Mountain cedar runs from December to March in the west of the region, and oak leads the spring. This month sits outside the usual tree pollen window for the Gulf & South Texas pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Louisiana allergy season guide singles out an early February tree start and outdoor mold, elevated much of the year in the Gulf humidity.
