It’d be interesting to see if the warmer weather since Tuesday will reduce the number of new cases. If we assume a week between exposure to getting diagnosed, we would start seeing lowering rate of new infection starting from mid next week.
Weather in Spain in the en of february is cold most fo the times. March is a changeable weather, can have very cold weeks, some few days with 25C and very sunny. But cold also. May will be a hot month.
