Poor sound occasionally in summer on hot days

Your earlier thread on the topic:

Poor sound quality in hot summer days

Does anyone else notice that on hot summer days with fans and air conditioners going on all around the neighbourhood that the sound quality is not as good as on medium days? I find that my sound is best early Saturday and Sunday and on mild but not too hot days. Even though I have a power conditioner and a Hydra power distributor the sound seems to be deteriorated during peak work day hours and in the heat. My best sound is when it is rainy outside somehow. Does anyone else experience this?
