Western Colorado does not typically experience pollen release during the months of December and January. Tree pollens usually begin to release pollen in late February in this region. On warmer days during the winter, there may be mold depending on the level of dampness. Also, remember to consider possible indoor causes of allergies and irritants if you are experiencing more symptoms during the winter month.
If you find that your respiratory symptoms are more severe during times when pollen and mold counts are low, then consider other potential causes, including allergic and non-allergic causes. During cooler months, indoor allergens are often a problem, such as pet dander and dust mite (depending on local environment). Non-allergic causes of nasal and sinus symptoms in Western Colorado are also common, especially during the spring and fall. These are frequently related to dryness, dust, wind, and irritants such as from open burning.
As far as we know, this is the only active pollen counter in Western Colorado. We report what we see. Most other pollen reports online utilize computer modeling to estimate likely pollen trends. Such computer modeling has limitations and we find frequent discrepancies with our "real-life" measurements.
