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 Texas allergy season guide singles out mountain cedar — Ashe juniper — in winter, oak in spring and ragweed from August.
