overall sales growth is in line with retail growth the UK, stated SRC.
SRC director Fiona Moriarty said warmer weather and a steady rise in consumer confidence are primarily behind the encouraging growth.
"Food was the stand-out performer in a month where all categories posted good results," Moriarty added.
"Non-food also saw a major improvement, reflecting that Scottish shoppers are still responding well to targeted promotions, whilst also catching up on updating their wardrobes for summer after putting off purchases during the prolonged cold snap in Spring.
"Retailers’ spirits will be buoyed by this strong showing which is well above the annual and six-month averages and chimes with the decent footfall growth we saw earlier this week."
