Narrative:

Normal flight to downwind psp runway 13R. As we descended to 5000 ft on downwind; the wind picked up dramatically out of the northwest 50 KTS variable 70 KTS; light turbulence on base leg 3000-2000 ft wind still out of northwest 50 KTS moderate turbulence; airspeed +/-10 KTS; surface winds approximately 160 degrees at 15 KTS gusting to 23 KTS. On final; 1500 ft wind out of northwest 40 KTS; severe turbulence; bank +/-25 degrees; flaps 3 degrees; gear down; +45 KTS airspeed; +/-500 FPM and probably more. Go around at around 1200 ft. +45 KTS airspeed; oversped flaps at setting 3 degrees; climbing rapidly with near idle power trying to manage the huge airspeed gain. Immediately asked for divert to ZZZ; declared minimum fuel. Landed ZZZ with 2.7K fuel uneventfully.

Title: AN A319 ENCOUNTERED SEVERE TURB AND WINDSHEAR ON APCH TO PSP. THE FLT CREW EXECUTED A GAR AND DIVERTED.

Narrative: NORMAL FLT TO DOWNWIND PSP RWY 13R. AS WE DSNDED TO 5000 FT ON DOWNWIND; THE WIND PICKED UP DRAMATICALLY OUT OF THE NW 50 KTS VARIABLE 70 KTS; LIGHT TURB ON BASE LEG 3000-2000 FT WIND STILL OUT OF NW 50 KTS MODERATE TURBULENCE; AIRSPD +/-10 KTS; SURFACE WINDS APPROX 160 DEGS AT 15 KTS GUSTING TO 23 KTS. ON FINAL; 1500 FT WIND OUT OF NW 40 KTS; SEVERE TURB; BANK +/-25 DEGS; FLAPS 3 DEGS; GEAR DOWN; +45 KTS AIRSPD; +/-500 FPM AND PROBABLY MORE. GAR AT AROUND 1200 FT. +45 KTS AIRSPD; OVERSPED FLAPS AT SETTING 3 DEGS; CLBING RAPIDLY WITH NEAR IDLE PWR TRYING TO MANAGE THE HUGE AIRSPD GAIN. IMMEDIATELY ASKED FOR DIVERT TO ZZZ; DECLARED MINIMUM FUEL. LANDED ZZZ WITH 2.7K FUEL UNEVENTFULLY.
