The best time to visit Oman

Wadis, forts and an empty desert interior — the Gulf without the skyline, and unbearable in high summer. Daytime highs in Oman run from about 24 °C in January to 38 °C in June, an annual range of roughly 15 °C.

Measured against a hiking trip, the conditions hold up January. January is the most consistent single month: highs near 24 °C, nights around 14 °C, and roughly 7 mm of rain across the month.

The binding constraint here is temperature — that is what rules months out, not any composite judgement. February is the weakest month on these criteria.

December sit just outside the window — part of the month works and part does not. These are usually the interesting weeks: conditions are close to the peak-season answer while prices and crowds are not. The map lets you check them fortnight by fortnight rather than trusting a monthly average.

What Oman is known for

Jebel Shams, about 3,000 m, overlooks a canyon often called the Grand Canyon of Arabia
Nizwa's round fort and Friday livestock market are the centre of the old interior imamate
Green turtles nest year-round at Ras al Jinz near Sur, one of the largest such sites in the Indian Ocean
Wadi Shab and Wadi Bani Khalid hold swimmable freshwater pools between desert walls
Salalah, far south, gets the khareef monsoon and turns green while the rest of the country bakes

Ticked rows are months where every hard requirement for a hiking trip is met across at least half the month.

Each row applies that trip type's own hard limits to the same climate data.

Nearby regions

Figures are 30-year climatology sampled at Muscat, Nizwa, Sur, Jebel Shams and Wahiba Sands, averaged across those locations, from ERA5-Land reanalysis fitted with a harmonic seasonal cycle and a trend term, evaluated for 2026. Sampling named towns rather than averaging the whole region avoids blending valley and mountain conditions into a figure true of neither. Cells are about 0.08° wide, from ERA5-Land's 0.1° grid, which is itself driven by a 0.25° (~28 km) atmospheric reanalysis — so individual valleys, sheltered bays and single summits are not resolved. In steep terrain read these as conditions for the wider area rather than for one village. They describe typical conditions, not a forecast. Read how the climatology is built.
