According to the five-day outlook, grass, artemisia, and cypress pollen levels will increase later in the week.

On 16 July 2026, Grass is the dominant pollen source in Gorinchem. willow, alder, artemisia, birch, hazel, and cypress are not currently active.

January marks the start of Gorinchem's pollen year, led by hazel and alder before birch dominates through to April, with the season closing out in August. Through April and May, oak and ash add to the load, with grass then leading through June and into July. Air movement here is affected by the confluence of the Merwede and Linge rivers, and the fortified old town on the river delta adds a local wrinkle to the Gorinchem pollen picture.

The Gorinchem 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 Gorinchem, 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.
