Weather in the BH is about as unpredictable as anywhere. I was out there last year around May 23rd thinking the chances of blizzards were less....that was incorrect. It snowed, rained, sleeted and never got about 40 degrees in the three days I was there. I could go those same days this year and it can be 85 and you get sunburn. You literally need to bring all the hunting gear you own to prepare for absolutely any type of weather.
