It's probably condensation, I had the same problem over the last hot weekend. I have thought that perhaps the woven groundsheets are not fully water proof, so next trip, I will also take a piece of poly sheet to lay between the footprint and sleeping pod ground sheet. If I have water on top, then I will know it's condensation.

Spent up, not pent up, just had my new tent up.

Most footprints and tent groundsheets aren't complete barriers to water coming in. Their Head Height rating tells you the amount of water pressure they can hold back but above that, water can penetrate, especially with the weave type material in common use. In this case you're standing on the source so are likely exceeding the rating and water is permeating - assuming no actual holes. I'd aim to stop the water coming through by nipping out for a cheap plastic sheet from somewhere and get it between the tent and the footprint, ensuring as best you can that no water can get in to lie twixt sheet and tent. Other option if possible is to move to a drier area on site. Good luck.

raf's idea is sound. Hadn't thought of condensation.

If it's near the walls its probably condensation running down and you haven't noticed.

I'd go for condensation too as the explanation.

Love our set-up and need no more tents or gear, so trying to stop looking!

Another vote for condensation, personally I think that water penetrating from the groundsheet is highly unlikely unless there is damage somewhere. we have quite literally ended up in a pond after heavy torrential rain with absolutely no water ingress through an outwell sig and that was without a footprint. I am not sure that adding an extra layer of plastic under the tent would do anything other than cost you more money.

Hi, also make sure that any groundsheet you have isnt visible around the edges of the tent. Any rainwater needs to run off your tent onto the grass and soak away. If water can run off your tent onto a groundsheet it will then run under the tent and could seep through.
I also echo what others say though, if a modern tent appears to be leaking it is condensation 95% of the time so make sure you have some vents open.

Do you think you could have a leak in your tent/door? It could then run under the carpet to the lowest point.

I have never been a great believer in using footprints. Keeping the underside of a tent groundsheet spotless isn't a priority with me. If water does get between the footprint and the tent groundsheet you will basically be sitting in a pond and I am not sure how waterproof a groundsheet would be if permanently sitting in water and being walked on. Without a footprint the underside of a tent's groundsheet will not get too wet unless you are unfortunate enough to suffer torrential rain and flooding. Cold water laying between the footprint and the groundsheet may also be responsible for condensation within.

I vote for some kind of condensation too.
On my last trip I experienced water puddles on the SIG of my tent, it hadn't been raining and the grass was dry.
Then I saw that the water was close to the walls, and at places, were shelfes or boxes had touched the fly sheet from the inside. The condensation at night on the OUTSIDE of the tent that way could seep through the fly and ended on the floor, although we hadn't recognized any condensation on the INSIDE of the fly sheet!

Funnily enough we had water between sig and footprint while in Inverness. It had rained steadily during the day and heavily overnight. On leaving the next day, during a dry spell in the weather, we found quite a puddle on the footprint in a depression in the pitch - if you follow me.
The pitch sloped very gently and we use an airbed that would have been above the puddle. Luckily, we had no real ingress of water through the groundsheet and the tent was dry inside - so definitely not condensation. I suspect because of the slight slope and the heavy rain that water had run in between the tent and the footprint.
I am not sure how to avoid this apart from paying careful attention to pitching and run off. We completely dried out the tent at the next site - near St Andrews - so were quite lucky
