Isohyets are similar to both isobars and isotachs in many way except that isohyets join equal values of rainfall in a given period. The map above shows isohyets for rainfall in a month during July of 2008. The intervals are in 100 mm bands. These maps give a clear indication of the distribution and intensity of rain across the entire region and this map gives us an idea of the distribution of rainfall in the region.
