What summer?

There was a fire evacuation drill in the office yesterday morning. All the people in the office gather on the street. I was chatting with Chirag, an Indian who has been living in Edinburgh for more than 2 years:

Chirag : "How do you find the summer?"

I: "??"

Indian: "Do you notice that it is summer now?"

I : "Is it summer?"

Andrew, who is from Zambia in the Africa and has been here for more than 1 year, said: "What summer?"

Temprature yesterday morning: 12 degrees centigrade high.
