Narrative:

On stable approach into seattle severe windshear was encountered and a windshear warning was observed at 400 ft. An immediate max thrust go around recovery maneuver was executed. Initial assigned altitude of 3000 ft was reached and since the conditions persisted we climbed through 3000 ft and while in contact with ATC 6000 ft was assigned as new altitude. Upon reaching 6000 ft we encountered strong turbulence and continued climbing while talking to ATC that assigned 8000 ft altitude. We leveled at 8000 ft; reconfigured the aircraft and contacted dispatch of conditions. Since several other aircraft reported similar events/observations and weather reports indicated no significant change of the severe weather we diverted to portland (in contact/agreement with dispatch) and landed. After refueling and a wait for better weather in seattle we departed portland and landed in seattle without any further issues.I would like to practice flying in such severe/critical conditions in the simulator. The high workload in a situation like this should be trained in different realistic scenarios to prepare crews as much as possible for such an event. CRM during the event worked really well and we neither lost control over the aircraft nor situational awareness at any point. Nevertheless I suggest more training for such conditions. Thank you.
