Mentor pollen forecast — Lone Star neighborhood

On 9 August 2026, overall pollen levels in Mentor are moderate. Ambrosia is the main contributor to airborne pollen, while artemisia and grass remain at lower levels

On 10 August 2026, pollen conditions in Mentor will be similar to today, with ambrosia at medium levels, artemisia at low levels, grass at low levels

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

On 9 August 2026, Ambrosia is the dominant pollen source in Mentor. artemisia and grass are also present but at lower levels. cypress are not currently active.

Water-edge hazel and willow are usually the first allergenic trees active here, hitting its peak before most trees have even budded, around late winter into March. Oak and birch in the woodland come next, through the heart of spring, cresting around April and May in the year's sharpest tree-pollen spike. Late spring sees grass pollen build steadily toward a peak in June, and ragweed later takes the lead from mid-August through October.

The Mentor 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 Mentor, 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.
