Claremont sits near the Angeles National Forest and is impacted when regional fires push smoke through the Basin. In practice, this means many people experience:
- Longer commutes through hazy conditions when schools and workplaces remain open but visibility and air quality drop.
- Indoor exposure where smoke infiltration occurs through HVAC systems, open windows, and poorly maintained filters.
- Health impacts that show up quickly—especially for people with asthma, heart conditions, or those who spend time outdoors for work, exercise, or events.
Even when the wildfire is far away, smoke is still measurable. For many residents, the key question becomes not whether smoke was present, but whether the conditions in your daily environment contributed to your specific injury.
