Monsoon, typhoon and heat wave travel safety

Korea's monsoon season, called jangma, usually runs from late June to late July. By the Korea Meteorological Administration's climate averages, it starts around June 19 on Jeju, June 23 in the south and June 25 in the central region. Start and end dates vary a lot from year to year, so check the forecast right before your trip.

Typhoons mainly affect Korea between summer and early autumn. The southern coast and Jeju are often the first to feel strong winds and heavy rain. A typhoon's track can shift within days, so if you travel during this period, check the Korea Meteorological Administration's typhoon updates daily.

Yes. Even in the monsoon season it does not rain every day, so travel is perfectly possible. However, sudden heavy downpours are common, so prepare indoor alternatives such as museums, markets and performances. Keep plans that depend heavily on weather, like valleys or island trips, flexible.

The Korea Meteorological Administration's website and app show real-time warnings for heavy rain, typhoons and heat waves. Emergency alert messages sent to your phone are another key source. You can also ask your accommodation staff or call the 1330 tourist hotline for help.

Phones connected to a Korean mobile network can receive emergency alerts, but the main text is in Korean. Since February 2024, the most urgent alerts that sound an alarm also show the type of disaster in English. For fuller foreign-language information, install the Ministry of the Interior and Safety's Emergency Ready App.

The Emergency Ready App is a disaster safety app from the Ministry of the Interior and Safety for foreigners. It delivers emergency alerts and safety guidelines in foreign languages and shows nearby shelters and cooling centers. After installing it, choose your language and region in the settings.

During heavy rain, stay away from riverside paths, valleys, underpasses and underground spaces where water can rise quickly. Steep slopes and cut hillsides carry a landslide risk. Always obey barrier tape and closures, and never cross flooded roads on foot or by car.

After heavy rain, valley streams can surge suddenly and sea waves can grow rough, so it is safer to postpone swimming. Even under clear skies, rain upstream can make the water rise rapidly. Always follow swimming bans and lifeguard instructions.

When typhoon or high-wave warnings are issued, flights and ferries are often canceled or delayed, and trains and roads can be affected too. For ferries, the local coast guard decides whether departures are restricted. Check official airline, ferry and rail notices often and leave slack in your schedule.

While a typhoon passes, avoid going out and stay away from windows. Charge your phone and power bank in advance and keep some water and simple food on hand. Also check the evacuation guidance and emergency exits your accommodation provides.

A heat wave advisory is issued when the daily maximum apparent temperature is expected to stay at 33°C or above for at least two days, and a heat wave warning applies at 35°C or above. Criteria can change, so check the weather agency's guidance and cut back on midday outdoor activity when an alert is out.

Cooling centers are air-conditioned spaces designated by local governments where anyone can escape the heat during heat waves. Many are public facilities such as community service centers, libraries and senior centers. You can find locations in the Emergency Ready App or local government notices, and hours vary by site.

If you notice dizziness, headache, nausea, heavy sweating or muscle cramps, move to a cool place right away, rest and drink water. Loosen your clothes and cool your body down. If the person becomes confused or has a very high body temperature, call 119 immediately.

A tropical night is a day when the overnight minimum temperature stays at 25°C or higher. In midsummer, nights can be hot and humid enough to disturb sleep, so choose air-conditioned accommodation. If you walked a lot during the day, keep drinking water in the evening and avoid overly demanding outdoor plans.

A sturdy umbrella or light raincoat, quick-drying clothes, spare socks and non-slip shoes are all useful. A waterproof phone pouch and a power bank are worth bringing too. Because humidity is high and laundry dries slowly, pack a few extra clothes.

Convenience stores sell umbrellas and disposable raincoats almost everywhere, so a sudden shower is easy to handle. Shops around subway stations often sell them too. Some local governments and facilities also run umbrella-lending services, so look for notices on site.

It is safest to avoid hiking when heavy rain warnings are in effect or right after a downpour. National parks may close trails during heavy rain, and paths that cross streams become dangerous as water rises. Check closures on the Korea National Park Service website before you set out.

Check the weather-related cancellation and change policies for flights, accommodation and tours before you book. If a flight or ferry is canceled, follow the carrier's official instructions for rebooking or refunds. If you have travel insurance, read the policy to see what it covers.

Call 119 if a life is at risk or you need rescue, and 112 to report crimes or accidents to the police. For travel-related help or interpretation, call the 1330 tourist hotline. If it is hard to explain where you are, mention nearby building names or share what your map app shows.

Be careful right after a typhoon, since fallen trees, downed power lines, flooded roads and loose rocks may remain. First check whether access restrictions on coasts and mountains have been lifted. Transport may also stay delayed for a while, so follow official notices before heading out.
