Today's provisional maximum temperatures across the Island; Maison St. Louis 37.9°C (1.9°C above the previous record). Jersey Airport 37.8°C. Howard Davis Farm 36.3°C. A potentially record breaking warm night ahead, with a forecast minimum of 23°C.
With a maximum temperature of 35.7°C recorded so far this afternoon, it is the hottest July day on record and 2nd hottest day since official records began in 1894 at the Maison St. Louis Observatory, Jersey.
The temperature at the Maison St. Louis Observatory and Jersey Airport have now surpassed the all time record of 36.0°C and will continue to rise until late afternoon. Records began at St. Louis in 1894 and at the Airport in 1951.
After the record breaking heat yesterday, it’s been an exceptionally warm night at Maison St. Louis Observatory, with the temperature not dropping below 27°C so far. To put this into context, that’s 5°C above the average max daytime temperature we would expect in mid-July.
Jersey has recorded its highest March air temperature since records began at Maison St Louis in 1894, with the value so far today reaching 21.4°C at 240pm. The origins of this very warm air can be seen shifting up from central Spain across Brittany.
With clear skies tonight, there's no better time to go looking for comets

It's best to look north between midnight and dawn. Just to show how visible it is this picture was taken with a mobile phone. Thanks to Thom Flaxman for the photo.
Strong updrafts around the island led to a very well defined funnel cloud appearing over St Aubin's Bay for around 20 mins at lunchtime today. What a treat!!
Jersey smashes March temperature record !!
The Maison St Louis observatory recorded its highest March air temperature since records began in 1894, with the value soaring to 22.9°C late this afternoon.
This time yesterday a severe thunderstorm affected the island bringing frequent lightning, strong winds, torrential rain and some flash flooding. The lightning map below shows all lightning strikes between 7pm and 10pm. Thanks to Matt Noel

Please stay safe and away from the coast for your safety.

án will develop and transfer eastwards through the day
Here's the latest 👇
Good evening, the snow has now almost reached as far as the north coast of Brittany and is still on track to be with us in the Islands after midnight. We'll be here monitoring the situation as always, and although it'll be a busy night shift we'll update when we can.
For the second day in a row, we have broken our Island maximum temperature record for the month of February.
Yesterday, we recorded 16.9°C on the official thermometer at the Maison St Louis observatory.
Today, we went on to to record 17.1°C.
Wow!
The lights from St. Helier reflected in wet sand in St. Aubin's Bay doing a great impersonation of Jersey's climate stripes. What colour will our stripe for 2020 be?
#ShowYourStripes
Howard Davis Farm recorded a total of 328.7mm of rain in November 2023. This is provisionally the highest amount of rain reported at any of our observing sites in Jersey, for any month across all the years that we've been observing the weather.
It's been our hottest 2019 day so far, which is a fantastic stat for the 1st day of meteorological summer!
27.7 degrees Celsius was recorded at the Maison St Louis Observatory.
The day isn't over yet, but we might just have been the hottest spot in the British Isles today.
'Show your Stripes' day

- here are Jersey's Stripes, using data from the Maison St. Louis Observatory where temperature and rainfall records began in 1894.

Our spies were out and about on the north coast tonight and report an accumulation of around 2cm on roads in Trinity. Thanks to John Searson for the brilliant photo.
Storm Ciaran briefly brought winds reaching Hurricane Force 12 to the Island, gusts recorded at St Helier Harbour up to 83kt/96mph peaking around 4:30 a.m. this morning. Jersey Airport recorded a gust of 88kt/101mph. Coastguard at St. Helier recorded a gust of 89kt/102mph.
We’ve seen some lovely photos of the spectacular sunrise this morning, here’s a time lapse video over St Aubin’s Bay, wonderful colours and passing cloud!
What a glorious weekend we're having! The temperature has reached 16.9°C at the Maison St Louis Observatory so far this afternoon, a whopping 8 degrees above average and the highest February temp ever recorded in Jersey! The previous record of 16.2°C was set way back in 1948.
A record breaking day yesterday. The July maximum temperature record at Maison St Louis Observatory was broken. The temperature of 36.0°C at Jersey Airport equaled the all time record for the island. Here are the official figures from our recording sites.
A very dramatic thunderstorm last night, and quite an unusual one.
So often we see thunderstorms lose their energy as they cross the cool Channel waters.
But this one actually blossomed around Les Minquiers, with cumulonimbus clouds almost doubling in height in just half an hour.
What an eventful night with two bands of heavy thundery showers moving across the island. The map below () shows all the lightning strikes which affected the island over the last 24 hours.
Fractionally short of being a June record breaker. Today's max temperature at Maison St Louis Observatory was 32.7°C.
To put that into context, our hottest ever June 25th was 32.9°C and our hottest ever June day was precisely 33.0°C.
A gorgeous start to 2021. The max temperature recorded at the Maison St Louis Observatory was only 5.8°C, but it probably didn't feel as cold as that, due to lengthy spells of sunshine and barely a breath of wind.
Thanks to Phoebe Sandamali Haseman for this lovely photo.
The sand at Greve de Lecq is repositioned by the weather, waves and tides on a daily basis, often quite dramatically, like a miniature-model of the geological processes that have shaped the earth.
Rain, rain, go away, come again some other day! 🌧️☂️☔️
The last 6 weeks has been particularly wet and we've now had 43 consecutive days where rain has affected the island, although on one of these days (22nd October) only negligible rainfall amounts were recorded.
What a beautiful winter's day, wall-to-wall sunshine, a light southeast breeze and the temperature reaching 8.6°C at Maison St. Louis Observatory. All change for tomorrow though with cloudier skies expected across the Channel Islands on Saturday.
When you see 'Sunshine and showers' in the forecast then you can expect plenty of these beauties.
You just have to remember to look for them...
-The sun must be behind you and the rain in front
-The lower the sun, the bigger the bow

July 2022 in Jersey - 3 records for Maison St Louis Observatory: driest July, hottest day & warmest night since records began in 1894. Jersey Airport, with records back to 1951, also recorded its hottest day & driest July, as did Howard Davis Farm, with records back to 1932.
What a glorious day! It was a little cloudy this morning, but otherwise there was plenty of sunshine around, no showers in the end and the temperature reached 18.3°C at Maison St. Louis Observatory this afternoon
Following Monday's record breaking maximum temperature we've been looking back at the top 25 hottest days that we've ever recorded in Jersey, and where they sit in time.
The maximum temperature today at Maison St Louis Observatory reached 31.9°C 🌡️ - making it the hottest
#jerseybattleofflowers
since it's debut in 1902! Well done to all involved!
Today, the Jersey Climate Stripes were unveiled, that use temperature records from the past 126 years, collected at the Maison St. Louis Observatory.
Today’s maximum temperature was 22.5°C.
#showyourstripes
Just in case you missed sunrise this morning, it was certainly a stunning view.
Today: Rather cloudy but bright with some hazy sunshine and the risk of a shower until late evening. Fair spells overnight perhaps with some mist and hill fog. Max: 25°C.
As Bank Holiday Weekends go it probably couldn't get any better. Cloud free skies, light winds and top temperature today of 23.4°C Rewind and repeat tomorrow and with the UV high at 7 take care in the sun.
Maison St. Louis Observatory is presented with a fantastic Jersey Climate Stripes scarf knitted by

You may have seen the striking parhelia (or 'sun dogs') either side of the sun this evening. These are caused by refraction of sunlight by the ice crystals in the high cirrostratus cloud that is moving across the area at the moment.
Low pressure lies to the west of the UK with high pressure to the east acting like cogs in the atmosphere, drawing up very warm air from France and Spain. The temperature in Jersey is likely to reach 30°C tomorrow, which would make it one of the warmest September days on record.
Can you help? We've been doing some work at the Maison St. Louis Observatory in Jersey with
@loveheritage
we've discovered this weather instrument. We're fairly confident we know what it is and what it does but can anyone help? We believe it was hand built here in the Observatory
In this afternoon's sunshine and despite the breezy weather, the temperature rose to 20.8˚C at Maison St Louis Observatory - all in all, very pleasant for the Jersey Airshow.
The cloud doggedly stuck with us today, only clearing to some hazy sunshine late this afternoon, with a maximum temperature of 13.8°C recorded at Maison St Louis Observatory.
Thanks to Paul Aked for the evening photograph.
High tide at 8.02am this morning, at a recorded height of 12.04m, a little higher than astronomical predicted height due to low pressure.
As a result of recent cold weather the sea temperature is currently 6.3°C, the coldest local sea temperature since February 2010.
A maximum temperature of 29.6°C was recorded at Maison St Louis this afternoon, the warmest day in Jersey for over a year (since 20th June 2017 to be exact). A degree or so 'cooler' tomorrow, but plenty more sunshine in store with the UV levels again expected to reach 7.
With the high cloud that's been around over recent days there's been some pretty spectacular sunsets and sunrises. This was the scene at St Ouen's Bay around dusk last night.
@VisitJerseyCI
With the temperature reaching 25.8°C at Maison St. Louis Observatory this afternoon, Jersey has just had it's 2nd hottest October day on record! This is also the latest date in the year that we've exceeded 25°C in a climate record that stretches back to 1894.

An almost cloudless winter's day, with excellent visibility and mostly light winds. The top temperature at the Maison St Louis Observatory was precisely 7°C.
Summer 2022 in Jersey - Hottest summer on record, and 2nd sunniest. Daily temperature reached 30°C or more on 8 days, the most on record for a single year.
In glorious sunshine, the temperature peaked at 29.4˚C at Maison St Louis Observatory this afternoon. That's made it the warmest day in Jersey since 21 July 2021, when the thermometer reached 30.1˚C.
A very warm day for the end March in Jersey today, with the temperature reaching 18.8°C at Maison St Louis Observatory late this afternoon. Expect something a little warmer tomorrow!
A day of unbroken sunshine and a southeasterly breeze were the perfect combination for a maximum temperature of 29.8°C at Maison St Louis Observatory this afternoon.
Today the temperature reached 8.4°C at the Maison St. Louis Observatory, with a colourful sunset, through thick cirrus cloud to round off the afternoon.
Today: Long sunny periods. Just a smallest chance of a brief light shower. Max: 10°C.
Wind today: West to northwest light F2 to 3, backing west to southwest moderate F4.
