We have had some rain during today, but this is still not exactly coming down in bucket loads as the amounts which are being recorded continue to be very small.

Over the course of the last day or so, a total of 3.0 mm of rain has fallen at Edinburgh Gogarbank which has been enough to more than double the total for there, for this entire month. However, a total of just 1.8 mm of rain has fallen at the botanic gardens in Edinburgh.

That takes the total for this month to just 4.8 mm at Edinburgh Gogarbank as at 11pm tonight, along with just 3.6 mm at the botanic gardens in Edinburgh during that time.

This means that there has now been just enough rain at Edinburgh Gogarbank to prevent this month from being as dry as this same month during last year, but it is now a different story at the botanic gardens in Edinburgh which are still struggling really badly, to get any significant rainfall.

This might not necessarily mean that this month will go down as the driest April on record at the botanic gardens in Edinburgh because that is a station which has been existence since 1956 and the only records which I have for there, only go back to 2009.

However, the current total for that particular station during this month is still short of the lowest April total according to those records which I have for there and as long as that remains the case, there is always the possibility that this month could be the driest April on record there.

The best chance of getting any significant rainfall has now gone and any further rainfall which occurs during this month is likely to be showery in nature. Since showers are always a hit and miss affair, there is always the possibility that we might get nothing at all from them in terms of any recorded rainfall, so the possibility that this month could end up being the driest April on record at the botanic gardens in Edinburgh still cannot be ruled out.

7 mm added to my total today.

8.8 mm this month.

---

Still 100% dry. Will be a zero rainfall month I think.

---

4.6mm on Mon & Tues so 10.1mm so far at Swanston (south Edinburgh)

---

5.6mm this month

---

This month's rainfall totals as at 7am this morning were 4.8 mm at Edinburgh Gogarbank and 4.2 mm at the botanic gardens in Edinburgh (for both of those stations, that is 10.4% of that respective station's 1981-2010 April average).

What is noticeable here is that this month won't now be going down as the driest April on record at either of those stations, after all.

Edinburgh Gogarbank is also not quite as dry as what it was during this same month during last year, but that is still not yet the case at the botanic gardens in Edinburgh where this month's total so far is now exactly the same as the total for this same month during last year.

The rains have failed !

As a result we now move onto 14 days absolute drought and just 6.8mm to show for what fell early in the month.

---

15.8 mm This  Month.

---

2.42 mm today

---

Equal driest April here since the creation of the earth. Well it must be as you can't beat zero rainfall

---

finished with 1.2mm this month!!

---

Still no more than enough to lay the dust on the coast, but the radar shows a marked convergence front 20 or 30 miles inland

---

18.2 mm final total for April.

---

Final tally for the month was 6.8mm

---

Total for April here was 4.6mm which is 9% of the Edenbridge LTA for the month.  This brings the total for the year to end of April to 207.3mm, which is 94% of the LTA for that period.

The lack of rainfall started in mid-March; in the 42 days (6 weeks) since March 19th it has rained on 4 days giving a total of 7.1mm.  Combined with a desiccating NE wind and humidities around 40-60% on many days (including one when it got down to 37%) this has meant that the ground here has gone from a quagmire to bone dry in that time (which is exactly the same as happened last year), and therefore why I have had to get the hosepipe out to water the garden regularly to produce the important Spring growth on my fruit bushes, apple tree, and vulnerable young cuttings.

---

Up until the morning of the 30th my April total was only up to 4.5mm, but then 12mm fell during the afternoon & evening to prevent this April being the driest one I've recorded.  Finished with 16.5mm, and April 2021 becomes only the 10th driest one I've recorded since 1983.

The latest rainfall data for Edinburgh Gogarbank (shown as station 1 below) and the botanic gardens in Edinburgh (shown below as station 2) is as follows:

24 Hour Rainfall Total Up To 09:00 UTC (10am BST) This morning: 0.0 mm at Station 1, 0.0 mm at Station 2

Final Total For April 2021: 5.2 mm (11.3 % of LTA) at station 1, 4.4 mm (10.9 % of LTA) at station 2

Number of Dry Days During April 2021: 24 at station 1, 23 at station 2

Yet another exceptionally dry April, but it wasn't quite our driest April on record at either of those stations, and April 2021 also wasn't quite as dry here as April 2020. Nevertheless, that was possibly our third driest April on record.

April 2021 was also a month which contained hardly any official rain days within it.

Total Amount During This Spring So Far: 53.2 mm (35.2 % of LTA) at station 1, 40.4 mm (28.6 % of LTA) at station 2
Number of Rain Days During This Spring So Far: 12 (36.4 % of LTA) at station 1, 13 (45.9 % of LTA) at station 2
Number of Dry Days During This Spring So Far: 38 at station 1, 37 at station 2

Number of Rain Days During This Year So Far: 40 (29.1 % of LTA) at station 1, 42 (33.8 % of LTA) at station 2
Number of Dry Days During This Year So Far: 57 at station 1, 54 at station 2

LTA = 1981-2010 average for the month, season or year in question.

All of this data has been taken from SEPA with each observation day starting and ending on 09:00 UTC on each day.
