Narrative:

I was on the second trip of back-to-back identical schedules. I had a hard time sleeping on the first trip at the hotel since the room was very cold; but didn't deem it serious enough to write up in a report. On the second trip; we were advised that our departure time out of ZZZ would be over 2 hours later. The flight attendants going to my final destination were with me in ZZZ and I knew it would be impossible to leave ZZZ2 at the posted departure time. I did the math and concluded we would likely arrive in ZZZ2 well after XA00; and the forecasted WX included visibility of 1 mi in br; and temporary sn with lower visibility. I would also be changing to a new captain in ZZZ2. I was already feeling quite drained from the long unforeseen situation in ZZZ; and flying into potential WX at XA00 after being up for 19 hours did not seem prudent or professional. Therefore; I called in fatigued with the crew desk to give them as much time as possible to re-crew the flight. The crew desk requested that I deadhead and fly the return flight home the next day and I agreed.

Title: DELAYS; BAD WEATHER AT DESTINATION AND AN EXTENDED LONG DUTY DAY CAUSE B737-300 FO TO REFUSE LAST LEG DUE TO FATIGUE.

Narrative: I WAS ON THE SECOND TRIP OF BACK-TO-BACK IDENTICAL SCHEDULES. I HAD A HARD TIME SLEEPING ON THE FIRST TRIP AT THE HOTEL SINCE THE ROOM WAS VERY COLD; BUT DIDN'T DEEM IT SERIOUS ENOUGH TO WRITE UP IN A RPT. ON THE SECOND TRIP; WE WERE ADVISED THAT OUR DEP TIME OUT OF ZZZ WOULD BE OVER 2 HRS LATER. THE FLT ATTENDANTS GOING TO MY FINAL DEST WERE WITH ME IN ZZZ AND I KNEW IT WOULD BE IMPOSSIBLE TO LEAVE ZZZ2 AT THE POSTED DEP TIME. I DID THE MATH AND CONCLUDED WE WOULD LIKELY ARRIVE IN ZZZ2 WELL AFTER XA00; AND THE FORECASTED WX INCLUDED VISIBILITY OF 1 MI IN BR; AND TEMPORARY SN WITH LOWER VISIBILITY. I WOULD ALSO BE CHANGING TO A NEW CAPT IN ZZZ2. I WAS ALREADY FEELING QUITE DRAINED FROM THE LONG UNFORESEEN SIT IN ZZZ; AND FLYING INTO POTENTIAL WX AT XA00 AFTER BEING UP FOR 19 HRS DID NOT SEEM PRUDENT OR PROFESSIONAL. THEREFORE; I CALLED IN FATIGUED WITH THE CREW DESK TO GIVE THEM AS MUCH TIME AS POSSIBLE TO RE-CREW THE FLT. THE CREW DESK REQUESTED THAT I DEADHEAD AND FLY THE RETURN FLT HOME THE NEXT DAY AND I AGREED.
