Your question needs clarification. Watching where you are going. In Sharm and in Hurghada there are areas where there will be a strong wind, and there are relatively "warm" regions. The same with the shore strip. If a hotel with shallow water and a long pontoon, then you will be uniquely cool. In any case, you will need windbreaker in the evenings. With a warmer clothes, I can not tell you anything, since I do not know which region you are going to.

For medicines. If you take a tour at an agency, then the medical insurance is included in the package. But, if you need medicine prescribed by your doctor, you must take them. For the first time in Egypt, as in any other region, you may have problems with digestion (another microflora, type of food, water, etc.). Therefore, take funds from a stomach disorder.

And the luggage of the holidaymaker is the same in all countries. There should be a swimsuit and slates at the minimum.
