Rainfall Records Keep Coming!

What is it about Fridays and record amounts of rainfall. A couple of weeks ago Friday 22nd June set a new daily rain record of 35.1mm. Now two weeks later Friday 6th July replaces that record with 39.2mm (1.54”) which fell in the 12 hours between seven o'clock in the morning and seven o’clock in the evening. That’s equivalent to our average total July rainfall in 12 hours. Needless to say it’s resulted in lots of local flooding.

Worryingly next Friday will be Friday 13th so there’s no telling what might be in store for then.

The weather has certainly produced lots of rainfall over the last 3 months. Back at the end of March we had only received 60% of the rainfall expected for the previous 12 months. There were many dire warnings about what would happen if we had another dry summer and winter and how many years it would take to recover. A drought was declared and since then the rain’s arrived in abundance.

We’re now back up to having 100% of the amount we can expect over a 12 month period thanks to record levels of rainfall in June and July. So far this year I’ve recorded 439mm (17.3”) already slightly more than for the whole of 2011 when the rainfall amounted to 431mm and we’re only half way through the year.
It would now be nice if summer would start and we had some warm, sunny and dry days. Unfortunately the forecasters don’t seem to be suggesting that might happen anytime soon.

At least the forecast is for a dry day on Saturday.


  1. Yup, you've done a great statistical job of summarising, Martyn. Thanks. Last night was deluge upon deluge here in Edinburgh, so the Met map of forecast rainfall was accurate. Too late to convert your summer house to an ark?

  2. That particular requirement wasn't in Sue's design brief.
