July keeps seated guests at 22°C in the afternoon and around 16°C after sunset — the closest Whistler gets to a ceremony that needs neither shade structures nor patio heaters.
Rain falls on roughly 3 days in July (very low risk, 18mm). A simple marquee-on-standby is usually enough.
July gives 15.7 hours of daylight and about 11 hours of direct sun per day, so a late-afternoon ceremony puts portraits inside golden hour rather than after it.
December scores 9/100 for weddings in Whistler: 2°C highs, 63mm of rain and -3°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 Whistler 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 Whistler linked below.
July, at 88/100. It combines very low rain risk with 22°C afternoons and roughly 16°C evenings, which is the most forgiving combination Whistler offers for seated guests.
December scores 9/100: 2°C highs, 63mm of rain over about 14 days and -3°C evenings make a fully outdoor plan fragile.
In July rain falls on roughly 3 of 30 days, so the single-day probability is about 10%. In December that rises to about 47%.
A marquee on standby is usually enough in July, where rain risk is very low. Outside the 3 months scoring 65 or higher, book real covered space.
July gives 15.7 hours of daylight and about 11 hours of direct sun. Put portraits in the final 60–90 minutes of daylight so they land inside golden hour rather than after it.
