views.py

from urllib import request
from django.shortcuts import render

import requests
from datetime import datetime
from .models import City
from pytz import timezone
from django.views.generic import ListView

from .forms import CityForm
from django.views.generic.edit import FormMixin, FormView


class Cities(FormMixin,ListView):
    model=City
    template_name='home.html'
    form_class=CityForm
    success_url='/'


    def get_context_data(self, *, object_list=None, **kwargs):
        context =super(Cities, self).get_context_data(**kwargs)
        
        weather_data=[]

        for city in City.objects.all():
            url=f'https://api.openweathermap.org/data/2.5/weather?q={city}'
            data=requests.get(url).json()
 
            if data["cod"] != "404":

                now_asia =datetime.fromtimestamp(data['timezone']).strftime('%a,%b %d %Y')
                payload={   'city':data['name'],
                    'weather':data['weather'][0]['main'],
                    'icon':data['weather'][0]['icon'],

                    }

                weather_data.append(payload)
            else:
                weather_data={'invalid_city':f'{city} City not found.\n Enter valid city'}
        print(context)
        context={'weather_data':weather_data}
        return context

    {% csrf_token %}
    {{form}}
    <button class="btn" type="submit" >Add city</button>

In get_context_data change at the end

   context['weather_data'] = weather_data
   return context

You just want to add another key but not overwrite the whole context
