Moorhead pollen forecast - today, tomorrow and the week ahead

On 30 August 2026, overall pollen levels in Moorhead are high. Ambrosia is the main contributor to airborne pollen, while grass and artemisia remain at lower levels

On 31 August 2026, pollen conditions in Moorhead will be similar to today, with ambrosia at high levels, artemisia at low levels, grass at moderate levels

According to the five-day outlook, ambrosia and grass pollen levels are expected to gradually decrease, while artemisia pollen will increase, suggesting mixed conditions later in the week.

On 30 August 2026, Ambrosia is the dominant pollen source in Moorhead. grass and artemisia are also present but at lower levels. cypress are not currently active.

At Moorhead, near the bank, hazel and willow lead the seasonal calendar, topping out well before most other trees start releasing pollen, around February and March. Late spring brings rising grass pollen that crests in June, then yields to ragweed, the dominant late-summer and fall allergen through October. The overall order of species tends to hold steady, even as exact dates shift slightly each year.

The Moorhead pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Moorhead, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
