Local Environmental Conditions
Tree pollen in Kidwelly Carmarthenshire comes mostly from oak and ash, with parks and mature gardens standing in contrast to the more built-up centre. Grass pollen from surrounding Carmarthenshire fields is significant through the summer months, carried in by the prevailing Atlantic airflow. Overall exposure follows the broader regional trend, moderated somewhat by the town's parks and gardens.
Ask anyone with allergies in Kidwelly Carmarthenshire and they'll tell you it's oak and ash that cause the trouble. Oak pollen typically runs from April to May, with ash picking up between March and May. Then grass pollen takes the baton from May all the way to September, usually peaking in June and July — that's when most people really feel it. Good to know if you're planning anything outdoors that time of year.

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. |
