Sinai Peninsula in March

October through April offers perfect weather for Sinai exploration. Daytime temperatures hover around 25-30°C, ideal for hiking Mount Sinai or exploring desert valleys. Nights can drop to 10°C in winter months, especially at higher elevations around Saint Catherine. The Red Sea maintains comfortable swimming temperatures year-round - around 22°C in winter, perfect for diving and snorkeling. Summer months from May to September bring intense heat, with temperatures often exceeding 40°C inland. Coastal areas remain more bearable thanks to sea breezes, but midday sun becomes punishing. Many desert activities shut down during summer afternoons. December and January see occasional rain in the mountains, which can create flash floods in desert valleys. This rarely affects coastal areas but can impact Mount Sinai climbing conditions. March and November offer the sweet spot - warm days, cool nights, and fewer crowds than peak winter season. Ramadan affects restaurant hours and alcohol availability, so check dates when planning your visit. The holy month moves through the calendar each year.
