Climatic change is one of the most important issues of present times, therefore, world-wide interest in global warming and climate change has led to numerous trend detection studies. This study focuses on the variability and trends of the monthly, seasonal and annual temperatures in Egypt over the period 1901-2016 (116 years). Variability of temperature has been computed using mean (μ), standard deviation (σ) and coefficient of variation (CV). The Mann-Kendall (MK) test was used to detect the trends of temperature with Sen's slope estimator. One of the main results of this study is the confirmation of the increasing trend of temperatures in Egypt. There was a definite positive trend for the annual temperature over this period with an increase of 0.87℃. Seasonally, the highest warming trends were observed in the summer season with an increase of 1.27 ℃ and the lowest warming trend in the winter season with an increase of 0.46 ℃. There is a clear increasing trend of the temperatures in Egypt for the studied period. This, in turn, will aid in decision-making regarding future funding and establishing research related to climate change in Egypt.
