Advice on gloves

I bodyboard in Cornwall in the summer but now have arthritis in the fingers of both hands.Would the gloves normally used in winter with wetsuits help keep my fingers warm & supple? I have never used a wetsuit as I only bodyboard in summer.I don't want to wear a suit as don't need it in summer so I realise I will look strange with just the gloves on but if they work & keep me surfing who cares!!!!!!!What sort of glove would be best? I'm female not that will make any difference to the type of glove!!!!!!!! Thanks for any advice .
