In Como, Italy, pollen seasons start in late winter. This is when trees like hazelnut and alder begin to bloom. They release tiny particles into the air.
Updated: 2/9/2026
From March to May, pollen counts go up. Trees like oak, birch, and beech release more pollen. This can make it hard to be outside.
In the summer, grasses release pollen. This can be a problem for people who spend time outdoors. Parks and gardens can be especially bad.
In the fall, weeds like ragweed release pollen. This can be a problem until the first frost. Then, pollen counts go back down, and the air is cleaner.
