Local Environmental Conditions
The course at Crooked Stick Golf Club, on a wooded parkland course north of Indianapolis in the Carmel area, is shaped by mature oak and maple canopy and native grass roughs, with bentgrass fairways adding further seasonal exposure. Golfers and visitors can expect a pollen pattern broadly in step with the rest of the Carmel area.
Crooked Stick Golf Club tracks Carmel's broader pollen pattern, with maple and elm appearing from March before oak peaks during April. Peak grass pollen arrives in May and June, and ragweed extends the season into September. A humid continental climate drives a sharp spring tree peak and an equally distinct late-summer ragweed run, a defining feature of the local season.

How often is the Carmel pollen forecast updated?

Does pollen in Carmel 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 Carmel 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 Carmel, 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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
