The 2019 Swale Match, Saturday 10th August

Having taken careful note of the developing depression due over the UK at the weekend, along with associated winds of 40 mph, the Committee have regretfully taken the decision to cancel this year's Swale Match; it's a disappointing decision to have to take but the only sensible option.

Next year's Match will be on the 15th August, not the 8th as advertised in some places. We'll hope for some gentler summer weather.
