Remarks
-------
Unsurprisingly, it was, by a considerable margin, the hottest, driest
and sunniest summer in my 10-year record here. The significant rainfall
deficit remains a relatively short-term phenomenon. As at 31st August
2018 the running rainfall totals and percentages of average we

90-day total: 94.5 mm (32%)
120-day total: 115.8 mm (29%)
180-day total: 387.5 mm (65%)
365-day total: 1098.6 mm (91%)

These percentages do not take seasonal variation into account.
