Meibanfa hit it right on. Due to the high desert climate, days are warm (and usually sunny) but the temps drop off quite quickly. On average the temperature swing is about 15-20°C between night lows and daytime highs. Also, Santa Fe is typically 5-10°C cooler than Albuquerque at any given time. I also second the recommendation for fall visiting. The monsoon rains have died out and the winds are less of an issue than summer time.
October is also a great time for traveling near the river and in the mountains as the trees are changing colors. Albuquerque has a nice trail along the river through the forest (Bosque) and mountain biking on the east side of town near the main mountain range (the Sandias).
If you are looking to save money, avoid Albuquerque from 5-13 October. Unless you want to see the Balloon Fiesta (which is awesome to see), you'll have a hard time finding hotel accommodations and prices will skyrocket.
