如何显示填充有对象 ionic angular 的数组中的数据

Question

I am trying to display data from a weather api but i dont know how to do it because i cant show anything. This is how i recieve the data when I do console.log(this.tiempo), as an array filled with objects

But when i try to access to any object like this.tiempo.descripcion, it shows me an undefined. Why?

This is my method to pass data between pages

openDetails(){
    let navigationExtras: NavigationExtras = {
      state: {
        previsiones: this.previsiones
      }
    }
    this.router.navigate(['meteorologia'], navigationExtras);
  } 

And here I can treat it

tiempo: IMeteorologia;
  constructor(private activeRoute: ActivatedRoute, private router: Router) 
  {
    this.activeRoute.queryParams.subscribe(params => {

      if (params && params.special) {
        this.tiempo = JSON.parse(params.special);
      }

      if (this.router.getCurrentNavigation().extras.state) {
        this.tiempo = this.router.getCurrentNavigation().extras.state.previsiones;
        console.log(this.tiempo.descripcion) //Here is the undefined
      }
    });
  }

This is my interface

export interface IMeteorologia {
    descripcion: string;
    diaSemana: Date;
    tempMinima: string;
    tempMaxima: string;
}

I hope I explained myself well.

Fixed it. I was populating the array incorrectly
