Late March to early June, or mid-September to early November. These shoulder seasons offer the most comfortable temperatures (highs 75–84°F spring, 78–82°F fall), lower humidity than summer, and major events (Fiesta in April). WeatherSpark identifies late April as the single best week for outdoor tourism. Summer highs exceed 95°F with high humidity. Fall avoids peak crowds while retaining warmth
