Off to Newquay for our holiday on Thursday, and it appears to be forecast to rain pretty much constantly. 
I really feel the cold, and it makes me miserable, so I need to make sure I take appropriate clothing and don't spoil everyone's fun by being a grumpy cow.
Anyone there atm able to tell me whether a rain coat and layers under it will be sufficient, or do I need to take my insulated winter parker?
TL:DR - is just wet in Cornwall right now, or wet and cold?
