For outdoor Las Vegas wedding ceremonies, early morning and late afternoon are often the most comfortable and photo-friendly times. Midday can be bright, hot, crowded, and harder for photos, especially during warmer months.
The best time depends on the season, location, guest count, lighting, permit windows, parking, and how much walking is required. Desert, park, Strip, Downtown, and lakeside ceremonies can all feel very different, so it helps to choose a time that matches both the location and your comfort level.
