Local Environmental Conditions
The heart of Newcastle Emlyn is surrounded mainly by open grassland, with a good deal of woodland. Of the trees nearby, oak is the one that matters most for allergies. Grass pollen is significant here, and plantain contributes weed pollen. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Oak leads the season in late spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in midsummer, with temperatures around 15°C, and their pollen lingers into early fall. Plantain brings a final peak from late spring into early fall. Rain is heaviest in winter, often giving short breaks from high pollen levels. By early winter, pollen levels are low again.

Are pollen levels in Newcastle Emlyn 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 Newcastle Emlyn, 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.

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. |
