Spring
Spring in Muscat is the kind outdoor season: March, April and May. Days are useful. The fiercest heat has not landed yet. This is walking weather if you keep midday in mind.
In Muscat the meteorological summer is June, July and August and winter is December, January and February. Evenings can still bite. A layer earns its place. Do not assume Muscat in these months is already the hot-season grind.
Read Muscat in this stretch as its own climate, not as a generic holiday season copied from another destination.
