Weather
We departed...on time and headed to [destination]. The current METAR reported winds 190/14 Gusting 26Kts; 9SM; OVC 800 ft. The TAF for our time of arrival reported winds 190/10 Gusting 18kts; 3SM; -RA; BR; BKN 600ft BKN 3500 ft. Upon descending; Approach gave us a PIREP from a King Air that had landed an hour prior. He had reported wind shear with a +/- 25kts. After adding the wind shear escape maneuver to our brief and changing our configuration to land with Flaps 22; we continued with our approach. Around 1;000ft; we started to fly through some turbulence and gusts of wind. By 500 ft; the gust had intensified and it felt like going through wind shear but the plane did not give a warning. Around 400ft; we executed a normal go-around and with max thrust and flaps 9. We got very little climb and set off the GPWS momentarily. We climbed to 2000 ft and reviewed the flight plan to make sure we had enough fuel to come back for a second approach; which we did. After being cleared for the second approach and on final; Tower gave us an update on the weather and it had deteriorated; putting the ceiling at 200ft (below our minimums). We canceled the approach and told them that our intentions was to divert to our alternate. We immediately advised Dispatch of our intentions; and told them that we had 4500 lbs. All we received was from them was an OK and the Weather at [alternate]. Approach made us fly east bound for a few minutes; while they were getting our clearance. We asked them for a vector towards [alternate]. We monitored the fuel and noticed that we had a 70kts headwind; and with the long arrival; we were going to burn more than the expected fuel. We declared Min Fuel; and asked for a more direct route. We ended up landing with 2500lbs of fuel. We could have skipped the second approach and decided to go back to divert with more fuel; especially after going around for wind shear. Dispatch could have been a bit more involved; especially after we reported to them our intentions; with the amount of fuel we had on board; and the headwind we were experiencing.
EMB-145 First Officer reported encountering windshear on final then a GPWS alert on the go-around due to a slow climb rate.
