Located on the Red Sea coast at the southern tip of the Sinai Peninsula in Egypt, Dahab enjoys a classic desert climate — sunny and dry year-round with minimal rainfall. Summer temperatures (June–August) can soar to 38–45°C, but low humidity (25–32%) keeps the heat more bearable in the shade. Winters (January–February) remain mild with daytime highs of 19–23°C, large daily temperature swings, and only 3–5 rainy days per year concentrated in the colder months. Red Sea water temperatures stay consistently warm — 28–30°C in summer and 21–24°C in winter — making Dahab an ideal year-round destination for diving and water sports.
Dahab Weather by Season
Spring (March–May)
Spring in Dahab is one of the best times to visit, with daytime temperatures gradually climbing from 25°C to 33°C under clear, dry skies. March has the highest chance of rain in the year, but at just 2%, encounters with rainfall are extremely rare. Sea temperatures range from 21–24°C, which may feel slightly cool, but with 10–11 hours of daily sunshine, the conditions are ideal for outdoor activities and snorkeling.
Summer (June–August)
Summer is Dahab’s hottest season, with peak temperatures reaching 38–45°C and occasionally touching 50°C. This is the driest period of the year with near-zero chance of rain and over 12 hours of intense sunshine daily. Despite the extreme heat, low humidity (25–32%) makes shaded areas feel relatively tolerable, and Red Sea water temperatures peak at 28–30°C — perfect for diving and water sports.
Autumn (September–November)
Autumn is another peak travel season in Dahab. Temperatures gradually ease from 33°C in September to a pleasant 24°C by November. Sea temperatures hold steady at 27–28°C, making this arguably the best time for diving. Clear skies, minimal rainfall, and comfortable temperatures create the perfect combination for both sightseeing and underwater adventures.
Winter (December–February)
Winter days in Dahab are mild at 19–23°C, but nights can drop sharply to 6–10°C — so the daily temperature swing is significant. Temperatures never dip below freezing, but a jacket is essential in the evenings, especially when the wind picks up. The few rainy days of the year (3–5 total) fall mostly in this season, and sea temperatures dip to 21–24°C, meaning a wetsuit is highly recommended for divers.
Best Time to Visit Dahab
The best times to visit Dahab are spring (March–May) and autumn (September–November). Both seasons offer comfortable temperatures of 25–33°C with virtually no rain, making them ideal for outdoor activities, diving, and snorkeling.
Among all months, September and October stand out as the sweet spot — sea temperatures are still warm at 27–28°C while the air has cooled down enough for comfortable sightseeing. October is widely considered the single best month to visit Dahab, followed closely by September and the spring months of April and May.
Winter (December–February) is popular with European travelers thanks to its mild daytime warmth, making it great for sightseeing and trekking. However, this is also peak season, so booking flights and accommodation well in advance is strongly advised.
Midsummer (July–August) is tough for outdoor exploration with temperatures exceeding 40–45°C, but it is low season — meaning flights and hotels are significantly cheaper, which can work well for budget-conscious travelers.
