Hello, this is 속초어때 (Sokcho Eottae). At 10 p.m. on Tuesday, August 18, if you're out by the shore in Sokcho (속초), you've probably already noticed it. Nearly three hours have passed since sunset, yet the air still hasn't cooled. The temperature in Sokcho right now is 26°C, with humidity at 85%. The asphalt and concrete baked by the daytime sun are giving that heat straight back, and the wind off the sea is only about 1 m/s, so you barely feel it on your skin. And the weather advisory announced at noon today is still unchanged. A heat wave advisory is in effect for the Sokcho lowlands and the Sokcho mountain areas. It isn't lifted automatically once night falls — whether to keep it in place is decided together with the next day's temperature outlook.
Tonight Is Another Tropical Night
Last night the pre-dawn temperature fell to 24°C, breaking the tropical nights for one day, but tonight they resume. Looking at the hourly forecast: 25°C at 11 p.m., 25°C at midnight, and 25°C at 1 a.m. and 2 a.m. as well — it won't drop below 25°C all night. A tropical night means a minimum temperature of 25°C or higher, so tonight sits right on the line. There's a stretch at 11 p.m. when the chance of rain briefly rises to 20%, but after midnight it falls back to 0%. It's the kind of thing where a passing cloud might sprinkle for a moment, so it's not a situation that calls for an umbrella.
There's a reason summer nights in Sokcho feel especially sticky. When humidity climbs to 85%, sweat can't evaporate. Your body sweats to bring its temperature down, but the sweat doesn't dry — so it feels far hotter than the actual temperature. Add weak wind on top of that and it feels worse still. Tonight is exactly that combination.
- Air conditioning at 26–27°C combined with a fan works better. Rather than dropping the temperature to 22°C, setting it at 27°C and circulating the air means waking up less during the night.
- If you're going to open the windows at your accommodation, open the window on the opposite side as well, not just the sea-facing one. Opening only one side means the air won't move through.
- It's better to wash with lukewarm water before bed. Cold water feels cool for a moment, but as your blood vessels constrict and then dilate, your body temperature actually goes up.
- If the air conditioning at your accommodation is weak and it's hard to bear, Sokcho has 24-hour cafés and large convenience stores clustered around the beaches and near 중앙시장 (Jungang Market). So there are refuges to get you through until 2 or 3 a.m.
Tomorrow, Wednesday, Highs Climb to 31°C
The forecast for Sokcho on Wednesday, August 19 is a high of 31°C and a low of 25°C. Skies will be mostly clear to partly cloudy, and the chance of rain stays in the 10–30% range all day. It's a day when you can schedule outdoor plans without worrying about rain. That said, when daytime temperatures top 30°C and humidity is high, the perceived temperature climbs above 33°C. That's why the heat wave advisory is likely to continue through tomorrow.
Tomorrow's sunrise is at 05:44. Compared with early August, sunrise has slipped by nearly 15 minutes. It's the most honest sign that summer is winding down. In the end, the only way to escape the heat is to shift your timing, and in Sokcho the most efficient window is between 6 a.m. and 9 a.m. During those hours the temperature sits around 26–27°C and the parking lots at tourist spots are empty. Yeonggeumjeong (영금정) at sunrise, the Oeongchi Badahyanggi-ro (외옹치 바다향기로) coastal trail, and the Cheongchoho (청초호) walking path all feel like completely different places when you walk them at this hour. Conversely, between 1 p.m. and 4 p.m. it's right to avoid outdoor activity.
Water Temperature 26.1°C, Wave Height 0.4 m - the Sea Is Calm
The water temperature off Sokcho right now is 26.1°C, with a wave height of 0.4 m. A wave height of 0.4 m is practically lake-like. Compared with the days last week when swells came in and topped 2 m, it's a completely different sea. At a water temperature of 26°C, there's no "cold" sensation at all when you get in, so it's easy going even for children or people who are afraid of the water.
You do have to check the hours, though. Night opening at Sokcho Beach already ended on August 12. From July 21 to August 12, entering the water was permitted until 9 p.m. along a 130 m stretch around the central walkway, but now it's back to the regular hours: you may enter the water only from 9 a.m. to 6 p.m. Going into the sea at this hour means entering with no lifeguards and no staff managing the harmful-organism nets, which is extremely dangerous. For the night sea, walking with just your feet in the water is plenty.
And this summer, Sokcho's beaches close on Sunday, August 23. That wraps up 52 days of operation since the July 3 opening. It's the same day for all four — Sokcho, Deungdae, Oeongchi, and Cheongho. If you still have plans to get in the water, the remaining days are now countable on one hand.
Tomorrow Is 14-mul, With the Morning High Tide at 06:53
Let's also go over the tides. Today, August 18, was 13-mul, and tomorrow, August 19, is 14-mul. The tide times are as follows.
- Low tide 00:34 / 14:23
- High tide 06:53 / 21:11
- Sunrise 05:44 / Sunset 19:15
The East Sea (동해) doesn't have a large tidal range like the West Sea, so many people don't pay attention to the tides. In fact, tomorrow's tidal difference is only about 10 cm. Still, it's useful to know. Around high tide the beach narrows and the waves push in close to the breakwater. If you head to Yeonggeumjeong or Deungdae Beach (등대해변) around tomorrow morning's 6:53 high tide, the waves breaking on the rocks are far more refreshing. Conversely, around low tide at 2:23 p.m. the water pulls back, the beach widens, and tide pools among the rocks are exposed. If you're looking for shellfish or small fish with the kids, that's the right time slot. Just note that 2 p.m. is the hottest hour of the day, so a hat and water are essential.
It's 10 p.m. and All Three Access Roads Are Moving Slowly
As of right now, the situation on Sokcho's main access roads is: Misiryeong-ro (미시령로, toward Seoul) slow, Donghae-daero (동해대로, coast and downtown) slow, and Seoraksan-ro (설악산로, toward Seorak) slow. These figures are estimates based on traffic volume and may differ from what you actually experience, but three directions moving slowly at once at 10 p.m. means there are that many people out and about downtown.
Congestion at tourist spots is still going strong, too. 금호리조트 설악 (Kumho Resort Seorak) is very congested, while 부엉이전시관(해피아울하우스) (Bueong-i Jeonsigwan / Happy Owl House), Daepo Port (대포항), the Daepo Port observatory, Deungdae Beach, and 마레몬스 호텔 (Maremons Hotel) are at the congested level. Accommodations sitting at the top of the congestion range is a trace of check-ins piling up, and Daepo Port and Deungdae Beach being busy even at 10 p.m. means demand for late-night food and the night sea is still there. In fact, statistics have shown that Sokcho has recently seen visitors, overnight stays, and spending rise together with "stay-type tourism." It's changing from a city people come to for the day into one where they stay a night or more.
- If you're heading to the 대포항 raw fish center now, give up on the parking lot inside the harbor and park on the outskirts, then walk in — it's faster.
- If you're planning to set off for Seoul, after midnight is easiest. If you head toward Misiryeong now, just getting out of downtown takes time.
- Most dakgangjeong shops at 중앙시장 close between 9 and 10 p.m. If you're after late-night food, Daepo Port or the Cheongho-dong (청호동) direction is the realistic option.
Sokcho This Week: Here's What's Left on the Calendar
August in Sokcho isn't over yet. The biggest event is Waterbomb Sokcho 2026, held on Saturday, August 22. It takes place around 한화리조트 설악 (Hanwha Resort Seorak); only those aged 19 and over may enter, and ID checks are mandatory. The detailed lineup and performance times are being released in stages through official channels, so if you've booked tickets, checking Instagram and the official website is the accurate way to go. The city has stated that it has completed its review of safety and traffic measures, but severe congestion is expected on Seoraksan-ro and on the approach to the resort that day. If you're heading toward Seorak for reasons unrelated to Waterbomb, we recommend moving on Saturday morning or avoiding the date altogether.
And Sunday, August 23 is the beach closing day. The day after Waterbomb is effectively the last day of summer, so this weekend Sokcho will be crowded on a big scale for the last time this summer. It's already finished, but the Displaced Persons Culture Festival (실향민문화축제) drew some 66,000 people over two days and generated 9.3 billion KRW in spending, and the light and sound programs that continued along the beach have filled Sokcho's August nights. The few remaining days are the wrap-up.
In Short, Here's How to Move Tonight and Tomorrow
- Tonight: 26°C tropical night, heat wave advisory still in effect. Keep outdoor activity to about a night walk. Entering the sea is not allowed.
- Tomorrow pre-dawn to morning: sunrise 05:44, high tide 06:53. From 6 to 9 a.m. is the most comfortable stretch of the day.
- Tomorrow daytime: high of 31°C, chance of rain 10–30%. From 1 to 4 p.m., stick mainly to indoors.
- Tomorrow's sea: water temperature 26.1°C, wave height 0.4 m, swimming hours 9 a.m. to 6 p.m.
- Low tide at 14:23: the time the beach widens — good for playing among the rocks.
속초어때 checks and compiles the weather, the sea, the tides, and road conditions hour by hour like this. That's because travel plans ultimately come down to "what time you move and where." Even at the same 31°C, 31°C at 7 a.m. and 31°C at 2 p.m. make for completely different days.
Today we covered the heat wave advisory situation and the tropical night in Sokcho on the night of Tuesday, August 18, tomorrow's Wednesday temperatures and the 14-mul tide, plus road and congestion conditions as of 10 p.m. — did you find it useful? We'll be back next time with even more useful information.
