April keeps seated guests at 24°C in the afternoon and around 16°C after sunset — the closest Las Vegas gets to a ceremony that needs neither shade structures nor patio heaters.
Rain falls on roughly 1 days in April (very low risk, 5mm). A simple marquee-on-standby is usually enough.
April gives 13 hours of daylight and about 9 hours of direct sun per day, so a late-afternoon ceremony puts portraits inside golden hour rather than after it.
August scores 47/100 for weddings in Las Vegas: 41°C highs, 11mm of rain and 32°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 Las Vegas 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 Las Vegas linked below.
April, at 91/100. It combines very low rain risk with 24°C afternoons and roughly 16°C evenings, which is the most forgiving combination Las Vegas offers for seated guests.
August scores 47/100: 41°C highs, 11mm of rain over about 3 days and 32°C evenings make a fully outdoor plan fragile.
In April rain falls on roughly 1 of 30 days, so the single-day probability is about 3%. In August that rises to about 10%.
A marquee on standby is usually enough in April, where rain risk is very low. Outside the 7 months scoring 65 or higher, book real covered space.
April gives 13 hours of daylight and about 9 hours of direct sun. Put portraits in the final 60–90 minutes of daylight so they land inside golden hour rather than after it.
