I think it is known as “the shot” of the Taj Mahal, which I took in high summer. You can’t see it here, but it was over 40 C (100 F), and this was the time of year that tourists stay away.
Whether it is the desert in mid-summer or Warsaw in mid-Winter . . . you don’t just save money, but also you get an interesting (or even better) view of touristy places when you travel during the off-season.
