Spring Pollen Peak: When Are Levels Highest During the Day?

Common Daily Patterns

Tree pollen is mostly released in spring. On clear, dry, windy days, it is more easily stirred up and stays in the air longer. During the day, levels are often relatively higher from early morning to mid-morning and around late afternoon. Short-term changes before and after afternoon thunderstorms can also be noticeable. The exact pattern depends on tree species, region, and weather. It is a good idea to follow pollen monitoring information from local weather and environmental agencies.

How to Plan Outings

• Check the daily level forecast. When levels are high, cut back on unnecessary time outdoors.
• Schedule outdoor exercise like running and cycling after rain or during times when levels are lower.
• If you must go out, wear a mask that fits your face well, and add goggles if needed.
• After getting home, change your outer clothes, wash your face, and rinse your nose to reduce bringing pollen indoors.

Don't Just Look at the "Season"

Many people think they are safe once the flowering period is over. In fact, weed pollen in autumn can also cause clear symptoms in sensitive people. What really helps is keeping a symptom calendar: which months, which weather, and which activities make symptoms worse. This information is very helpful for your doctor when you see them.
