Tehran is situated in a continental climate zone with hot, dry summers, while Lisbon has a Mediterranean climate with milder temperatures. Additionally, Tehran is located at a higher latitude and elevation compared to Lisbon, which can contribute to higher temperatures.

Why is tehran hotter than lisbon in summer？-Well, there are several reasons for that. First of all, Tehran is located in a region with a drier climate in summer. There's less moisture in the air, which can make it feel hotter. Also, the geographical location and altitude play a role. Lisbon is closer to the ocean, which has a moderating effect on the temperature. But Tehran is farther inland and doesn't get that cooling influence from the sea. Oh, and another factor could be the urban heat island effect. Tehran might have more concrete and buildings, which retain and generate more heat. So, that's why Tehran can be hotter than Lisbon in summer.
