Abstract


This study analyzed the climate variability trends in Bahati Sub-County, Kenya for the period 1985 to 2015.The climate parameters used included rainfall onset, rainfall cessations, seasonal rain, annual rainfall, annual mean temperature, maximum and minimum temperature. Data on rainfall and temperature was collected from Nakuru Meteorological Station. The strength and direction of the relationship between rainfall and temperature was determined using SPSS software version 23 (correlation analysis) and Microsoft Office Excel 2010 to generate frequency tables, pie charts, graphs and moving averages. The findings revealed that there is a significant, negative and strong relationship between annual rainfall trend and maximum temperature (r= -0.716, p = 0.000). However, the study findings also revealed that the relationship between annual rainfall and minimum temperature had an insignificant, weak and negative relationship (r= 0.151, p= 0.418).
