My current car has temp sensors exterior and interior . When I lived in Altona , a bayside Melbourne suburb , it would show , for instance 26c . When I head up to where I live now , Altona Meadows , less than 10 minutes away inland , the temp gauge can go as high as 30c outside temp . I hate the heat so it is costing me , as stated in previous posts , more power for aircon etc . /
Strangely though I often head over to Williamstown , another bayside suburb and it can be 30c where I now live 25c where I used to live , Altona and 31c in Williamstown which is on a peninsula with the bay surrounding it . Hmmm strange .
