PHOENIX, Ariz. — The desert dawn breaks warm and golden this Tuesday morning, the kind that makes the Valley of the Sun shimmer before sunrise. October is nearly done, but it feels more like late summer as Phoenix braces for one more stretch of 90-degree heat before a subtle Halloween cool-down arrives.
According to the National Weather Service in Phoenix, temperatures will climb to near 92°F today under clear skies and light northeast breezes. That’s roughly 10 degrees above the seasonal norm. For residents with outdoor chores or afternoon errands, hydration and sun protection remain key — even in late October, the desert heat still holds some bite.
By Wednesday, highs near 90°F will mark the final burst of warmth before a gentle slide back into the upper 80s Thursday and Friday. Winds stay light and humidity remains low, keeping evenings comfortable and mornings crisp in the low to mid-60s. Trick-or-treaters across metro Phoenix can expect nearly perfect Halloween conditions: mild, dry air, calm winds, and clear skies for Friday night festivities.
Looking ahead to the weekend, Saturday and Sunday hold steady near 87–88°F with plenty of sunshine — ideal for yard work, festivals, or a late-season desert hike. Early November models hint at a more noticeable cooldown next week as desert nights begin to feel truly fall-like.
Five-Day Outlook for Phoenix, AZ:
Tue: 92/65 – Sunny, hot; light northeast wind.

Thu: 88/63 – Clear and calm.
