In general the oleh can expect long hot and dry summers, and variable winter weather patterns. It is best to find a region in Israel more suited for one’s own temperament. The Jordan Valley and the South of Israel are regions known for extreme heat wave patterns. The Central Hill country also known as the Shomron, may suit those seeking a more endurable summer heat. However, weather norms can be volatile, but usually over a period of days rather than any prolonged duration.
