Model vs measured
The nearest measured PM2.5 reading is 7.7 µg/m³ from Sensor.Community (median of 4 sensors), centred about 5 km from the city centre. That is 10.6 µg/m³ below the model estimate of 18 µg/m³. Low-cost sensors can read high in humid air; reference monitors are more accurate but sparser.
Wildfire smoke
PM2.5 is forecast to reach 35 µg/m³ in the next 24 hours while NASA satellites detected 24 fire hotspots within 300 km in the last day (nearest about 83 km away). Smoke is a likely contributor: keep windows closed, run an air purifier or HVAC filter, and check the fire map before heading out.
Advice for sensitive groups
At 62, most people are fine outdoors. If you are unusually sensitive to PM2.5, keep long or intense workouts to the cleaner hours shown above.
