Caravan in the Isle of Wight in September - will it be cold?

[RaspberryBlower]

I'm thinking about a static caravan in the IOW at the beginning of September but I'm worried dd will be cold at night. She'll be 18 months. We're flying/ferry so can't really take a heater or anything.

Anyone any experience of this?

The Isle of Wight has the same climate as the rest of the British Isles...so ifs it going to be cold/warm/everywhere it will the same there. Pack more layers if you have to!

Thanks for reply.

The caravan park woman tells me she'll put a heater in dd's room so will be OK.

She's probably as I've done nothing but bother her all day with my requirements for pfb's safety and comfort.
