It might be because I avoid going to Dumaguete during the day. It's quite pleasant during the day here in Valencia. A ceiling fan is all that's needed for me. I don't think I could stand to live in Dumaguete due to all the extra heat that the city puts off (I believe the temperature you see online is actually measured at the airport.....which isn't even Dumaguete). You can really feel it at night when driving up to Valencia even while still within the Dumaguete city limits. A couple hundred meters past Hypermart you can feel about a 5 degrees (fahrenheit) drop in the temperature as you are leaving the town. There is usually another noticeable temperature drop further up the hill by Bumblebees.
