LA in Boston?

Much of this year's spring was in fact springlike, cool and cloudy, reminding me of San Francisco. It was a bit weird, but I was happy.

Recently it has been hot and humid. Today it is hot and dry -- 30 C, 42% humidity, 12 C dew point. It feels a bit like LA. Going for a run had my lungs feeling odd... maybe like LA? And there's an odd slightly burned smell to the air, maybe ozone? Though wunderground says the air quality is good. Fire hazard warning, maybe it's just smoke I'm smelling. Which would also be like LA, much of the time... I haven't heard of any ongoing fires, but an auto shop had "heavy" fire last night.

Also, it's bright. Even when in full building shadow, looking out kind of hurt my eyes, and the shadows themselves don't look that dark. I was reminded of "LA light", a result I think of natural and manmade smog diffusing light around. Granted, I haven't been paying that much attention to noon[1] sun and shadows, so I'm not sure what's normal. But it felt different.

[1] 1:30 actually, but that's 12:30 solar time thanks to DST. So pretty close to zenith.
