The spatial distribution of Erythemal Ultraviolet Dose Rate (EUV) at noon in mW/m2 observations gotten from the Ozone Monitoring Instrument (OMI) are presented over Egypt covering the geographical domain (22.5°–31.5°N, 25.5°–35.5°E) during twelve  year from 2005 to 2016. With the end goal of mapping contour, with a spatial resolution of 1°×1° the results illustrated by monthly, seasonally and all period contour maps indicate high similarity of EUV in all years. Monthly correlation (R2) relationship between EUV and Latitude also estimated in simple linear form. High R2 was found in December and January (97%) were low one was found in July (53%). In the frame of the variability, Egypt was considered as an average area; the box-whisker plots were created for average monthly and annual values of EUV. The monthly mean of EUV values are lower in the winter months (December to February) 116.17±2.30 mW/m2 compared to those in the summer months (June to August) 282.36±2.87 mW/m2. The annual mean of EUV values are lower in 2015 (204.15±60.41 mW/m2) and higher in 2013 (213.13±60.34 mW/m2).
