Some of you may have already seen this but found this video on how weather, especially wind affects the archer and shooting.
Being a traditional archer using wooden arrows and feather fletching, I can concur that wet weather has a huge effect on feather fletching and wind does throw them off too.
Some good advice in the video is to manage your expectations. If the weather is bad you aren’t likely to break any records. Also when going to a shoot check the weather forecast, so you know if you need wet weather clothing, or sun block if sunny (not a problem that many British archers have suffered from this year)
