Pitch black, raining cats and dogs, lightening all around me, and waiting for my ride home. Not fun.

36' center console with triple 300 yamahas on the GOM running long (~110 miles) in seas that built the farther we went.  Destination was a spar rig for tuna at night.  Had a 150 gallon bladder on the back deck so no place to put a bean bag chair in the back of the boat until it was transferred.  In front of the console it was brutal.  Every time the boat fell off the back of a wave it pounded me.  Each breath had to be intentional between the pounding and the spray.  This went on for hours.  The shock snapped every rocket launcher off the t top.  The crew discussed the conditions and chose to continue to the rig.  The wind layed at dark, we caught fish all night, and returned home in easy following seas when the sun came up.  Took about four days to recover

One time 30 years ago we went too Slims, on the south side of Lake Okeechobee. We went through Boy Scout cut out to the outer edge of the big lake. We had a great couple of hours fishing and then noticed clouds building to the north and the west. After a half an hour the clouds gathered to the south. We were getting circled by this storm. We started running for the safety of the rim canal, and the skies opened up and the wind began to blow. As we got closer to Boy Scout Cut we noticed wind had been blowing water toward the cut and the waves were almost 3 or 4 feet in size. Being so shallow the wave build quickly and it can get ugly. We were so glad to get back to Slims and the safety of the truck. An hour later it was beautiful again.

I learned a valuable lesson that day. Okeechobee can get real dangerous quick when a storm approaches. Don't wait to long to head for the dock, and those cuts become dangerous when all that water builds behind them.

Santa Ana Winds.  They typically happen here in the colder months, late fall to early winter.

 

It isn't just the velocity, but the bursts & direction changes.  You will go from a steady 10 mph northern wind to a 35 mph gust from the east back to 10 mph from the NE followed by a 30 mph gust from the north.  Throw in a few dust devils swirling around like mini tornados.  The velocity make boat control & casting accuracy near impossible while the direction changes eliminate calmer spots.

 

Only positive is they raise the air temps, so the days following them often find the fish more active.

 

This times a thousand! I live right down the road and the Santa Ana's aint' nothing nice! Fishing is bad and catching is often worse!

Arriving at Lk St. Clair only to met with 25+ winds with gusts up to 45, scattered rain and temp drop. Sure was a wet and bumpy ride. Crazy

At Table Rock last April we had it go from dead calm to 30mph winds, rain, hail, and lightening, all in about 20 minutes time. Had some of the heaviest rains I've ever seen start falling 30 minutes after we got to the lake on day this fall, really bad lightening too. I've fished an 8 hour tournament through 20mph winds, rain, sleet, and snow. 

getting caught in 7-10 footers (not an exaggeration it was what the NOAA report said they were) on erie. Coast guard was keeping an eye on us when we were heading in just in case. They said they'd see us on top of a wave, then we would disappear for about 3 seconds, then see us again. We made it because my dad is extremely experienced on erie but I required a change of underwear and pants...

 

When we were at the bottom of the wave (between two of them) the water towered over us, one of the scariest events of my life.

Pucker factor right up there when we had to take waves at an angle on the upper Columbia River as when you hit them straight on you felt like you were going to flip backwards.

Today was the worst for me. All ponds and lakes by me are frozen.

Trying to catch a bass at night in the middle of Dec.  I didn't get one but my buddy did.  Other then that, cold, windy rainy days.....Only thing worse then being cold is being wet and cold.

I'm assuming that you’re asking about the 'worst fishing conditions' and not the most hazardous fishing conditions.

 

Among the worst fishing conditions that come to mind is cold muddy water,  particularly when the air temperature

is lower than the water temperature. In this situation you’re dealing with a double-whammy:

you're dealing with bass burdened by a narrow sight window coupled by bass with slow reaction times. Furthermore,

when air temps are lower than water temps, there's little hope for an uptrend in temperature or bass disposition.
