Is ? Que` tiempo hace en la verano? asking what temperature is it in the summer
It should read:¿Qué tiempo hace en el verano? and means what is the weather like in the summer, verano is masculine so it is el verano and not la verano as stated in the title.
Welcome to the forum, While you do have part of your answer the other part can, obviously, only be answered by a specific person at a specific time and place. Here and right now in New Hampshire it happens to be ¡hace frio!
Temperatura in spanish means temperature in english. tiempo means time but when used in the context of the above question it means weather so the question is asking what kind of weather do they have in summer at the place where the question is being asked so if we were being asked tha question in spain I would say hace mucho sol and if I was asked that question about england I would say llueve mucho.
