San Jose Tree Pollen Count: 5-Day Forecast

Pollen Atlas models the daily detail as an overall index: day-by-day splits by individual pollen type are not part of the modelled data, so this table shows San Jose’s overall trend across the week. Today’s tree pollen reading is the headline above.

Species driving San Jose’s tree pollen

Species-level counts are not part of the modelled data Pollen Atlas publishes — the modelled index is reported per pollen type, not per species — so this section gives the type summary: tree pollen reads 14 (Low) today. The plant-by-plant detail that is available, from the Google Pollen API, is in the next section.

What this tree pollen level means

Low risk. Keep windows open; consider allergy meds only if sensitive.

Enjoy outdoor activities.

Planted trees open in winter — the juniper family and ash first, mulberry at the heart of spring. This month sits outside the usual tree pollen window for the Desert Southwest pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Arizona allergy season guide singles out mulberry, ash and olive — planted trees, not wild desert flora.
