Species driving Chelas’s grass pollen

The modelled data reports grass as one combined index — there is no species-by-species split for grass anywhere in the data, so this page does not invent one. Today’s modelled grass index for Chelas is 2 (Low), and the 5-day overall trend above shows the shape of the week.

As regional context only — not as today’s readings — in the Mediterranean pattern, the plants that typically shape this city’s year are winter cypress and early hazel, spring grasses and olive, and late-summer weeds spread across a long, mild season.

What this grass pollen level means

Low risk. Keep windows open; consider allergy meds only if sensitive.

Enjoy outdoor activities.

Grasses build from spring and peak from April into June, earlier in the south. This month sits outside the usual grass pollen window for the Mediterranean pattern, so today’s grass 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.
