Southend, United Kingdom
SEN (Southend, United Kingdom) sits at 51.57°N, 0.70°E, 49 ft elevation — inland.
Major airport serving Southend, United Kingdom.
Computed from SEN's geography and climate
The jet stream meanders across this latitude seasonally — SEN sees its strongest CAT exposure in December–February, when the polar jet pushes equatorward and routes intersect it more often. June-onwards departures climb into cleaner upper-level flow.
Climbout is usually unremarkable — most turbulence on flights from Southend occurs at cruise rather than immediately after takeoff.
Winter (December–February) brings the strongest jet-stream activity — that's when long-haul departures most often log clear-air turbulence at cruise.
Get a real-time turbulence forecast for any scheduled flight out of Southend Airport, with live wind, jet-stream analysis and pilot reports.
Southend Airport is best described as a high-latitude airport. The jet stream meanders across this latitude seasonally — SEN sees its strongest CAT exposure in December–February, when the polar jet pushes equatorward and routes intersect it more often. June-onwards departures climb into cleaner upper-level flow.
Winter (December–February) brings the strongest jet-stream activity — that's when long-haul departures most often log clear-air turbulence at cruise. Peak turbulence window: November–February (strong jet). Typically calmest: May–September.
We combine live NOAA Aviation Weather Center data (PIREPs, SIGMETs, AIRMETs) with physics-based Ellrod and Richardson-number calculations derived from Open-Meteo pressure-level wind and temperature data. If a source is unavailable for a waypoint we show an em dash rather than invent a number.
