Click on the city you’re curious about to see the Korea weather in April
Korea weather in April / what to wear in April in Korea is one of the most common questions travelers ask before planning a spring trip, and this guide follows the attached April 2025 city tables and your requested structure. March may be the transition month in many people’s minds, but Korea weather in April is where spring becomes much more active, colorful, and travel-friendly across much of the country. Even so, Korea weather in April is not simply “warm everywhere,” because rainfall, cold snaps, and big city-to-city differences still shape the travel experience.
When travelers search for Korea weather in April, they often expect stable spring sunshine from the first week to the last. In reality, Korea weather in April still changes a lot depending on whether you are on the coast, in a central inland city, or farther south. Some places feel soft and mild quite early, while others still begin the month with cool mornings, damp air, or sudden rainy periods. That is why understanding Korea weather in April city by city is much more useful than relying on one countrywide average.
The best advice for Korea weather in April is to pack for flexible spring conditions. A cardigan, knit top, light jacket, trench coat, comfortable sneakers, and one warmer layer for cooler mornings still make sense in many cities. Korea weather in April often feels ideal in the afternoon, but rainier spells and early-month chill can still catch travelers off guard. If you want to understand Korea weather in April more realistically, it helps to see how the month actually unfolded in different parts of Korea.
Korea weather in April – Incheon
Incheon sits on the northwestern coast of South Korea, and that location gives the city a cooler and windier spring personality than some inland areas. Because of the sea, even mild temperatures can feel sharper than expected, especially when clouds and rain arrive together. Korea weather in April in Incheon often improves gradually rather than all at once, and rain can temporarily pull the city back toward a late-winter feeling. For travelers, this means the city can feel very pleasant at times but still slightly raw during wetter stretches.
Week 1 (April 1–5)
The month opened with a highest temperature of 14.0°C (57.2°F), while the lowest temperature dropped to 4.6°C (40.3°F). Rainfall stayed concentrated at the end of the opening stretch, with 17.7mm on April 5 and no meaningful rain on the earlier dates. The weather felt cool, cloudy, and more subdued than many travelers imagine when thinking about Korea weather in April. Daytime sightseeing was manageable, but the overall mood still leaned closer to early spring than fully comfortable spring warmth.
Week 2 (April 6–12)
The second week brought a highest temperature of 21.3°C (70.34°F), while the lowest temperature fell to 1.3°C (34.34°F). Rainfall totaled 26.8mm, including 0.6mm on April 9 and a much heavier 26.2mm on April 12. The city felt changeable, with some pleasant daytime warmth but a strong wet finish to the week. This was one of those periods when Korea weather in April looked mild on paper but still required weather-aware packing.
Week 3 (April 13–19)
During the third week, the highest temperature reached 20.7°C (69.26°F), while the lowest temperature dropped to 1.2°C (34.2°F). Rainfall totaled 19.4mm, including 1.6mm on April 13, 7.6mm on April 14, and 10.2mm on April 19. The overall feeling was mixed, with cool starts, brighter midweek improvement, and renewed dampness by the weekend. Travelers would have enjoyed parts of the week, but not without an extra layer and some rain readiness.
Week 4 (April 20–26)
The fourth week showed a highest temperature of 24.6°C (76.28°F) and a lowest temperature of 7.7°C (45.86°F). Rainfall was dominated by a single major event, with 42.3mm on April 22 and little meaningful precipitation on the surrounding days. The week felt warmer overall, but the strong rain event made the city feel unsettled in the middle of an otherwise improving spring pattern. Korea weather in April in Incheon became more comfortable here, though still not fully stable.
Week 5 (April 27–30)
The final week reached a highest temperature of 23.5°C (74.3°F), while the lowest temperature stayed at 9.1°C (48.38°F). Rainfall remained absent in this final stretch, so the month closed under drier conditions. The atmosphere felt softer, brighter, and more reliably spring-like than at the start of April. Incheon ended the month in a much friendlier mood for walking, seaside views, and light outdoor plans.
Summary & What to Wear in April in Korea (Incheon)
Incheon in April begins cool and rainy, then gradually becomes milder and more pleasant by late month. Because of its coastal location, Korea weather in April here often feels a bit cooler than inland cities with similar daytime highs. A cardigan, light knit, trench coat, or light jacket works well for most of the month, and a compact umbrella is a smart addition. By late April, lighter spring outfits become more realistic, but wind and rain can still matter.
Q: Does Incheon still feel chilly in April?
A: Yes, especially in the first half of the month and on rainy days. Coastal wind can make the city feel cooler than the temperature suggests.
Q: Is April a good time for coastal walks in Incheon?
A: Yes, especially in the second half of the month when afternoons become milder and drier. Just watch for wind and rain if you are visiting earlier in April.
Q: Do I need rain gear in Incheon in April?
A: It is a good idea. Several rainy spells appear in the monthly pattern, and one heavier rain day can strongly affect comfort.
