Gulf Islands pollen forecast - today, tomorrow and the week ahead

On 30 August 2026, overall pollen levels in Gulf Islands are high. Grass is the main contributor to airborne pollen, while artemisia and ambrosia remain at lower levels

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

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

On 30 August 2026, Grass is the dominant pollen source in Gulf Islands. artemisia and ambrosia are also present but at lower levels. cypress are not currently active.

Gulf Islands National Seashore's pollen season lines up with the rest of Gulf Islands, starting with oak and pine in January then cypress follows, running through February. Rather than one sharp peak, grass pollen stays elevated across most months, and mold levels also stay elevated for much of the year. Florida's subtropical climate means there is no sharp winter break in the pollen calendar, consistent with the wider Gulf Islands area.

The Gulf Islands 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 Gulf Islands, 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.
