How turbulent is DXB-DEL typically?

Smooth outside monsoon season; short convective bumps between June and September.

What is the best altitude to avoid turbulence on DXB-DEL?

Cruise at FL350 or above and deviate around cells. Monsoon storm tops are high, so lateral avoidance does most of the work.

When is the best time of year to fly DXB-DEL?

October to May, outside the monsoon. Flights between June and September see the most convective activity.

What causes the turbulence on this route?

Monsoon thunderstorms and the strong vertical air movement inside and around them.

Dubai to Delhi: what the DXB to DEL corridor looks like

Departure: Dubai International Airport, Dubai, the United Arab Emirates
Arrival: Indira Gandhi International Airport, Delhi, India
Great-circle distance: 2,183 km (1,179 nm)
Typical airborne time: 3h 02m
Usual cruise levels: FL330 to FL390
Initial track: eastbound

Route overview

The DXB to DEL sector connects Dubai International Airport in Dubai, the United Arab Emirates, with Indira Gandhi International Airport in Delhi, India. Measured along the great circle the two airports are 2,183 km apart, roughly 1,179 nautical miles, which is close to 3h 02m in the air before winds and routing are taken into account. The initial track is eastbound, and the middle of the route sits in subtropical latitudes.

Leaving Dubai

Dubai sits between desert and the Gulf, and departures climb across the coast within a few minutes. Summer surface temperatures create a deep, well mixed layer, so the climb out through it can feel busy even on a clear day. The great-circle track leaves DXB eastbound, and the first waypoint band of the flight sits close to 26.1N 60.8E. On a sector of 3h 02m, the climb to cruise takes roughly the first twenty to twenty five minutes.

Monsoon season convection

The midpoint of the DXB to DEL track lies near 26.9N 66.2E, about 1,092 km from Dubai, which is where the corridor spends its longest continuous stretch at cruise level. This corridor is shaped by the monsoon cycle. In the wet months convective cells cluster along the coastal section of the track, and the crew works around them with radar. In the dry months the cruise is generally smooth, with light movement limited to climb and descent.

Cruise altitudes on this sector

Medium haul sectors typically level off between FL330 and FL390, with a single step climb once fuel burn has lightened the aircraft. Choice of level matters because turbulence is layered: a change of two or three thousand feet often puts the aircraft into calmer air, and that is one of the first adjustments a crew will request.

Arriving into Delhi

Arrivals into Delhi descend across flat plain terrain. In the pre monsoon months dust laden thermals reach several thousand feet, which is the usual explanation for the bumps on the last part of the descent. Descent normally begins around 27.7N 71.7E, roughly 546 km before DEL, and takes about half an hour from cruise level to touchdown.

Seasonal pattern

June to September is the monsoon window and the most convective part of the year on this corridor. October to May is normally quiet at cruise level.

Flying this route with less worry

It is worth remembering that turbulence of the kind found on the DXB to DEL track is uncomfortable and entirely within what the aircraft is built for. Wings are designed to flex, the flight is planned around the forecast, and the crew adjusts level or track when it helps. The live forecast above shows the current picture for this corridor so there are fewer surprises on the day.
