Heat Wave Warning Criteria: How Long Will the Heat Wave and Tropical Nights Last?

The scorching heat has continued, with temperatures like the human body temperature.

Since the heat wave began, heat wave warnings have remained in effect day and night, and many people are becoming exhausted by the repeated heat and tropical nights.

Many people are probably wondering how long this unbearable heat wave and tropical nights will continue. Today, we will briefly look at the criteria for issuing heat wave advisories, find out how long the heat wave and tropical nights are expected to last, and also briefly go over ways to manage your health during extreme heat.

Heat Wave Warning Criteria

In Korea, heat wave advisories are issued from June to September when a similar situation is forecast to continue for two days or more based on the daily maximum temperature. This year, in particular, as the heat wave has continued, the number of days with heat wave warnings in effect has also become longer.

The criteria for issuing a heat wave warning are said to be based on temperatures of 35 degrees Celsius or higher. It is issued when the daily maximum perceived temperature is 35 degrees Celsius or higher and such conditions are expected to continue for two days or more.

In addition, if a sharp rise in perceived temperature or a prolonged heat wave is expected to cause significant damage over a wide area, it may also meet the criteria for a heat wave warning. When a heat wave warning is issued, elderly people, children, and those with chronic illnesses need to pay especially close attention to their health.

How long will the heat wave and tropical nights continue?

So far, we have looked at the criteria for issuing a heat wave warning. When the heat wave continues, tropical nights also last longer, making it difficult to get proper rest both day and night, which can easily harm your health.

In particular, as Typhoon No. 9, Jongdari, affected the Korean Peninsula and brought more heat, the heat wave intensified.

If the heat wave and tropical nights continue, they can also affect quality sleep and harm your health. So, how long will the heat wave and tropical nights continue?

It is difficult to predict exactly how long the heat wave and tropical nights will continue, but it is expected to last even longer due to the influence of Typhoon Jongdari.

According to the seasonal calendar, the heat is also expected to continue even after the start of the seasonal term known as Choseo. Although it is impossible to know when the heat wave and tropical nights will end, it is expected that this heat wave may continue in a record-breaking way at least until the end of August.

Health management methods during extreme heat

Summer heat waves are expected to last even longer in the future due to global warming. In particular, people with chronic illnesses need to be even more careful because heat waves can easily lead to heatstroke or worsen existing conditions. For health management during extreme heat, please make sure to keep the following tips in mind.

Preventing dehydration

During periods of prolonged heat, you should make an effort to prevent dehydration.

1. Drink water frequently and regularly. It is good to drink enough in small amounts even if you do not feel thirsty.

2. Avoid caffeinated beverages and alcohol, as they can cause dehydration through their diuretic effect.

3. For people with diabetes, ice cream and soft drinks can raise blood sugar, so drink cold water or barley tea.

Regulating body temperature

When spending a long time outdoors during a prolonged heat wave, it becomes difficult to regulate your body temperature.

1. Keep indoor spaces cool (appropriate indoor temperature: 26–28°C).

2. Take a cool bath, but avoid sudden changes such as pouring cold water over your body all at once.

3. Avoid outdoor activities from 12 p.m. to 5 p.m., when it is hottest, and get plenty of rest.

4. If you must go out, block the sun with a hat or parasol.

Emergency response

1. If chest pain or a feeling of tightness in the chest lasts for more than 30 minutes, go to the emergency room as soon as possible.

2. Let people around you and your family know about any medical conditions you have and any physical changes, and share emergency roles in advance.
