Very High Pollen in Spring Valley, NV

About pollen in Spring Valley

Tree pollen is dominating the air in Spring Valley today, reaching a very high level that is likely to affect even those with mild sensitivities. Ash, oak, pine, pistacia, and celtis trees are the main contributors, and anyone prone to sniffling, itchy eyes, or congestion should expect a rough day. Weed pollen, by contrast, remains very low and should not add much to the overall discomfort. Looking ahead, tree pollen is expected to stay elevated over the next several days, so relief is not on the immediate horizon. This is a bit later than the typical spring peak for trees, but warm, dry conditions in the desert Southwest can keep certain species like ash and pine active well into summer. Weed pollen should remain quiet through this stretch, with the more familiar late-summer and fall ragweed season still to come.

What to do today

• Pollen is very high today; stay indoors when you can, especially midday and afternoon.
• Keep windows closed and run air on recirculate.
• Shower and change clothes right after coming inside.
• Consider allergy medication, and see a clinician if symptoms are severe.
