Anyone have issues with their grill coming up to temp slower when it is really humid for a period of days?

I thought I did a few weeks ago on my Memphis and I had just put a new igniter rod in the unit a few months earlier.  I was wondering if the humidity may somehow impact the pellets in the hopper and add moisture content to them causing them to burn slower.

I live just North of the Gulf coast of Alabama and I have not had any issues with the humidity.  My smoker sits outside with a cover on it and that is all.  I keep pellets in the hopper all the time.  If anything I have issues with the salt from the coast.

 Not on my Memphis Pro. Starts and heats quickly. Perhaps faster in the high heat. Has been very hot with average humidity . Last few days, extremely high humidity with heat into the 90º range. Humidity now

 93% @ 10:34 Am.

Here is what happens when a small amount of water gets into your dry pellets. Followed by a discussion of the effects of humidity. Also a review of how waterproof heating pellets are made.
Bottom line, I am satisfied that humidity does affect how pellets perform. And remember--the bags they come in are perforated--so store them in a dry (preferably low humidity) place.

Have not noticed it over the last 3 weeks and the backyard is like a swamp!

I could have been my impatience too

Mine stay in a covered and sealed area, I have never noticed any difference and our humidity is unrelenting in the summer.
