HISTORICAL EVIDENCE FOR THE 19-YR CYCLES
From the Annals of Loch Ce, we know that the summer
of 1252 and 1253 was so dry that people crossed the
river Shannon to Ireland without getting their feet wet. This
matches the conditions of 1975-76, which have been the
worst drought in England and Wales since rainfall records
began.. The difference is 722 years, almost exactly thirtyeight
19 year cycles.
In between (nearly sixteen 19 year cycles later) was
the Great Fire of London in 1666, which was a period so
dry that the River Thames was just a trickle.
In NZ a severe drought occurred in Otago, in the South
Island in 1982. It was repeated in 1999, almost one cycle
later. Each time it was described as the worst in living
memory. Rather than any momentous shift in the world’s
climate, it is far more likely to be an indication of the fallibility
of the living memory.
There is no doubt that looking back to old records
works. Some alternative forecasters latch onto just one
system that works for them – they adjust it in their mind
slowly over time with careful observation once they get a
basic framework. One often encounters farmers, surveyors,
mountaineers, fishermen and foresters who are legendary
forecasters in their own environments. They swear by
what they have come to know and rely on.
4. CHECK OUT THE WIND
According to ‘Buys Ballot’s Law’, dating back to
1857, when the wind is blowing on your back, the low
pressure(bad weather coming) is always on your left hand
