In the article certain statistical characteristics are analyzed as they are the gusts, the persistence and the conditioned probabilities of days with Condition of Intense Cold. The indicative bioclimatic used Condition of Intense (IFC) Cold is generated starting from the thermal sensations of people in contrasting schedules of the day (7 am and 1 pm), in two modalities, according to the presence or not of the wind. The climatic data came from the meteorological stations of Casablanca and Santiago de las Vegas, representative of the climatic conditions of the territory, in the period 1981-2018. Through the statistical selected characteristics it was possible to obtain additional information enlarged on the behavior and manifestations of the Condition of Intense Cold in the county of Havana, sitting down the bases stops in later investigations to extend their use to other counties of the country. The persistence values ​​of the phenomenon become less appreciable as the gusts increase, which shows that these events are generally limited to periods of a few days. There are high values ​​of persistence of the phenomenon in Havana during the months of December to February, being more likely in the windy CFIs, representative of the worst bioclimatic conditions, although this phenomenon is characteristic of occurring in isolation.
