How to connect?

Michigan City's Lake Michigan Indiana setting features oak, maple, and cottonwood as the main tree pollen sources, with exposure varying between the greener residential areas and the more built-up harbor and commercial corridors along Franklin Street. The Indiana Dunes National Park to the east is a particularly significant local tree pollen source, while the Lake Michigan proximity creates distinct onshore-inland temperature gradients that strongly influence local pollen dispersal.

When is pollen season in Michigan City?
Michigan City's Lake Michigan setting in northwest Indiana produces a season opening in late March with elm and maple before oak peaks through May. Grass from surrounding Indiana farmland peaks through June and July before mugwort and nettle extend exposure into September. The lake proximity moderates temperatures and onshore lake breezes can periodically suppress pollen dispersal throughout the season.
How often is the Michigan City pollen forecast updated?

The Michigan City pollen forecast is updated four times daily. See the timestamp below for the most recent update.

Does pollen in Michigan City come from nearby or far away?

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.

Are pollen levels in Michigan City based on measurements or forecasts?

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 Michigan City, 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.
