May and June are the worse months to visit Oman : in the north, heat is suffocating (and very humid on the coast) and the sun reaches the zenith at noon (we are on the tropic of Cancer), so even the northern expositions are not spared. In the South, before the monsoon starts the heat is strong and hunidity is at its maximum : it is hardly bearable. High mountains like Jebel Shams and Jebel Akhdar are a bit more fresh though…
It’s the season for mangos (mainly sold green) and early date strains start to be harvested and consumed fresh.
Below is a summary of the weather in the main climate zones of Oman.
The markers 🟢🟡🟠🔴 show our opinon (subjective, but based on objective facts) regarding the possibilities for hiking and camping.

* in the desert (above all Rub Al Khali, and to a lesser extent in Wahiba Sands), temperatures rise higher during the day, and drop lower at night (~5-10° gap, sometimes more).
Bad weather in Northern Oman bring sudden drop in temperatures inland.
** in the montains, above all in winter (when the sun is lower), there can be big difference between northern slopes, which see less sun, and southern slopes which are continuously exposed. The same apply to steep-sided places.
According to us, in the north, the only possible (thus particularly pleasant) outdoor activity is aquatic hiking and canyoning (which we do without wetsuits, wearing shorts and t-shirts) : we spend the full day in the water while it’s more than 40°C outside!
It’s the high season for green turtles to lay eggs, which one can watch at the marine reserve of Ras Al Jinz. In summer, up to 200 turtles might come same night on the same beach to lay eggs!
Season for kitesurfing and windsurfing is starting (until early September) on the coast of the Indian Ocean (between Ras Al Had and Shuwaymiyah).
In the Sea of Oman, summer is the best season for diving because of a better visibility.
Northern Oman, it’s too hot for mountain hiking, camping in the lowlands (even higher in the mountains, we can’t really say it’s fresh…), spending a full day at the beach, and obviously for going in the desert…
We do not have group tours scheduled during this time of the year.
However, we can organise for you, on-demand, a tailor-made tour with canyoning and aquatic hiking and maybe also turtle watching and half-day snorkeling .

We do not offer kitesurfing nor diving activities…
