According to the five-day outlook, cypress and grass pollen levels are expected to gradually decrease, suggesting improving conditions later in the week.

On 25 June 2026, Grass is the dominant pollen source in Islington. alder, birch, hazel, cypress, and willow are not currently active.

Islington's pollen season opens with hazel and alder from late January, benefiting from London's mild urban climate. Plane and birch follow through April and May, with grass pollen peaking through June and July. The dense urban environment limits local vegetation, meaning exposure is largely driven by pollen carried in from the royal parks and greener parts of London, with the dry southeast climate providing fewer rainfall interruptions than in northern and western UK.

The Islington 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 Islington, 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.
