The impact of climate change on global agricultural production requires no emphasis. Nigeria, in recent times have had her own share of climate change impacts of which her agricultural sector is majorly affected. The location of the country along low-lying coastal lines makes it vulnerable to climate change. This is further worsening her state food insecurity. In lieu of this, greenhouse farming was contemplated among other possible alternatives to farming in a changing climate. However, construction materials that will generate the desired greenhouse conditions at minimum cost is of great importance. In order to efficiently maximize the use of greenhouses, this study was conducted to analyse climatic factors influencing greenhouses in Ibadan, Nigeria and to recommend suitable glazing materials. Data on climatic parameters were obtained from three relevant sources (international institute of tropical agriculture, Ibadan; Nigeria Institute of Meteorology and Department of Geography, University of Ibadan, Nigeria). The data covered a span of 32 years. These data were subjected to inferential statistical techniques to ascertain the level of deviation that has taken place. A model greenhouse was used in the study. The highest value of temperature and solar radiation recorded in the 32 year period was also used in the thermal equations. The results showed that temperature has been consistent in Ibadan and the most suitable glazing material for Ibadan is high-density corrugated polyethylene.
