Dull December 2018

The brightness of this morning soon disappeared as the cloud filled in the blue gaps of sunshine.

This December will go down as my dullest ever with just 51.6 hours of sunshine to date. My December average over the last 12 years has been 82 hours.

The persistent dry weather since the 24th isn’t going to stop this month from being rather wet

At least it’s been mild……

A rather cloudy November

Makes a change to see some sunshine today though yesterday was a lovely day too.

Sunshine has been a bit on the low side this month. Only up to 66 hours (1st – 26th) and this November will probably end up one of the duller of any months I’ve recorded since 2006. And to think, the last two Novembers had 126 & 128 hours.

Mean monthly temperature at 9.8C, so nearly a degree above normal. Rainfall coming up to 100 mm and with more forecast, this month is going to be a really wet one.

Super Severe October Frost

I recorded the lowest October temperature since before 2005 and completely trounced my previous lowest October minimum of -2.2C (21st October 2010).

Last night’s minimum was -4.3C. I frequently have recorded entire years where the temperature never gets that low.

It was exceptional, especially given that October frosts are fairly rare (the last one being in 2010). But a beautiful day ensued with unbroken sunshine yet again and a maximum of 11.2C.

Going off chilly again! Could be another humdinger.

October Air Frost

A fairly rare October air frost here today with -0.1C. Did a bit of scraping of ice off the windscreen this morning. Something I normally don’t do until well into November or even December.

A maximum of 11.7C here today with cloudless skies and unbroken sunshine all day. Sunshine total now at 150 hours, so definitely into the sunny category.

Going off chilly with another frost possible though if that land breeze sparks up again, it might just stave off another air frost.

Monthly mean temperature anomaly now just +0.1C, though the mean maximum temperature is still above normal at 16.7C.

October 2018 – 1st to the 18th, Warmer than normal

A little over halfway through this month and so far it has been warmer than normal by both day and night.

Rainfall above average and sunshine somewhat below.

1st – 18th
Mean minimum = 9.8C
Mean maximum = 17.5C
Mean = 13.7C
Rain = 49 mm
Sunshine = 67 hours.
Days of no sunshine = 3.

A rare, early October grass frost recorded on the 7th (-1.1C). Only 4.1 hours of sunshine recorded from the 12th – 17th!!

A windy day thanks to Storm Callum

Not quite as windy here in this reasonably sheltered river valley spot as other areas of the South West but we are exposed somewhat to the south (the coast) and the wind was frequently gusting over 40 mph with one gust reaching 52 mph. This is the highest wind speed I have recorded this year.

Rain has mainly been in the form of drizzle but there have been the odd heavier bursts. Today’s rain now up to 15.6 mm. Monthly total at 25.2 mm.

Wind has eased off a little recently but still hovering around 25 to 35 mph. A few trees and large branches down here and there. Exmouth seafront was impassable in places due to flooding from the waves crashing over the wall. Any cars left alongside the Esplanade in Sidmouth will have been totally pebble-dashed by now. Dangerous to walk along there without a hard hat on.

Warm October Nights Ahead

Another pleasantly warm October day with a maximum of 21.7C and pretty much unbroken sunshine all day.

Looking at the forecast, there could be some unusually warm nights over the next few days.

My highest October minimum was 16.9C on the 3rd in 2013. Overnight Friday and into Saturday morning looks like a contender. Maybe a minimum of 17C to 18C?

Temperature holding up this evening at 17C but no record on the cards methinks as the sky is clear.

October Warmth

A mostly sunny and warm day with a maximum of 22.5C.

This makes it the warmest October day since 2011 with 25.6C on the 3rd.

Dew points were around 17C for most of the afternoon making the gentle sea breeze feel soft and warm. With the first hints of autumnal colour starting to appear and the deep blue sky, it made for a beautiful, colour contrasting day.

Sea breezes in October are not common and we’ve had quite a few lately.

A mild, calm evening – feeling more like summer than autumn.
