The Lite's figure is at its lowest since October 2006, two months after its launch.
The street distribution of the papers may have been affected by the high number of rainy days in June.
The Evening Standard was ready to use the rain as an excuse, but it still increased its circulation by 0.98% on May to 276,230.
The Standard's full rate sales were 198,601. A spokeswoman said: "Despite it being the wettest month this century, the month on month, full rate sales trend between May and June is the best for five years. The average seasonal decline over the last four years was 6.8%. In June it was 2.5%, and rain would normally dramatically adversely affect ES sales."
However, the Standard's six-month average circulation is still down 16.99% year-on-year to 270,718.
Morning freesheet Metro distributed 547,027 copies in London in June, a decrease of 0.19% from May. Its six-month average is up 3.5% year-on-year to 546,710.
Its national distribution fell 0.38% on May to 1,122,052 in June but its six-month average is up 7.66% to 1,122,923.
City AM stayed over the 100,000 mark for the third month in a row, slipping 0.18% on May to 100,486. Its six-month average is up 25.31% year-on-year to 96,681.
Reports last month claimed Metro will increase its London distribution by 250,000 copies from September.
Jens Torpe, chief executive of City AM, said: "We're now seeing the city wind down for the summer break and we're lowering our distribution accordingly for the months of July and August. Our circulation growth will pick up again in September to deliver over 100,000 again."
