You sure? Thats the case for areas the size of entire states. You can look at any weather temperature map to prove this.

60 miles is the distance between downtown Seattle and the peak of Mt. Rainier. Downtown Tokyo to the peak of Mt. Fuji. The highest and lowest points in the contiguous US are Death Valley and Mt Whitney, only 80 miles apart, yes that's 20 more than 60 but you get the point here.

Even between places at roughly the same elevation, the climate can vary hugely within 60 miles of a coast. And a majority of the population of the US lives within 60 miles of a coast.

Plains vs mountains are way different biomes. In Texas you can drive 8 hours and maintain similar temps.

If they lived on a mountain, they probably wouldn't be attributing the weather difference to the urban heat island effect.
