May keeps seated guests at 19°C in the afternoon and around 13°C after sunset — the closest Furano gets to a ceremony that needs neither shade structures nor patio heaters.
Rain falls on roughly 5 days in May (low risk, 30mm). A simple marquee-on-standby is usually enough.
May gives 14.6 hours of daylight and about 10 hours of direct sun per day, so a late-afternoon ceremony puts portraits inside golden hour rather than after it.
November scores 22/100 for weddings in Furano: 4°C highs, 45mm of rain and -2°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 Furano 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 Furano linked below.
May, at 74/100. It combines low rain risk with 19°C afternoons and roughly 13°C evenings, which is the most forgiving combination Furano offers for seated guests.
November scores 22/100: 4°C highs, 45mm of rain over about 10 days and -2°C evenings make a fully outdoor plan fragile.
In May rain falls on roughly 5 of 30 days, so the single-day probability is about 17%. In November that rises to about 33%.
A marquee on standby is usually enough in May, where rain risk is low. Outside the 3 months scoring 65 or higher, book real covered space.
May gives 14.6 hours of daylight and about 10 hours of direct sun. Put portraits in the final 60–90 minutes of daylight so they land inside golden hour rather than after it.
