Low Pollen in Pasadena, TX

About pollen in Pasadena

Grass pollen is the main driver in Pasadena today, sitting in the Low range at a 2 on the Universal Pollen Index, while overall conditions also register Low. Tree pollen reads None right now, in keeping with the season: local allergenic trees like Liquidambar, Celtis, Oak, Elm, and Salix do most of their shedding in spring rather than at the close of June. The forecast keeps grass steady at Low for the next couple of days before easing toward the lower end of the scale later in the period. This timing fits the typical pattern, as grass tends to be the dominant source through late spring and early summer. Weed pollen has no data available today, so it isn't reflected in these readings.
