Halden 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 Halden’s overall trend across the week. Today’s ragweed pollen reading is the headline above.

Species driving Halden’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 41 (Moderate) 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

Moderate risk. If you have allergies, consider meds and limit exposure during peak hours.

Keep windows closed at midday; shower after being outside.

Mugwort runs through August, and ragweed is scarce at these latitudes — the late window is short and light. This month sits outside the usual ragweed pollen window for the Nordic & Baltic North pattern, so today’s ragweed pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. No Norway allergy season guide is published yet, so the seasonal context here follows the Nordic & Baltic North regional pattern.
