About pollen in San Diego

Tree pollen is the more active category around San Diego today, though it remains at a low level overall, so most people should get through the day without much irritation. Grass pollen is barely registering, sitting at a very low level. Trees such as jacaranda, podocarpus, cupaniopsis, silver palm, and syzygium are the main local contributors, but current amounts are mild enough that only those with heightened sensitivity are likely to notice any effect. Looking ahead, conditions are expected to hold steady over the next few days, with grass pollen staying at a consistently very low level and no significant swings anticipated. This fits the seasonal pattern for midsummer in San Diego, where the spring tree pollen surge has largely faded and grass pollen tends to stay subdued through this stretch. Overall, allergy sufferers should find this a relatively calm period, with no major changes on the horizon.
