Annual Summary for 2018

 The year was statistically slightly wetter than usual, although Jan, Mar and Dec were very wet, while Jun and much of Jul were very dry.

Overall the mean temperature for the year was 0.9 degrees above average; from April through to July, and Nov to Dec, it was milder, while Feb to Mar were cooler than usual.

Jan/Feb/Mar were mostly wet and cool, while the combination of little rain and warmth made June/July challenging for growers at an important point in the growing season.  There were 222 frost-free days however, the 6th highest.

11 days with snow falling, totalling 29cm; most snowfall in a day 12.5 cm on 18/3/18.

The statistics hide the varied and sometimes violent weather of May 2018.  

Temperatures on average were 2.4 deg above normal, there were no air frosts recorded, and just one night on the 1st with a ground frost when the temperature fell to +0.1C.
Statistically a record warm month with mean temperature 14.3C beating 14.1C in 2017. The mean max temp was also a new record 20.6C, beating 19.6C in 1992.

Rainfall was slightly above average for May, but the distribution of it during the month was striking.  21 days (between 3rd and 24th) were virtually dry, but 10 days had appreciable rain (9 were classed as wet, 5 very wet). Indeed 15mm fell during 1st /2nd, while 44mm fell during 24th /25th /26th giving very heavy falls in a short time

The much reported thunderstorms began here late on the evening of 26th with rumbles, then vivid persistent lightning (much appearing to be cloud to cloud).
These continued throughout much of the 27th, with particularly violent thunderstorms here starting at 0215, then 0640 and also 1600.

Thankfully Halesowen was spared the late afternoon downpours suffered in the nearby Selly Oak and Edgbaston areas of Birmingham, we recorded around 5mm and they 59mm in an hour around 1730 .

There were many bright sunny days during the month (10 days with at least 11 hours good sunshine recorded), others with good sunshine for part of the day, contrasting with two really dull days on 25th and 30th (having no more than 0.5hrs sunshine recorded).

The only dull days were 4th, 17th and 19th, other days being mostly bright and sunny, and from 24th to 30th virtually cloud free.

Very pleasant month for being out and about, but hard work keeping all the allotment fruit and vegetables watered using watering cans!

Autumn has statistically been slightly milder and enjoyed slightly lower rainfall than normal so is not at all exceptional. However on the shorter timescale there was variation during the period, with drier and wetter spells, warm and cool times, one example being the colder week at the end of October brought an earlier than usual first airfrost.


December overall was milder than usual, although it was cooler 4th, 13th – 15th, 24th.
It was wet until 9th, then dry, then wet 15th to 25th, then dry again to finish the month.
