My advice..
1.. Set some personal operational limits for yourself and stick to them. Consider them your Standard Operating Procedures and don't deviate from them unless you are prepared to fly in those conditions. If you pick 15 MPH as the limit, you know that if the winds including gusts are that and below you are good to go with no special planning. Outside of that you can do but I would operate with extreme caution and plan for how you are going to operate within these conditions.
2.. Know the wind speed (including Gusts) and direction before you launch. The P3 does not take into account wind direction and speed when calculating the low battery RTH, so if you sent it away downwind you may be in for a surprise when trying to return. One thing you could do here is raise the low battery RTH threshold for these specific flights.
3.. Remember, wind speed and direction can change as you gain altitude. Most forecasts are general forecasts and are expected wind speed and direction. I actually have a Weather Station at my place that tells me this live and it reports to Weather Underground. (
Weather Forecast & Reports - Long Range & Local | Wunderground | Weather Underground) There are people like me all over the place that do the same, so you might find someone reporting wind and direction close to the area you are flying in. You would be surprised how often there is a difference between the forecast and actual reported on ground in the area as there are so many mechanical factors that can be in play. The forecast will most likely be close to correct at 400' but the surface direction can be vastly different. If you know both of them, you can make some good informed decisions.
4.. As others have mentioned, practice....Go find an area that is very open and fly in windy conditions. It will go along way towards understanding your level of comfort and limits in different conditions.
Personally, I don't fly in anything beyond 25 KPH winds. It is not worth the risk for me and like others have mentioned, I do this for the video footage, which suffers in very windy or gusty conditions.
Coming from aviation perspective, bad things happen when people are unprepared for their conditions. If you know your limits and can recognize when you are going to reach them and have a plan, you will have happy flying.
