The maps that the National Weather Service publishes every month, forecasting what may happen in the months to come, predict above-average temperatures and rainfall for much of the United States in May, June, and July. In normal times, that would be unnerving news, a sign of storms coming and a climate wrenched awry. Right now, though, the predictions are fueling a weird hope: that a hotter, wetter summer might put the brakes on Covid-19.

In the temperate zones of the world, other respiratory pathogens, and even other coronaviruses, lose their power as temperatures and humidity rise. But for the coronavirus fueling this pandemic, that remains only a hope. The research showing whether it possesses what virologists call “seasonality” is early, and much of it is contradictory. There is no clear proof yet that summer might save us.
