I can ride my bike to work as its about 10k away, but it's so damn hot im sure I'll get heat exhaustion before I get there. In May there was a heat advisory and basically told people, unless you have to, stay indoors after 10. The only way to be outside is in the shade in front of a fan drinking something cold.
Plus, riding your bike while the air quality is at "concerning" levels just doesn't seem like the ideal solution. You screw up your lungs to make a teaspoon of a difference while every factory in the area keeps churning out buckets of pollution.
North of 95F your body will start having trouble regulating temperature and hydration, ventilation, and shade become critical. On a bike you can only reasonably control hydration (can't depend on strong wind, moving at a constant speed, or staying under building and foliage shade) so basically 9 months of the year you're putting your health at risk to commute by bike. Riding a bike to the nearest bus stop and going from there might be the best middle ground.
