April is when the Greek islands shake off winter and the Aegean light returns, when Cyprus hits its first warm beach days, and when Egypt's Red Sea coast becomes one of the most reliable warm-water destinations on the planet. Southeast Asia gets seriously hot in April, with Thailand topping 35 C inland, so the smarter choice is to follow the Mediterranean as it warms up. The Canary Islands are still excellent. Morocco's Atlantic coast around Essaouira finally turns swimmable for the brave.
The weather, the water, the feel
Greek islands run 22 to 25 C air, 18 to 20 C water on the south Aegean. Cyprus pushes 25 C with water around 20 C. The Red Sea around Marsa Alam stays at 24 C water and 30 C air. Bali is still warm and reasonably dry. The southeastern Mediterranean light in April has that particular clarity that photographers chase.
The Red Sea is the standout. Water around Marsa Alam, Dahab, and El Quseir is bath warm with visibility past 30 meters. Greek south coast bays on Crete, Karpathos, and Rhodes start to feel summery by mid-month. Cyprus beaches around Ayia Napa and the Akamas Peninsula warm fast because of the shallow shelf.

Insider planning tips
- Greek Easter shifts every year. If it falls in your window, expect closures and crowded ferries on the long weekend.
- Red Sea diving in April is the year's best, especially the southern sites around Wadi Gimal and Elphinstone.
- Cyprus rental cars are cheap and the island is small. Base in Paphos or Polis to access Akamas easily.
- Morocco's Essaouira is windy. Always. Plan kite gear, not snorkeling, if you go in April.
Where to stay
Greek island studios in Naxos around Mikri Vigla and Plaka are open and half-priced compared to July. Cyprus has good villa stock around Polis on the Akamas side, quieter than Paphos itself. Red Sea resorts in Marsa Alam are at low season rates with the same water. Morocco riads in Essaouira's medina cost a fraction of Marrakech equivalents. The Canaries are reliably affordable in April.
Final word
April rewards the traveler who reads the long-range forecast and books late. Mediterranean weather is moodier this early but the rewards are big when it lands right.
