In spring, tree pollen is at its highest. Birch is a major source then. Oak, ash, and pine also release pollen as the weather warms. Grass has not fully started yet, but some early plants may already be active.

From late spring into summer, grass pollen becomes common. This is usually from May to July. Many grasses in fields, gardens, and along paths release pollen. Weed pollen can also begin, including plantain and nettle in warmer weeks.

In late summer and early autumn, weed pollen is more important. Mugwort and nettle are common plants that release pollen then. Levels usually drop as the days grow cooler and shorter. By autumn and winter, pollen in Morfa Nefyn is much lower.
