Korea Weather in June – What to Wear and Rainy Season Tips

이미지
June in Korea feels less like the end of spring and more like the real beginning of summer. In Seoul, daytime highs are often around 25–28°C (77–82°F), but recent years have brought early summer heat even in May. If you are visiting Korea in June, prepare for strong sun, rising humidity, powerful indoor air conditioning, and the beginning of Jangma , Korea’s summer rainy season. 1. What to Expect: June Weather and Temperature in Korea Planning a trip to Korea in June? This is the season when the last traces of spring begin to fade and summer starts to take over. These days, June feels much closer to early summer than a gentle spring-to-summer transition. In fact, in recent years, Korea has sometimes seen temperatures close to 30°C even in May, so seeing people in short sleeves before June no longer feels unusual. In Seoul, daytime highs in June are usually around 25–28°C (77–82°F). On paper, that may not sound like extreme summer heat. But once strong sunlight and humidity a...

Korean Chili Peppers – Types, Spice Levels, and How to Choose the Right One

Last spring, we planted 12 chili pepper seedlings on our rooftop garden. It was fascinating to watch how the spice and texture changed depending on the weather. Today, let’s explore five popular types of Korean peppers you can easily find in stores, along with their surprising health benefits.

To be honest, the rooftop garden is my husband’s dedicated project. He finds a lot of simple pleasure in watching his plants grow day by day. Since moving to a house, he takes care of watering and catching bugs, while I only enjoy the best part—harvesting with my two kids!

1. Why Korean Chili Peppers Get Spicier – Climate and Capsaicin Explained

Last spring, we planted twelve chili pepper seedlings in our rooftop garden. At first, we didn’t think much about spice levels at all. But as time passed, we began to notice clear changes in both heat and texture.

I used to love spicy food and always kept Cheongyang peppers in the freezer. But after having two children, I became a 'Map-jjil-i' (a Korean slang for someone who can't handle heat). Now, I’m a bit scared of how spicy our homegrown peppers have become!

The early harvests were mild and tender, with almost no spiciness. As summer arrived and temperatures rose, the same plants started producing firmer peppers with a noticeably stronger heat. Even familiar green chilies gradually developed a sharper bite.

This happens because chili peppers respond to intense sunlight and heat by producing more capsaicin. As they lose moisture and the flesh becomes firmer, both the texture and the level of spiciness increase.

Watching this process firsthand made me realize something I could never notice when simply buying peppers at the store. Seeing how their heat develops as they ripen was a completely different experience. Even in our small rooftop garden, it became a meaningful moment for me and my children, as we learned how the flavor of chili peppers can change depending on their growing environment while sharing the joy of harvesting together.

2. Five Common Korean Chili Peppers You’ll Find at the Market

After growing chili peppers at home, the ones I used to see at the market started to look a little different. I used to think they were all quite similar, but now I notice that each type has its own flavor and purpose. Here are five common Korean chili peppers you can easily find and how they are typically used.

  • Putgochu (Green Chili) has a crisp texture with a mild level of heat. It’s especially refreshing when eaten raw with ssamjang during the summer. It’s one of the most commonly enjoyed peppers in everyday Korean meals.
  • Cheongyang Pepper is small, firm, and very spicy. It’s often used to quickly add heat to soups and stews. Even though I’ve become more sensitive to spicy food over time, my husband still adds plenty of these to his ramen when he feels a cold coming on. He says sweating it out makes him feel much better.
  • Oe-gochu (Cucumber Pepper) is large, juicy, and very crunchy. It’s mild enough for anyone to enjoy without feeling overwhelmed by the heat. Both green chili and cucumber pepper are great for eating raw, but I personally find myself reaching for cucumber peppers more often because of their crisp texture and larger size.
  • Ggwari-gochu (Shishito Pepper) has a wrinkled appearance and a soft texture. It’s commonly stir-fried and pairs especially well with anchovies or small shrimp. When cooked with soy sauce, it develops a deep umami flavor and pairs perfectly with rice. Just be careful not to overcook it, as it can quickly lose its texture—briefly stir-frying it at the end is the key.
  • Hong-gochu (Red Chili) is fully ripened and bright red. It’s commonly used to add color to kimchi or dried to make chili powder. While the level of spiciness can vary, it plays an important role in enhancing both the color and flavor of Korean dishes.

3. Nutritional Benefits of Korean Chili Peppers – More Than Just Heat

Chili peppers are more than just spicy ingredients. They are rich in vitamin C, antioxidants, and capsaicin. In particular, fully ripened red chili peppers are known to contain two to three times more vitamin C than oranges. Thinking about this made me wonder if kimchi, which uses a generous amount of chili powder, might be more nutritious than we usually expect.

Capsaicin, the compound responsible for spiciness, is known to support blood circulation and help relieve stress. That’s also why spicy food often makes you sweat and feel refreshed afterward. Personally, I sometimes find myself craving spicy food when I feel stressed, and I end up reaching for tteokbokki.

Chili peppers that receive more sunlight tend to have higher levels of antioxidants. In Korea, sun-dried chili peppers, known as taeyangcho, are considered higher in quality in both flavor and nutrition, which is why they are often more expensive. You can even find many products in the market labeled with “taeyangcho” to highlight this.

Each type of chili pepper has its own shape, aroma, and level of heat, which makes choosing the right one for each dish part of the fun of cooking. Milder peppers are great for eating raw, while Cheongyang peppers add depth to soups. Ggwari-gochu works well in stir-fried dishes, and red chili peppers enhance both the color and appeal of the food.

Korean chili peppers are not just about heat—they bring balance in flavor, color, and texture, and naturally add depth to everyday dishes.

In Korean cuisine, garlic is just as essential as chili peppers. In fact, there’s a famous legend that the very first "Korean" was born after a bear endured 100 days of eating only garlic and mugwort (bitter herbs) in a dark cave. It wasn’t just about food, but a story that reflects patience and transformation.

Curious how a bear became a human with these two plants? I’ll share the fascinating story of the Dangun Myth in my next post!
