October keeps seated guests at 21°C in the afternoon and around 16°C after sunset — the closest Busan gets to a ceremony that needs neither shade structures nor patio heaters.
Rain falls on roughly 3 days in October (very low risk, 46mm). A simple marquee-on-standby is usually enough.
October gives 11.1 hours of daylight and about 4 hours of direct sun per day, so a late-afternoon ceremony puts portraits inside golden hour rather than after it.
July scores 30/100 for weddings in Busan: 29°C highs, 291mm of rain and 24°C evenings make a fully outdoor plan fragile.

Wedding weather is scored differently from travel weather: seated guests in formalwear tolerate a narrower band than sightseers, and the ceremony hour matters more than the daily average. Each month in Busan is scored 0–100 on the weighting below.
| Factor | Weight | What it measures |
|---|---|---|
| Dry conditions | 38% | Share of days with measurable rain — the single factor most likely to force a backup plan. |
| Guest comfort | 27% | Distance from a 22°C daytime ideal, with an extra penalty for humid heat above 24°C. |
| Evening temperature | 20% | Modelled reception-hour temperature against an 18°C ideal for an outdoor evening. |
| Photo light | 15% | Sunshine hours and daylight length, which set the length and quality of the golden hour window. |
Based on long-run climate averages rather than a forecast. Plan the ceremony around the golden hour — see golden hour times for Busan linked below.
October, at 79/100. It combines very low rain risk with 21°C afternoons and roughly 16°C evenings, which is the most forgiving combination Busan offers for seated guests.
July scores 30/100: 29°C highs, 291mm of rain over about 21 days and 24°C evenings make a fully outdoor plan fragile.
In October rain falls on roughly 3 of 30 days, so the single-day probability is about 10%. In July that rises to about 70%.
A marquee on standby is usually enough in October, where rain risk is very low. Outside the 3 months scoring 65 or higher, book real covered space.
October gives 11.1 hours of daylight and about 4 hours of direct sun. Put portraits in the final 60–90 minutes of daylight so they land inside golden hour rather than after it.
