The last three smokes on my 18.5 WSM I have had trouble reaching 225 degrees at the grate level. It would only get up yo 212. I opened all the vents wide open. Still only 212 for the entire cook of baby back ribs. As the cook was coming to an end the temps started to rise to over 300. I was able to complete the cook, just took a little longer and the ribs were fantastic. The last cook was on carport with rain and wind. Put a wind block around the WSM. The two previous cooks the temps were in 80s to90s with no rain or wind. I added more coal mid way through each cook. The first two cooks i used Kingsford blue that was fresh out of the bag although the bag was a couple of years old. Don't know if that has any bearing on it. The last cook was a newly purchased bag of K blue. Any Ideas?
