The honest answer to when you should fly Muscat to Seoul is mostly about weather and demand at the far end. On three years of daily observations at the arrival airport, May-Jun, Sep-Oct gives the most comfortable combination of temperature and rainfall in Seoul.

Weather in Seoul, month by month

Averages below come from three full years of daily readings at Seoul’s main airport, not from a seasonal generalisation. The warmest month is August (average high 29°C), the coolest is January (average low -5°C), and the wettest is July (332 mm).

Climate data: Open-Meteo reanalysis archive.

Packing for the gap: in June, Seoul averages 24°C against 40°C in Muscat — about 16°C cooler, so pack a layer more than you would at home.

Time difference and jet lag

Seoul runs 5 hours ahead of Muscat. Travelling east is the harder direction to adjust to, so if the trip is short, an early departure that lands in daylight is worth more than a marginally cheaper overnight.

When fares move on this route

We publish observed fares for this route when we have them, and say nothing when we do not — there is no estimate on this page. What holds regardless of the route:

  • The travel date matters more than the booking date. Midweek departures are consistently cheaper than Friday and Sunday, because that is when demand actually sits.
  • Comfortable weather and low fares rarely coincide. May-Jun, Sep-Oct is the pleasant window in Seoul, which is also when more people want to go. The shoulder weeks either side of it are usually the better value.
  • School holidays and local events override everything. A festival or a public holiday at either end will outweigh any general booking rule.
  • Set an alert rather than watching manually. Fares move at hours you are not looking, and the useful booking window is weeks wide, not days.

Which day to fly

Midweek departures are consistently cheaper than Friday and Sunday on most routes, because that is where demand sits rather than because of any pricing trick. Where we have observed fares for Muscat–Seoul, the weekday breakdown appears further down this page; where we do not, we leave it out rather than estimate it.
