Previous research has suggested an involvement of meteorological conditions in the spread of droplet-mediated viral diseases, such as influenza. However, as for the recent novel coronavirus, few studies have discussed systematically about the role of daily weather in the epidemic transmission of the virus.

Findings highlight that temperature and humidity related variables are negatively correlated to the virus transmission, whereas air pollution (PM2.5) shows a positive correlation (at lesser degree). In other words, COVID-19 pandemic transmission prefers dry and cool environmental conditions, as well as polluted air. For those reasons, the virus might easier spread in unfiltered air-conditioned indoor environments. Those results will be supporting decision makers to contain new possible outbreaks. https://www.nature.com/articles/s41598-020-73197-8
Studies on coronavirus outbreaks put in evidence how the meteorological conditions are a co-factor in transmitting the virus transmission, enhancing or suppressing it. The atmospheric variables, i.e., ambient temperature and humidity, or the solar irradiation act differently with respect to the coronavirus survival, e.g.,4,5 show that the coronavirus transmission is facilitated in cold and dry weather https://www.nature.com/articles/s41598-020-73197-8
Environmental conditions affect the stability of severe acute respiratory syndrome coronavirus 2 in nasal mucus and sputum. The virus is more stable at low-temperature and low-humidity conditions, whereas warmer temperature and higher humidity shortened half-life. https://wwwnc.cdc.gov/eid/article/26/9/20-2267_article#:~:text=We%20found%20that%20environmental%20conditions,shortened%20half%2Dlife.
I have seen over the years, that at the start of rainy season or at the end of rainy season many people get flu, this means that flu and even COVID-19 is related to weather. When we inhale dust during dry season after rain many people get the flu.
