Abstract
A study was carried at Tono irrigation area in the Upper East Region of Ghana to assess the relationship between some selected climatic parameters and their correlation with potential evapotranspiration (PET) estimated using Penman-Monteith method. The selected climatic parameters were temperature, humidity, wind speed and solar radiation. The climatic parameters were sourced at the Tono meteorological station and subjected to statistical analysis using SPSS version 20. PET showed strong positive correlation with temperature (r= +0.9588), solar radiation (r= +0.7185) and windspeed (r= +0.5907) but strong negative with humidity (r= -0.7843). PET was high between the month of November and March which required water to irrigate the major crops in the area. Moreover, rainfall was high between the month of April and October with the highest in August.
