São Luis Ragweed Pollen Count: 5-Day Forecast

Pollen Atlas models the daily detail as an overall index: day-by-day splits by individual pollen type are not part of the modelled data, so this table shows São Luis’s overall trend across the week. Today’s ragweed pollen reading is the headline above.

Species driving São Luis’s ragweed pollen

Species-level counts are not part of the modelled data Pollen Atlas publishes — the modelled index is reported per pollen type, not per species — so this section gives the type summary: ragweed pollen reads 19 (Low) today. The plant-by-plant detail that is available, from the Google Pollen API, is in the next section.

How to read this: the “ragweed” figure on this site is the modelled weed pollen index — the weed group (ragweed + mugwort) — printed under the ragweed name the rankings use.

What this ragweed pollen level means

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

Enjoy outdoor activities.

Weeds — pellitory through the warm months and ragweed in late summer where it has spread — close a long season that can run into November. This month sits inside the ragweed pollen window for the Mediterranean pattern, so today’s ragweed pollen reading should be judged against that chapter of the Portugal year. No Portugal allergy season guide is published yet, so the seasonal context here follows the Mediterranean regional pattern.
