MORE than 2,000 complaints about noisy neighbours were reported across Wales at the height of the heat wave.
As the country baked in temperatures that were hotter than Spain and a record for July of 34.2C was measured at Penhow near Newport, tempers boiled over between normally civil neighbours.
Noise control officers received 2,189 complaints in July, compared to around 1,500 in the same month last year, according to our snapshot of figures from most of the 22 local authorities of Wales.
Officers said doors and windows were flung open by residents who also pumped up the volume at garden parties and barbecues.
Some householders took advantage of the dry, light nights to concentrate on DIY improvements, with drills and cement mixers on the go, impacting on their neighbours' enjoyment of some quiet time in the sunlight.
Complaints increased most dramatically of all in Cardiff.
The capital saw a three-fold increase in the number of complaints received - 531 were reported last month, compared to 176 in 2005. In Swansea complaints were up by 26%.
Julie Barratt, director of Chartered Institute of Environmental Health, Wales, said the hot weather makes us hot tempered too and we are more likely to complain.
She said, "Whenever the weather is hot, the things that would normally just irritate us, like hearing your neighbours playing loud music, can drive us mental.
"When we are hot, tired and tetchy, we are far more likely to ring up and complain.
"The World Cup was on and people were in big groups drinking in the streets and beer gardens too.
"That is fine if you are one of the people enjoying it, but if you are sitting at home and you have to shut your windows and turn up the television just to hear it, things can play on your mind.
"You might think you are going to have things thrown in your garden or there is going to be some sort of trouble, whether there is or not. We are not lifestyle police but we think people should be able to live normally."
She said Cardiff and Swansea were the main noise offenders mainly because people live closer together there.
She said, "Cardiff is a 24-hour city where you can stay up and party all night if you want to, but the problem is that it often clashes with the nine-to-five workers."
Councillor Brian Griffiths, chair of Cardiff's public protection committee, added, "Noise affects the quality of life of everyone and the council is encouraging people to consider the noise that affects them and the noise that they make.
"Simple measures can be taken to prevent problems and it is important that householders and businesses consider the noise they make and how they can prevent unnecessary disturbance."
A Caerphilly County Borough Council spokeswoman said a rise in anti-social behaviour was even worse.
She said, "The number of complaints for domestic-type noise in Caerphilly County Borough doubled last month compared to July 2005. Many of these complaints were related to obscene music and drunken behaviour.
"The anti-social behaviour aspect of noise complaints to the authority has become a major concern. There were many more reports of abusive behaviour associated with parties, barbecues and music from cars parked in the street this summer."
