Israel is a country typical of brilliant sunshine, whose amount of sunlight and level of UV radiation are among the highest in the world. Israel is located in an area unique in its bi-seasonal nature: hot, dry summers and cold, rainy winters.
The dry season goes from the beginning of May to the end of October, with the hottest months being July and August. From September to November and April until June, the weather is comfortable; almost no rain falls and visitors can both swim in the sea and travel comfortably in the desert. When visiting Israel in the summer, visitors should come equipped with light clothing and a bathing suit; in winter, bring heavier clothing and an umbrella. Israel enjoys long, warm, dry summers (April-October) and generally mild winters (November-March) with somewhat drier, cooler weather in hilly regions, such as Jerusalem and Safed. Rainfall is relatively heavy in the north and center of the country, with much less in the northern Negev and almost negligible amounts in the southern areas
