Species driving Castelo Branco’s tree pollen

What this tree pollen level means
Moderate risk. If you have allergies, consider meds and limit exposure during peak hours.
Keep windows closed at midday; shower after being outside.
Cypress opens the year in winter, hazel and alder follow early, and olive carries the spring peak from April into May. This month sits outside the usual tree pollen window for the Mediterranean pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. No Portugal allergy season guide is published yet, so the seasonal context here follows the Mediterranean regional pattern.
