Sewage smell really causing me problems where I live

It's currently some of the warmest days of the year, and for some reason they chose this time of the year to whiff the sewage smell from across the land. It's too warm to close the windows, and I can't afford the necessary components to install AC, so what do I do to cover up the smell? I'm a bit stuck here... it's really stressing me out, I've got sensory issues as well
