Aurora is enjoying a quiet stretch when it comes to pollen today. Tree pollen, the only category with a reading, is sitting at essentially none, so anyone sensitive to trees like ash, elm, oak, maple, or celtis should find the air pretty easy to breathe this time of year. Looking ahead, tree pollen is expected to stay low through the coming days, which fits the season well. The main tree pollen push typically happens back in spring, so by late July those trees are largely finished releasing pollen for the year. If you do notice symptoms this time of season, grasses or early weeds are more likely culprits than the trees named above, though today's numbers suggest a calm period overall.
