Tree pollen seasons vary with local climate and vegetation, so this page reports the measured readings first and treats any calendar as background only. No regional calendar is asserted for this area, so today’s tree pollen reading is reported as a modelled index value, without placing this month inside or outside a regional window. No Iran allergy season guide is published yet, so the seasonal context here follows the Global regional pattern.
