Summer weather could help fight coronavirus spread but won’t halt the pandemic

New research has bolstered the hypothesis that summer’s heat, humidity, abundant sunshine and opportunities for people to get outside should combine to inhibit — though certainly not halt — the spread of the coronavirus.

But infectious-disease experts add a cautionary note: Any benefit from summer conditions would probably be lost if people mistakenly believe the virus can’t spread in warm weather and abandon efforts that limit infections, such as social distancing.
