Which word correctly completes this conversation? ernesto: matilde, ¿cómo es el clima en otoño en tu ciudad? matilde: en mi ciudad durante el otoño frío. está usa hace tiene

In this case, the Spanish verb hacer refers to weather conditions or atmospheric temperature.

In this way the verb hacer in its many conjugations works as an impersonal verb, that is, it is conjugated in the third person in singular, without any reference to the subject.

According to this rule, the correct option is hace frío.

Therefore the complete sentence is:

In my city during the autumn it is cold
