Red Sea water temperature by month 2026

The Red Sea off Hurghada runs from 21°C (70°F) in February, the coldest month, up to 30°C (86°F) in August, the warmest — a swing of 9°C across the year that decides what you wear in the water and which trip you book. TL;DR • Red sea water temperature by month in 2026 ranges from 21°C (70°F) in February to 30°C (86°F) in August. • The annual average sits near 26°C (79°F), warm enough for snorkeling without a wetsuit from June through October. • December through March is the only stretch where a 3-5mm wetsuit makes a real difference on longer dives. • August and September are the warmest months but also the busiest for boat trips out of Hurghada.
Why this matters
Water temperature is the single biggest variable in how a Red Sea trip actually feels. A diver in a shorty wetsuit in February is cold within 30 minutes; the same diver in August barely needs neoprene at all.
Anyone planning Hurghada snorkeling and diving trips around a specific month should check this table before booking gear or a boat slot — not after landing at the resort and realizing the water is colder than the beach felt.
Red sea water temperature by month
The table below tracks average sea-surface temperature for the Hurghada coast across the year, based on multi-year averaged sea-surface data for the Red Sea. Depth, wind, and distance from shore shift the number a degree or two either way — reef walls at 20 meters run cooler than the shallows where most snorkeling happens.
| Month | Avg water temp (°C) | Avg water temp (°F) | Wetsuit guidance |

| February | 21°C | 70°F | 3-5mm recommended |
| March | 22°C | 72°F | 3mm useful |
