This research aims to study the reasons for the variation in annual rainfall in the village of Dhahir al-Fawaris during the period 2015-2025, and to analyze the potential relationship between rainfall and annual temperatures. The research revolves around the following questions: 1. What is the pattern of variation in annual rainfall in the village of Dhahir al-Fawaris during the period 2015–2025? 2. Is there a relationship between the amount of annual rainfall and annual temperatures? 3. What are the possible factors that explain the observed variation in rainfall? To answer these questions, the study relied on monthly and annual climate data extracted from NASA files (NASA POWER) and from recorded measurements of temperatures and rainfall amounts for GLOBE students, extracted from Visualize Data. This data was then statistically processed, converted into annual averages, and displayed in tables and graphs using Microsoft Excel. The observed variation in rainfall amounts was then interpreted. The results showed a significant variation in the amount of annual rainfall between years, with some years recording relatively high amounts, while other years were dry. Annual temperatures also recorded a general increase with slight differences between years. A relative inverse relationship was also observed when comparing rainfall data with annual temperature data The high average annual temperature is associated with low rainfall in most years, with limited exceptions due to exceptional weather conditions. Based on these findings, the researcher recommends raising public awareness about the importance of water conservation during years of low rainfall and encouraging future studies that incorporate other climatic factors such as wind and humidity, and that utilize the research results findings in agricultural and water planning.
