About pollen in Lancaster
Weed pollen is the main contributor to today's moderate conditions in Lancaster, and those sensitive to it may notice some effects, particularly outdoors during the afternoon. Grass pollen remains at a very low level and is unlikely to cause much trouble, while tree pollen is absent entirely, which is typical for this point in the year. Over the next few days, expect little change: weed pollen should hold steady before easing slightly toward the end of the week, grass will stay consistently low, and trees are expected to remain quiet. This pattern fits the season, as late summer and early fall in the high desert are typically dominated by weeds such as ragweed and sagebrush, while tree pollen from species like oak and juniper won't become a factor again until closer to spring.
