Honey locust
Gleditsia triacanthos
Very low today, mostly grass pollen.
Last updated July 20, 2026
Pollen levels around Columbus are quiet today. Tree pollen is essentially absent, and grass pollen is running very low, so most people should be able to spend time outdoors without much irritation. If you tend to be sensitive to grass, you might notice a faint effect, but for the majority this is a low-concern day. Looking ahead, conditions are expected to hold steady over the next few days, with grass pollen staying at a similarly low level and tree pollen remaining a non-issue. This fits the seasonal pattern for midsummer: trees like honeylocust, linden, maple, and plane finished their main pollen release back in spring, and grasses are now past their peak as well. With ragweed season still weeks away, this is typically one of the calmer stretches of the year for allergy sufferers in the area.
