Air at the Prilep station

Prilep, North Macedonia

Network: Ministry of Environment and Physical Planning · Station code: MK0052A

This year, up to yesterday (October 6)

at least

20 days

with a daily average of particulate matter PM10 above the EU limit of 50 µg/m³.

Readings are missing for part of the period, so the real number may be higher.

Worst day: January 25, 2026, PM10 85 µg/m³ as a daily average, 1.7 times the limit.

How the air is changing

Over the last seven days there was more PM10, PM2.5, NO₂, and O₃ in the air than the week before.

  • PM10: average 20.4 µg/m³, week before 13.4 µg/m³
  • PM2.5: average 9.7 µg/m³, week before 7.8 µg/m³
  • NO₂: average 16.1 µg/m³, week before 13.8 µg/m³
  • O₃: average 57.5 µg/m³, week before 44 µg/m³
  • SO₂: average 1.4 µg/m³, week before 1.7 µg/m³

Last month there was less PM10, PM2.5, and O₃ in the air than the month before.

  • PM10: average 18.5 µg/m³, month before 28.2 µg/m³
  • PM2.5: average 10.9 µg/m³, month before 17.5 µg/m³
  • NO₂: average 12.7 µg/m³, month before 12.4 µg/m³

* 2026 up to October 6; the average since the start of the year is not yet an annual average.

The monitoring networks have not yet finally verified this year’s data. The EEA publishes verified values once a year.

≥ means at least: more than a tenth of the days or hours are missing, so the real number may be higher.

² Too few readings to compare with the number allowed: the figure covers only what was measured.

Unverified hourly values of particulate matter from 975 µg/m³ up, and single spikes from 500 µg/m³ up between low values, count as missing. In the verified data for BiH from 2023 to 2025 no hour was above 600 µg/m³.

■ and a figure in red: more than is allowed for the whole year.

The column for 2023 is shown on wider screens.

Compared with the new EU rules and the WHO recommendation

This is not the yardstick for the verdict above, only a comparison. From 2030 the EU tightens its limits (Directive (EU) 2024/2881), and since 2021 the World Health Organization has recommended even lower values.

  • EU from 2030: daily 45 µg/m³, 18 days allowed. In 2023 there were 67 such days.
  • WHO 2021: daily 45 µg/m³, at most three to four days a year. In 2023 there were 67 such days.
  • EU from 2030: annual average 20 µg/m³. Average in 2023: 33 µg/m³.
  • WHO 2021: annual average 15 µg/m³. Average in 2023: 33 µg/m³.

Calculated from the hourly values the EEA publishes. If late values arrive afterwards, an outage gets shorter or disappears.

Where the data comes from

Measured by Ministry of Environment and Physical Planning. We take the values from the European Environment Agency (EEA) under the CC BY 4.0 licence.

Values marked provisional have not been fully checked by the network yet. The EEA publishes verified data for the previous year once a year, usually by the end of September.

An hourly value is the average of one hour. We show the end of the hour: the value to 18:00 was measured from 17:00 to 18:00.

A day runs from midnight to midnight local time.

We only show an average when at least three out of four hours in the period have a reading. The EU air quality directive requires this for daily averages, and we apply the same rule to longer periods. We compare an annual average with the EU limit only once 90 % of hours are measured, as the directive requires. For 12 months and for a year we ask for more: if less than 90 % of hours are measured, every full calendar month needs readings for at least half of its hours. Otherwise a whole season could be missing from the average, such as summer, when ozone is highest.

We do not call a difference of up to 10 % a change, nor one of up to 1 µg/m³ at low levels, because weather and measurement uncertainty alone cause differences that size.

When a station sends no reading, the EEA sometimes fills the hour with a model estimate. We draw those hours dashed and leave them out of every average.

The EU limits come from Directive 2008/50/EC. Here they serve as a yardstick for comparison. When more than a tenth of the days or hours are missing, the number of exceedances can only be higher, so we write “at least” in front of it.
