It does make me chuckle a bit to read the perception that all the locals in Cornwall are unfriendly. What a generalisation! I moved here over 20 years ago and it is no different to anywhere else - some people are friendly and some are not. On the whole I have found it to be the most welcoming place that I have ever lived in.
A 10 minute walk through town, normally takes at least double the time as there is always someone to say hello to. I can't understand why anyone would think that Cornwall is 'socially empty' in the winter. It is true that a lot of locals do keep a low profile in the summer days when it can get very busy, but we are still very much here!
Whether living here would suit you or not very much depends on the sort of person you are and what is important to you. If you do not drive and have to rely on public transport then you might find that problematic. It is not always that easy to get a taxi unless you have planned in advance. If you need to access hospital services frequently, then we only have one main hospital in the county.
I have felt so fortunate to live where I do throughout the lockdowns. I can walk to woodland or to the coast. It has been such a blessing. It does rain a fair bit at times, and sometimes in the Summer, but the Spring and Autumn are normally amazing. It is also a bit warmer down here and at times can feel like a tropical paradise when we do get the sunniest days.
We have many fabulous restaurants to visit with extremely talented chefs and I hope they will all manage to survive the enforced closures during the last year. So much beautiful coast line to explore and I am still discovering new places 20 years on. It did take me about a year to settle, but ever since then I have never looked back. I would never live anywhere else.
There are many others who have had the same thoughts and houses are being snapped up around us - some are being purchased without being viewed by the buyers! There is a chronic shortage of rental properties and when something new comes available it is snapped up instantly.
We are preparing ourselves for possibly the busiest summer ever this year, and from what I have heard many places are fully booked beyond the summer into autumn and winter. This is a great thing for Cornwall (although I am sure there will be a few times when I sigh a bit because I am stuck in traffic!)
If you are thinking about moving to Cornwall then do lots of research into the areas as they can vary considerably. It is fair to say that jobs can be hard to find depending on what your area of experience is.
