Phoenix, Arizona – A calm desert morning greets early risers as clear skies stretch across the Valley. Streetlights fade against a dark blue horizon, and cool air lingers just long enough to notice. That chill won’t last.
According to the National Weather Service, temperatures climb quickly today, reaching the upper 70s under full sunshine. Winds remain light, and visibility stays clear, keeping travel smooth across I-10, Loop 202, and surface streets during the morning commute.
This pattern signals a notable warm stretch setting up across central Arizona. Afternoon warmth builds steadily through the weekend, with Sunday shaping up as the hottest day so far. Highs push into the low 80s, several degrees above seasonal norms. The dry air keeps humidity low, making the warmth feel comfortable but deceptively strong under direct sun.
Saturday stays sunny with highs near 78. Sunday adds a few passing clouds late, but heat still peaks near 81. Outdoor plans should include hydration and sun protection, especially during midday hours. Even in January, sun exposure adds up quickly in the desert.
Overnight lows remain mild, settling in the upper 40s to low 50s. Calm winds limit cooling, and patios stay comfortable after sunset. Early mornings continue to feel crisp but brief.
Looking into early next week, temperatures ease slightly but remain above average. Monday and Tuesday hover near the upper 70s with mostly sunny skies. No rain is expected, and travel conditions remain quiet across the region.
This warming trend contrasts sharply with the deep winter cold gripping much of the central and eastern U.S. While Arctic air drives dangerous conditions elsewhere, the Southwest sits firmly on the mild side of the pattern for now.
