Low Pollen in Aurora, CO

About pollen in Aurora

Grass is the main source of pollen in Aurora today, though levels remain low enough that most people should get through the day without much trouble. Tree pollen is barely registering at this point, a sign that the spring season for trees like ash, maple, oak, honeylocust, and elm has largely wound down. Looking ahead, grass pollen is expected to hold steady at a low level over the next several days, so conditions should stay fairly mild and consistent. This fits the seasonal pattern for early July, when tree pollen has faded and grasses take over as the primary allergen in the area. Anyone particularly sensitive to grass may notice mild symptoms on outdoor days, but overall the pollen picture looks calm for now.
