When is the hottest in summer? When do you turn on the air conditioner in summer?

In the past, the hottest time in summer was from mid-July to mid-August. Due to the global greenhouse effect, the high temperature in summer starts ahead of schedule. In some areas, the weather has been very hot since late June. It's best to take sun protection measures early. When the sun is strong, you should wear sunscreen in the morning and bring a hat, sunglasses and an umbrella. If you feel that it is too hot indoors, you can put a basin indoors and turn on the air conditioner to cool down.

1, seasonal variation

According to the season, the hottest time in summer is July and August, which basically enters the dog days. But in June, people actually feel very hot, because the global greenhouse effect makes the temperature rise earlier, and the ozone layer is thinner every year, which makes the ultraviolet rays stronger. The most intuitive thing is that after the arrival of summer, the sun becomes very toxic, and the weather has become hot since long summer. Therefore, people should start to strengthen sun protection measures as soon as possible. If they want to go out, they must wear sunscreen and prepare sunglasses and sunglasses.

2. Hot and rainy days

The period before the rainstorm in summer is the most uncomfortable. The sultry feeling will make people feel a little hotter than usual. This sultry rainy day is unavoidable indoors. You can only take a cold bath to lower your body temperature. At this time, turn on the air conditioner to blow dry the air and lower the indoor temperature, and you will feel more comfortable. If you still feel too hot and stuffy, you can have some cold drinks or herbal tea to cool down.

3. High temperature period

It is very hot in summer from 10 to 5 pm, in which the sun is strongest at noon and the ground is hottest at 2 pm. If the house is sultry and humid, you might as well open the window at 8 am for ventilation, close the doors and windows and turn on the air conditioner around 10 am, and the temperature can be set at about 20 degrees Celsius, depending on your personal preference and cold and hot tolerance. After the hot afternoon, you can turn off the air conditioning balance fan at around 4 pm to adjust the internal and external temperatures.
