Traveller notes on Ras Al Khaimah in May
Notes from nearby Dubai (102 km away)
Ras Al Khaimah doesn't have its own notes for May yet — these are about Dubai, close enough to share the season.
May is when Dubai stops being a comfortable winter destination. The forum's figure is "mid to high 30s, if not tipping 40 in the day and down to mid 20s during the hours of darkness — and those are shade temps," a distinction worth taking literally in a city with a lot of unshaded pavement. Whether that's fine depends on who you're with: one parent's two-year-old "did struggle at times during the day" on a late-May trip, and her advice was to book a hotel pool with plenty of shade rather than skip the season. The structural point posters make is that Dubai is built for it — indoor spaces of any size are air-conditioned and pools are chilled. Our record has 39°C highs, 24.6 kph average wind and effectively no rain, with sea already at 29.6°C.
Other months in Ras Al Khaimah
Ras Al Khaimah's forum calls early March a great time to visit — low-to-mid 30s°C with clear sunshine most days and a warm sea, cooling into the low 20s at night, comfortable for dining outdoors. Regulars flag RAK as having somewhat more variable weather than nearby Dubai and Sharjah, with the occasional strong wind day capable of closing beach access — a light sweater covers the evening chill.
