When visiting Israel during the summer months you will need light clothing – short sleeve shirts, T-shirts, shorts, sandals, beach shoes and a bathing suit. It is wise to have a light sweater or jacket because nights spent in the mountains and desert can be cool.
If visiting Israel during winter, warmer clothes will be necessary - jacket or coat (preferably a raincoat, warm shoes, umbrella, scarf, gloves.
Winter in Israel is not as cold as in Europe but can be quite chilly on rainy days. If you are visiting Eilat or the Dead Sea, remember your bathing suit as even in winter it can be hot enough to swim. Do not forget sunscreen, a hat for protection from the sun and sunglasses, all essential items in all seasons.
When visiting Holy sites modest dress is expected for both men and women - covered shoulders and long trousers or skirt (covering the knees).
