The wife & I are hoping to start our long-distance walking adventures with Hadrian's Wall path this spring or summer (2018) ... she's from Newcastle area, but has been away for >30 years. We know it is ALWAYS going to rain, but what is the best time to likely encounter clearer weather? We hope to do a fortnight holiday from (from USA) across the last week of one month & the first week of the following (to better accommodate my work schedule) ... BTW, we live in Florida, so "warm" days will likely still seem relatively "chilly" to us!
