Sleeping bag 1 or 2 season

[Ania]

Going to start my walk from SJPP next Thursday. Do you know what the weather is going to be like in September on camino as dont know if to take 1 or 2 season sleeping bag?

Only you know how warm you like to be when sleeping. Some nights will be too hot to sleep. Other days will have cool mornings and evenings. The higher elevations can be cool at night any time of year. There will be other pilgrims in the room keeping it warm and humid. Inside always will be warmer than outside in September-October.

A sleeping bag with a rating of about 50F should be sufficient under all circumstances. Look at a weather site almanac to see what September was last year. It will be the same this year, but on different days.

You will likely be sleeping indoors. Some albergues will be too hot and others too cold. If its too hot just use the liner. If its too cold borrow a blanket. Your sleeping bag rating is of no matter ... the critical factor is that you bring the lightest you can bring.

I'm pretty sure you won't need a heavy weight bag. I took a Quecha sleeping bag with a "S 15 degrees, light" rating. I slept with long underwear bottoms and a light t-shirt. and I was comfortable for the entire mid May - end of June Camino this year. I slept in albergues almost the entire time. The albergues were comfortable, temperature wise, for me. If I was hot, I kicked the bag off and was still comfortable. If I was cold, the albergues all had blankets. The bag was light and easy to pack. I used a jumbo zip loc baggie rather than the stuff sack that came with the bag for ease of packing and waterproofing.
Hope that helps. Have fun!

Thank you so much everyone for reply and help. I made up my mind after your replies and will take smaller, lighter sleeping bag season 1 and as you said I can always cover myself with blanket if too cold. Now cant wait as this time next week I will be waking

Remember that you emit about a pound of water a night through perspiration, so your sleeping bag needs to air to permit evaporation. It can even get moldy if kept in plastic too long. The baggie is fine after your sleeping bag dries.

Do you have a source? I couldn't find one that supported this claim, but did find one that gave a layman's explanation here. In summary, insensible perspiration is around 25ml/hour, and most of that is exhaled during respiration, so it won't be absorbed by the sleeping bag, and one would need to be sleeping for 18 hours for that to reach 450ml (~1 lb). For active sweating, the room would need to be about 30degC/85degC, but if one is in a bag, that temperature might be reached inside the bag even if the room is not that hot. I think it would be so uncomfortable to sleep at that temperature that one would have discarded the bag anyhow, and not continue sleeping in it.
My approach is always to use a liner, and I have never found it to be obviously damp in the morning, so I suspect that it it might only be retaining a very small amount of moisture if any at all. Provided the bag isn't stored long term in a zip-lock bag, I don't see that using one on the Camino would be a real problem.

Awesome information - I had no idea this would be something to consider. Thanks Falcon!

I am thinking of going for this one, or perhaps

(600g, and pack size 26cm X 13cm)

Not sure I will bother with taking a liner anymore if I go for either of these.
