Mean of 4 sensors from AirGradient, readings from 23:47–23:48 local time (21:47–21:48 UTC), summary prepared at 00:00 local time. Median: 4.2 µg/m³; range across sensors: 3.7–17.5 µg/m³.
In Richards Bay the air is good 🟢 AQI 41. Lower than three hours ago. ☀️ +21 °C · No precipitation · Wind 3 m/s
In Richards Bay the air is good right now (approximate, US EPA scale). From 11:00 to 00:00 local time the city mean PM2.5 rose from 5.0 to 7.4 µg/m³. The highest hour was 19:00 with 17.0 µg/m³.
High humidity (88%) possibly makes optical sensors read somewhat higher.
Weather now: clear, 21°C, wind 3 m/s, humidity 88%. By 07:00 the wind is expected to pick up to 5 m/s, which may clear the air. By 11:00 the temperature will be about 25°C.

Daily mean PM2.5 on November 10, 2026 (00:00–24:00 UTC = 02:00–02:00 UTC+2): 5 µg/m³ from 4 sensors that passed the quality check — the same value as in the Atmy Data Hub. No. 4 of 4 cities in South Africa and No. 628 of 676 worldwide, from the most polluted.
Right now in Richards Bay, PM2.5 averages 7.4 µg/m³ — “good” on the US EPA scale (approximate, from hourly readings). Mean of 4 sensors from AirGradient, readings from 23:47–23:48 local time (21:47–21:48 UTC), summary prepared at 00:00 local time. Median: 4.2 µg/m³; range across sensors: 3.7–17.5 µg/m³.
The current level is “good” (US EPA scale, approximate). Air quality is satisfactory; no restrictions are recommended. This is the standard guidance of the scale, not medical advice.
Highest current reading: 17.5 µg/m³ (eSikhaleni, KZN, ZA.). Lowest: 3.7 µg/m³ (Meerensee, KZN, ZA.). The list shows every sensor, highest first.
From Atmy sensors and connected public networks (citizen, experimental and government monitors), aggregated by Atmy. Values are approximate; see the methodology.
The summary is rebuilt every 15 minutes from the latest reading of each sensor, each no older than one hour.
Over the last 364 days with data, the mean daily PM2.5 in Richards Bay was 12.0 µg/m³ — 2.4 times the WHO annual guideline (5 µg/m³). Over the last 30 days: 9.3 µg/m³. From Atmy's archive of daily city means.
In Atmy's daily archive, the cleanest month of the last year was December 2025: 5.3 µg/m³ on average.
The most polluted month of the last year was July 2026: 26.1 µg/m³ on average.
From November to March the mean daily PM2.5 was 6.4 µg/m³, from June to August 20.3 µg/m³ (last 365 days).
The daily value is the Data Hub’s: the mean of the city’s sensors that passed the nightly quality check, each with at least 12 valid hours, and only with sensors at four places 500 m apart; days are UTC.
“Now” uses the same sensors and rule: the mean of their latest readings, each at most 60 minutes old, shown only with sensors at four places 500 m apart reporting.
