In March and April, olive trees release a lot of pollen. This makes the air yellow. Many people stay indoors on windy days. Pollen counts are high then.

In May and June, grass pollen fills the air. People with problems avoid going outside. Trees like oak and pine also release pollen. It's a challenging time.

By July and August, pollen counts decrease. The air is still warm. Some plants like ragweed release pollen. But levels are generally lower than in spring.
