The normal (1971-2000) rainfall for this period is 634.1mm. So far (with little sight of appreciable rainfall in the near future) the total is 301.5mm or just 47.5% of the Nov-March norm. Nov 1991-March 1992 produced a total of 316mm at the old Penzance site ... you'll do well to beat that :-) Philip Eden |

But the old site is just behind the sea front & just above sea level, and I'm a good 800metres inland and at 60m alt. My rainfall figures are extremely similar to the EA site at Drift Dam (same altitude as me, 2 miles to the west). My records start 1992. Taking Drift for Nov-Dec 1991 (136mm) + My rainfall for Jan-March 1992 (185mm) gives 321mm Not much difference, but I might just beat it. The difference beween my site & the old Penzance site during the 90's was greater in Summer, as the old Penzance site was less prone to catching the sea breeze convergence showers. Graham |
