This represented a significant outperformance of the wider Scottish hotel sector, which recorded a 4.3% year-on-year rise in revenue in June, a survey by accountancy firm BDO showed.
Aberdeen recorded a 19% year-on-year rise in revenue. Edinburgh and Inverness posted respective falls of 1.5% and 5.8%.
The hotel sector in Scotland put in a stronger showing than other parts of the UK in June. The BDO survey, which includes a broad range of three and four-star properties, showed the UK hotel sector, excluding London, recorded a 2.8% year-on-year rise in revenue in June.
Rooms yield, or revenue per available room, in the Scottish hotel sector came in at £63.93 in June, up from £61.30 in the same month of last year. This rooms yield figure is calculated by multiplying occupancy by the average room rate achieved.
For the wider UK hotel sector, outside London, the rooms yield figure for June was £48.80.
In Glasgow, revenue per available room came in at £54.96 in June, up from £49.25 in the same month of last year.
BDO said: "Glasgow experienced a considerable 11.6% boost to revenue through its successful concert and events promotions, including the Neil Young concert in the city."
The Glasgow hotel sector's occupancy rate, the ratio of occupied rooms to available rooms, came in at 83.7% in June. This was up from 82.7% in June 2012.
Revenue for the Aberdeen hotel sector came in at £73.12 in June, up from £61.43 in the same month of last year. BDO said that this rise in revenue in the Aberdeen hotel sector was attributable, in part, to the city's hosting of the PIPER25 conference.
This offshore safety conference, held by industry organisation Oil & Gas UK at the Aberdeen Exhibition and Conference Centre from June 18 to 20, marked the 25th anniversary of the Piper Alpha disaster. It aimed to bring together people from across the oil and gas industry to reflect on the lessons learned from the tragedy, review how far offshore safety had evolved since, and reinforce industry commitment to continuous improvement.
In the Edinburgh hotel sector, revenue per available room came in at £77.67 in June, down from £78.85 in the same month of 2012.
However, BDO noted occupancy in Edinburgh was nevertheless strong, at 85% in June. Occupancy for the wider Scottish hotel sector came in at 81% in June, down marginally from 81.3% in the same month of last year. The Scottish occupancy rate was well ahead of the corresponding figure of 76.9% for the wider UK hotel sector, outside London, in June.
Alastair Rae, a BDO partner who covers the property, leisure and hospitality sector, said: "The continued improvement in revenue among Scottish hotels appears to indicate that this is turning out to be a better season for the sector.
"Despite a slight revenue fall in Edinburgh and a larger decline in Inverness, the overall figure for Scotland of £63.93 is substantially higher than the rest of the UK. Whilst one month's data will not indicate a trend, we have now had Scottish occupancy and revenue figures ahead of the UK every month this year since March."
