Are we set for record July rainfall?

While July has seen a good deal of dry and bright weather, we’ve also seen a few periods of heavy rainfall.

Whether through intense thundery downpours or prolonged periods of rain such as seen in southern parts of the UK on Friday last week, these events have dramatically pushed up the rainfall totals for the month.

This has led to speculation about whether this July could be on course to be the wettest on record. However, a quick look at the statistics shows that while it has certainly been wet, we’re unlikely to break any national records this month.

Provisional rainfall statistics for July 2015 so far suggest that with 5 days of the month remaining much of the country has already received close to or above average rainfall for the month – but we’re some way off breaking the records for each country.

Table showing rainfall figures so far this month compared to average and the records:

Rainfall 1-26 Jul 2015 Current record July 1981 – 2010 average
UK 93 mm 146 mm (2009) 78 mm
England 70 mm 129 mm (2009) 63 mm
Scotland 128 mm 186 mm (1940) 100 mm
Wales 102 mm 241 mm (1939) 93 mm
Northern Ireland 95 mm 186 mm (1936) 81 mm

The wettest regions compared to average have so far this month been eastern Scotland, East Anglia and the south west of England. If records are going to be broken they will most likely be localised rather than national records.

Even those regional records are far from a sure thing. The weather is generally improving for most parts of the country and high pressure, bringing more settled conditions, is expected to build towards the back end of the week.

This means the last few days of this month are unlikely to add big rainfall numbers to the totals we have so far.

  1. I went outside with a jumper on today and I came back ten minutes later, turned on the central heating and made myself a warm hot drink to warm up

    … and you are japping on about rain?

  2. The storms on 4th July/17th July gave 9mm and 4mm respectively here (Mid Norfolk). July total is currently 87mm, with 64mm of that falling in the last 3 days. No prizes for guessing the current wettest month of 2015!

    Oh for goodness sake what a ridiculous article speculating about whether we are likely to set July record rainfall records written four days before the month ends. Why not wait until the month finishes?

    I suspect it’s more of the same propaganda as usual to get the words “record rainfall” out in the public domain to fool the public, even if it turns out there was no record at all come the end of the month.

    No mention of the cold weather though.

  4. It appears that they are, hence the name of the post
