Perth's hottest night since records began was one of 156 weather records broken over a 90-day period during what the Climate Council has dubbed a second "angry summer".

The council's 2013-2014 Angry Summer report, released by the council on Monday, highlighted the continuing trend of hotter summers and more weather extremes in Australia.

During the 90 summer days, Perth recorded its hottest summer night of 29.7 degrees on January 12 and registered its joint second hottest summer on record with eight of Australia's hottest summers on record occurring in the past 15 years.

According to the report, since 1950 the number of heatwave days each year had increased in Perth, Adelaide, Melbourne, Sydney, Canberra and Hobart and across Australia as a whole.

Professor Tim Flannery said the report showed the country was already experiencing heat extremes related to climate change.
