Very low today, mostly grass pollen.
Last updated July 20, 2026
Pollen levels in Honolulu remain quiet today. Grass is the only pollen type showing any activity, and it sits at a very low level, meaning most people should have no trouble with it. Tree pollen is absent entirely, so overall conditions are about as mild as they get. Looking ahead, this pattern is expected to hold steady over the next several days, with grass staying at a low, steady level and tree pollen continuing to register as none. This lines up with the typical summer lull for local trees such as swietenia, prosopis, and albizia, which tend to be far more active earlier in the year. For now, sensitive individuals can expect calm conditions with little pollen-related irritation.
