Pollen count Delta residents check each morning

The Delta pollen count today is 10 (Low). The main driver is Ragweed, with weed pollen at 11 today. That total sits on a narrow base: weed pollen is 11 while tree pollen is just 10 and grass pollen 0.6. Plant-by-plant detail for Delta, BC follows, along with the outlook for the days ahead. Pollen Atlas updated this count on Friday, November 6, 2026.

A Low band on the Pollen Atlas index means the Total Pollen Index has stayed in the lower part of the 0–100 scale. Readings in this band are built from low individual category values rather than from one large spike, and the category split above matters more than the headline number: a low total can still contain one category, such as weed pollen or mold, reading noticeably higher than the rest, which is why the split is printed on every Delta page.

In the Pacific Northwest, the main outdoor pollen activity is concentrated in spring and early summer — trees first, then grasses — and readings outside that window are commonly low across every category. Cool-season pages in this region are therefore often defined by what is absent: zero or near-zero tree and grass values, with any remaining total carried by small weed or mold readings. That quiet pattern is itself useful information, and it is reported here exactly as modelled.

To see whether today’s pollen level holds, check the 5-day Delta pollen forecast below — it is currently mixed, with Monday the highest day in the window.

This is the pollen count Delta residents check each morning, built from the day’s tree, grass, weed and mold readings.

What is the Delta pollen count today?

The Delta pollen count today is 10 out of 100 (Low) on the Pollen Atlas Total Pollen Index, driven mainly by Ragweed.

Short answer for anyone searching pollen count today Delta: this page is updated every morning with the day’s modelled reading.

Delta allergies today

Delta allergies today are set by the same reading as the pollen count above: the Total Pollen Index is 10 (Low), driven mainly by Ragweed. When people ask about Delta allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Delta.

Allergies in Delta follow the British Columbia calendar set out below — the chapters, the plants behind them, and the 5-day forecast on this page show whether today is typical for the season or an exception to it. If you are checking allergies today in Delta before heading outdoors, the split at the top of this page is the part to read: it shows which pollen is doing the work today, not just how high the total sits.

Read the five-day table on this page as the Delta allergy forecast: today reads 10 (Low), and the day-by-day outlook shows whether Delta allergies are set to ease or build across the week — the days to plan outdoor time around are the ones where the index steps down, not just today.

In practice, the allergy count Delta today records is this same combined reading — tree, grass, weed and mold in one index.

The Delta allergy count today is 10 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Delta

What is driving Delta’s pollen today

The shape of today’s 10 (Low) is set by weed pollen at 11 (Low on its own scale) — about 51% of the four category readings added together, 1 points clear of the next category, tree pollen at 10. A weed-led total is the classic late-year shape: tree and grass pollen have usually receded, leaving weed pollen — and on damp days mold — to make up most of what the index records. Weed pollen leading in November runs against the usual calendar — the British Columbia weed chapter runs August to September — so today’s lead is the model outranking the pattern, and this page reports the modelled reading first.

Plant-level detail is not in today’s feed for Delta, so the drivers have to be read from the category split above — it shows how much of today’s total each category is actually carrying, and plant detail returns here automatically on any day the feed includes it.

Across the five-day window the Total Pollen Index runs from 9 to 26, never changing band. Today’s 10 sits 4 points below the window’s average of 14.2 — a moving window, worth reading day by day rather than from the average.

Plants affecting Delta now

Detailed plant-by-plant readings for Delta were not returned in today\u2019s source data, so this section summarises the pollen types the index above is built from instead of listing individual plants.

Tree pollen is one of the categories with a non-zero reading today, at 10 (Low).

Grass pollen is one of the categories with a non-zero reading today, at 0.6 (Low).

Weed pollen is one of the categories with a non-zero reading today, at 11 (Low).

In the Pacific Northwest pattern, the plants that typically shape this city’s year are spring trees and late-spring grasses in the Pacific Northwest pattern — named here as regional context only, not as today\u2019s measurements.

Delta pollen through the year

Chapter by chapter, the Delta pollen year runs like this:

  • Alder and hazelnut can start in January west of the Cascades, with maple and oak following through April and May.
  • Grasses run from May, peaking in late spring and early summer.
  • Weeds are the minor act — sagebrush and tumbleweed east of the Cascades carry into September.
  • Mold is the wet-season constant west of the Cascades, where rain crashes counts and the season restarts on the first dry, mild day.

No British Columbia allergy season guide is published yet, so this page does not single out signature pollens for Delta — the calendar above is the Pacific Northwest regional pattern, and the plant detail on this page names what today’s feed actually records.

November falls between the main chapters of the British Columbia pollen year — the tail of one and the approach of the next — so the calendar alone explains little today, and the modelled split above carries the story. Between them, the three chapters cover 9 months of the British Columbia year, January to September — leaving a quiet gap of roughly 3 months in the depth of the off-season. No British Columbia allergy season guide is published yet — this calendar follows the Pacific Northwest regional pattern. See Delta pollen count rankings and Delta on the pollen heatmap.

How to read this index

Pollen Atlas reports the Delta pollen count on a Total Pollen Index from 0 to 100, built from separate tree, grass and weed readings. The total is a summary, not an average of the three: a single strong category can lift it, and three quiet categories can hold it down whatever the month. Index values are a modelled pollen risk index computed by Pollen Atlas from open weather, vegetation and phenology data, calibrated against CDC/NAB season data, with plant detail by the Google Pollen API. The index is a modelled 0–100 scale, not a measured count, and figures update through the day, so a morning and an evening visit to this page can legitimately show different numbers.

Delta in today’s US & Canada picture

At 10 (Low), Delta ranks joint 78620th of the 90896 cities Pollen Atlas tracks today — in the middle of the combined US & Canada table. The highest reading on the combined table today is Serpa, Portugal at 53, and the lowest is Galiakberovo, Russia at 5. The whole table spans 48 points today — a wide-open day, when the top and bottom of the table are effectively in different seasons.

Around Delta: Surrey, BC (8 miles away) reads 9 (Low); Richmond, BC (8 miles away) reads 12 (Low); Point Roberts, WA (9 miles away) reads 8 (Low). Delta reads 1 point higher than its nearest tracked neighbour today. Across British Columbia’s 15 tracked cities, today runs from 5 in Kelowna to 12 in Richmond.

Pollen totals are population numbers; symptoms are personal. The same reading can leave one Delta resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every season, allergists in Delta, BC can test whether tree, grass, weed or mold is the category that matters for you — the four readings at the top of this page are the starting point for that conversation.
