Is the temperature of 28 degrees high?

The weather forecast not only predicts the weather tomorrow, but also predicts the temperature tomorrow.

Sometimes the highest temperature is predicted, such as 35 degrees, 38 degrees, 4 1 degree, etc. If it is 4 1 degree, it is actually very hot. But I personally measured the temperature of 49.5 degrees at noon, which was quite different from the weather forecast.

I asked my teacher this question, and the teacher told us that there are four time points every day, two during the day and two at night. Add up the four collected temperatures and divide by four to get the average temperature.

However, the weather forecast did not say so. The general weather forecast will say "Beijing, sunny, 10 to 20 degrees".

Excuse me, what does 10 degree stand for and how is it measured?

What does 20 degrees represent and how to measure it?

Supplementary question: You don't understand me.

Suppose I measure every hour and get 24 10 degrees, but the temperature reaches 40 degrees every half hour. Should it be recorded as "highest 10 degree, lowest 10 degree"? Of course, this is just a hypothesis.

I don't know how many times I measure now. In the past, the teacher said it four times. In other words, the lower the measurement frequency, the easier it is to miss some data.

I know the definition of temperature very well, and I also know when it is usually the hottest and coldest in a day. I mean, does "maximum temperature" mean the highest value in measured data or the highest value in actual temperature?

"The traditional forecasting method provides services for the public with 24-hour process forecasting for a long time, which is divided into two time periods: day and night. After starting the 6-hour refined forecasting service, the weather forecast is refined into 4 time periods, and the public can know the weather phenomenon, maximum and minimum temperature, precipitation, prevailing wind direction and maximum wind power every 6 hours within 24 hours, in which the precipitation will be accurate to the millimeter.
