Human Factors
While on the RNAVM XX in ZZZ1 we encountered a GPWS event. At the beginning of the approach we had a tailwind and the descent angle of the approach caused us to be a little fast starting the approach. As the pilot monitoring I should have caught this issue sooner and brought it to the attention of the PF (Pilot Flying). Because of the speed the PF disconnected the autopilot/auto throttles and slowed the plane to the proper approach speed. During the turn onto final the PF was visual with the runway and let the nose drop which caused a momentary don't sink. He corrected and the warning went away. Still with the airport visual he tried to correct on the VASI and received another momentary don't sink call at around 700 ft. We continued the approach and the landing was normal. I don't have anything to add for [this report].I have learned many lessons from this very short flight. I haven't had much ZZZ experience and my FO (First Officer) who was PF has had very little. We tried to mitigate the possible issues by having a slow cruise speed of 210 kts. and trying to get ready for the approach early. We briefed the 3.4 GP and felt we were in a good position for the approach. With the unfamiliarity of the situation and the weather in ZZZ this day I missed the strong tailwind that was making our situation worse. This put us behind and we had to play catch up. It was turbulent the whole flight and when he disconnected the AP/AT my [situational awareness] went down because I was worried about his flight path at that time. As I look back at the event and if I could do this again I would have us discontinue the approach early and come around to try again. Once we continued and got out of the [weather] and had the runway visually climbing back into it in that terrain did not seem the safest option. But if we had bailed early it would have made the situation easier the second time.
B737 Captain reported an uneventful landing after two GPWS alerts during approach due primary weather conditions.
