August 2025... A month which was split with notable extremes. Cool and windy for some but hot and sunny for others. We had an exceptional wind storm early in the month (Floris) which impacted northwest Europe and strong heat made return for many, especially in the west. Southern and western areas ended up on the warmer side for the month overall while the north and east ended up cool. A wet month for the Adriatic with Podgorica in Montenegro recording nearly 400% of the average rainfall. Drier than normal in the west with places like Lisbon only receiving 11% of average rain.

Another insane month for Northeast Asia. Tokyo came in nearly 3°C hotter than average for the month overall.

north America was split hot in the west and cool in the east.

Australia was widely cooler than average. Notably wet in western half of the country.

Africa hotter than normal in the north, mixed to slightly cooler than average in the south with heavy rains for Namibia, Botswana and far northern parts of South Africa.

South America was widely cooler than average away from Central/Southern Argentina.

July 2025 will certainly be remembered by Northern Europe. Record breaking length and strength to the heatwaves in Fennoscandia.

Eastern Asia has had yet another atrociously hot month. What a dreadful summer over there

Parts of Canada, India, Australia and swathes of South America have had below seasonal average temperatures.

However, global average temperature was the 3rd warmest July on record.

Storm Floris today is no joke for Scotland. 90+ mph (145+ km/h) wind gusts possible for some, this would be unprecedented for August. Stay safe.

Extraordinary heat in June. Both on land and at sea. June 2025 is the hottest June on record for parts of Western Europe with record setting sea surface temperatures in the Western Mediterranean.

A marked swing for Spain after the cool rainy conditions in Spring. Northern Europe was notably windy and wet and relatively rather cool.

Heat made headlines in North America and large parts of Eastern Asia with most places hotter than the seasonal average. India is again cooler than average though.

Notable cold month in South America... Argentina, Paraguay, Uruguay and South Brazil were wildly 2-3 °C colder than long term average. Impressive. Much of Australia away from the west and south were also relatively cool.

Ok... This was not on my bingo card. Not ever.

Nearly 5 years ago during the dark lockdown days of Covid , a very exciting opportunity came along.

Sony PlayStation were looking to build a platform which would revolutionize the way weather and climate data and projections could be visualised and communicated. I was naturally very excited about this project and got stuck in. From scientific input & script-writing to visual feedback and product testing... It has been quite the journey.

I am thrilled to announce ClimateStation™️ is now live!

The VR immersive experience is something new to me and I am struggling to avoid the cliche 'mind-blown'. But wow 🤯

I was working with a fantastic team over the years and enjoyed every moment of it.

May 2025... A quick tour around the world.

Europe - strong split:
Cold in the east, warm in the west.
Reykjavik (Iceland 🇮🇸) was +1.8°C had the strongest positive anomaly in Europe.
Vilnius (Lithuania 🇱🇹) was -3.1°C colder than average (strongest negative anomaly in Europe),
with Minsk (Belarus 🇧🇾) at -2.9°C and Warsaw (Poland 🇵🇱) at -2.7°C not far behind.

Middle East — among the warmest globally:
Dushanbe (Tajikistan 🇹🇯) recorded +4.3°C above average,
Tehran (Iran 🇮🇷) was +4.1°C,
and Ashgabat (Turkmenistan 🇹🇲) came in at +2.9°C — all significantly warmer than their May norms.

North America saw a split:
Strong warmth in the west and across Canada 🇨🇦,
with countries around the Caribbean and Gulf of Mexico also running warmer than average for May. Central portions of the US up through the Midwest were relatively cool.

India 🇮🇳 experienced a notably cooler month:
New Delhi (India) was -1.0°C below the 1991–2020 average.
Meanwhile, heat stretched east from the Middle East into much of China 🇨🇳,
but Beijing (China) stood out as a cooler exception, at -1.5°C below average.

Africa showed a north-south contrast:
The warmest anomaly was in Juba (South Sudan 🇸🇸), at +1.7°C above average.
One of the coolest relative to normal was Gaborone (Botswana 🇧🇼), at -1.9°C below average — especially notable for inland southern areas.

South America leaned warmer than normal:
Asunción (Paraguay 🇵🇾) was the warmest capital relative to average, at +2.2°C.
Brasilia (Brazil 🇧🇷) was one of the cooler spots, at -0.8°C below May average.

Australia & New Zealand:
Western and eastern parts of Australia 🇦🇺 were warmer than average,
while central and northern areas were relatively cooler.
New Zealand 🇳🇿 also experienced a warmer-than-usual May.

🔥 June is already shaping up to be quite a beast... stay tuned.

🌍 April 2025 Global Climate Snapshot

April 2025 was the 2nd warmest April on record globally, with temperatures averaging 1.51°C above pre-industrial levels. It's the 21st time in 22 months global temperatures exceeded the 1.5°C threshold.

🌾 Europe:

April 2025 ranked as the 6th warmest April on record for Europe.

NW Europe stayed exceptionally dry — some areas may be heading for their driest spring in over a century. 🌵

Temperatures were above average across most of the continent, except the far SE (e.g., Turkey, Bulgaria, Romania).

🇪🇸🇵🇹 Spain & Portugal logged another wet month — March + April totals are particularly notable, contrasting sharply with dry northern regions.

🇺🇸🇨🇦 North America:

A tale of two countries: Cold across Eastern Canada, while extremely warm conditions dominated much of the U.S.vmost pronounced anomalies were in the south.

South America 🔷

Widely colder than long-term average and wet for Paraguay 🇵🇾 and southern portions of Brazil 🇧🇷

🌡️ Asia & Middle East:

Very hot conditions extended from the Middle East through Central Asia into China.

🇨🇳 China had its 3rd hottest April on record. Worth noting that hottest April for china was set last year in 2024.

🌧️ Africa:

Southern parts of the continent saw a notably wet April.

March... cool and very wet for some. Very warm and dry compared to average for other.

The moon appears to be blocking the sun a bit...

2024 was the hottest year in record for global average temperature. Data in this series from NASA stretches back to 1880. The past 10 years were the warmest 10 years on record.

Despite a shift from El Nino to weak La Nina, global average temperatures remained exceptional. Human activities, primarily linked to releasing carbon dioxide into the atmosphere remains the main driver here.

It is ironic that the summary of data is realised while some parts of the populated northern hemisphere are experiencing exceptional cold and snow. More on that soon...

Oh, happy new year!
