Lisbon pollen forecast — Royal Obidos Spa & Golf Resort – Championship Course neighborhood

On 21 July 2026, overall pollen levels in Lisbon are low. Artemisia is the main contributor to airborne pollen, while grass remain at lower levels

On 22 July 2026, pollen conditions in Lisbon will be similar to today with no significant pollen expected.

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

On 21 July 2026, Artemisia is the dominant pollen source in Lisbon. grass are also present but at lower levels. alder, birch, hazel, cypress, and willow are not currently active.

Pine and Mediterranean scrub pollen peak in February and March around Óbidos, a few weeks in step with the neighbouring Silver Coast courses. The inland setting sees slightly less wind dispersal than the coast, though dry summer conditions from May still keep pollen levels low.

The Lisbon 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 Lisbon, 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.
