Weather Data for November

Megan Naish, 5 December 2025

Hi Bulb Buddies,

I would like to say a huge thank you to all schools who have been uploading their weather data to the website so far! There has been very mixed weather this November, so it is interesting to see what you have all logged.

The MET Office has noted that November 2025 has brought very variable weather across the UK, with higher-than-average rainfall. This month the UK rainfall was 31% above average for November, making it the wettest month of 2025 so far!

This November Storm Claudia brought heavy rainfall, especially to England and Wales, with the MET Office reporting that the Midlands, Lincolnshire, and Yorkshire saw more than double their average November rainfall. This rainfall resulted in flooding and disruption in some areas, which is reflected in your comments!

The temperature this November was also varied, where the month began warmer than usual but very quickly dropped in temperature during the second half of the month. Many schools have mentioned this change in their comments, with some seeing frost and short bursts of snow!

Let’s take a look at your comments to see how the project is going in schools across the UK.

Many Bulb Buddies have made some great weather observations:

Church Cowley St James CE Primary

Bitter cold week but glorious sunshine on Friday.

Cornist Park C.P

The start of the week began really mild. As the week has gone on the rain has become more persistent resulting in 12mm of rainfall while we were in school on Friday.

Mary Immaculate R.C. School

On Tuesday 4th November we had really heavy rain. Resulting in our playground flooding and lots of children and staff struggling to get home after school One of our teachers in Tenby had no water in her house for the evening.

Pil Primary School

There has been a lot of rain this week.

Professor Plant:

It is great to see so much detail in your comments, noting how much the weather has changed in just one week. The rainfall over November has been great for helping your bulbs grow!

However, storms can be very disruptive, so thank you for sharing the impact that the storm had on your schools and at home.

Professor Plant:

It is so interesting to read about the changes in temperature that you have observed over November, with some of you even seeing some snowfall! Continue to log these details, as it will be exciting to see what temperatures December brings.

-

We have even had some Bulb Buddies reporting on some plant growth already:

Rhayader Primary

Our mystery bulbs have started growing, as have some of our other pots.

St Patrick's RC Primary - Newport

The temperature dropped immensely over the weekend. We also have begun to see early growth in our crocus plants.

Professor Plant:

It is very exciting to hear that some schools have already started to see some plant growth! Well done for logging this and keep watch over your plants to see what happens next.

I have loved reading through your comments and observations and seeing all of your data being uploaded. Keep up the amazing work Bulb Buddies, and I look forward to seeing what happens next over December!

Weather Records Start from 3 November!

Megan Naish, 30 October 2025

Hi Bulb Buddies,

I want to say a big thank you to all of the participating schools who worked hard planting bulbs for the project. Together we planted over 18 thousand bulbs across the UK and from the photos I’ve seen, it looks as though everyone had great fun doing it! 

All schools taking part in the project will be collecting weather data from the 3rd of November until the 27th of March. They will be uploading these records regularly to the Amgueddfa Cymru website, along with comments and weather observations. We'll be learning a lot together over the school year!

Step 4: Keeping weather records (November - March)

Resources are available on the website that explore different aspects of the project, including ideas for additional experiments and guides to making short videos for the Bulbcast competition!  

Step 3: Optional hands-on weather and gardening themed activities

I'll be sure to share more photos and comments from schools to the Blog in the coming weeks. 

Keep up the good work Bulb Buddies,

Professor Plant

Planting Day 2025

Penny Dacey, 20 October 2025

It’s Planting Day for 178 schools across the UK today!
More than 18,000 bulbs will be planted by over 7,000 primary school scientists as part of this exciting outdoor investigation exploring how a changing climate affects the flowering dates of spring bulbs.

Follow the project and the experiences of our Super Scientists through this blog or on X at @ProfessorPlant.

Project team members are visiting several schools today to celebrate the 20th anniversary of Planting Day, and we look forward to receiving updates and photos from schools across the country.

Competitions and Creative Projects

Schools are invited to share their photos and creative media for our Planting Day Photo Competition. We’ll showcase the winning entries here next month!

We’re also running the Bulbcast Competition, where participating schools create short videos highlighting their favourite parts of the investigation. Resources to support this can be found here.

And for this special anniversary year, we’re thrilled to launch a Name the Daffodil Competition! Participants can suggest names for a brand-new daffodil variety commissioned to mark the 20th year of the investigation. You can see what our daffodil looks like in the attached image and find inspiration and guidance in the resource linked here. We can’t wait to see your entries!

A Special Display at St Fagans

The fantastic Gardening Team at St Fagans National Museum of History have been joining in the celebrations too! They’ve planted a commemorative display and created a beautiful woven planter for the project, which you can see in the attached images.

Get Involved

Feeling inspired? Why not plant some bulbs this October and share your images with us!
We’ll also be hosting free planting activities for families at St Fagans National Museum of History and National Museum Cardiff, where visitors can learn about plants and adopt their own baby bulbs. Find out more about how to join these sessions on our website.

Once schools have adopted and planted their bulbs, they will set up outdoor weather stations. From 3 November, they’ll collect daily weather readings every day that they are in school and upload these weekly to the Amgueddfa Cymru website. You can follow their progress here.

We’re so excited to get this year’s project underway and to share the journey with you all.

Here’s to another year of discovery, teamwork, and blooming science!

The Great Big Green Week Climate Quiz!

Penny Dacey, 12 June 2025

Hello Bulb Buddies!

Climate Cymru’s Great Big Green Week has been running since 7th June, with people across Wales (and the UK!) coming together to help protect our planet. There are fun activities, cool events, and lots of ways for you and your school to get involved.  

What is The Great Big Green Week?

The Great Big Green Week is the UK’s biggest celebration of community action to tackle climate change and protect nature. All sorts of people are making swaps and taking small steps that make a difference to the planet. From planting flowers to picking up litter, every action counts! 

Who are Climate Cymru?

Climate Cymru is a movement made up of hundreds of organisations and thousands of people from all across Wales, working together to tackle the climate and nature emergencies. By bringing together voices from every part of Welsh society (schools, businesses, community groups, and more) Climate Cymru makes sure that everyone is heard and that leaders take meaningful action for a greener, fairer future for Wales and the planet. 

What is the Spring Bulbs for Schools Investigation?

The Spring Bulbs for Schools Investigation engages thousands of children from across the UK every year in a scientific study around the effects of climate change on the flowering dates of Spring Bulbs. Pupils adopt, care for and study their plants. They take weather readings every day that they are in school between November and March and share their findings to the Amgueddfa Cymru website. Our reports from last year’s investigation can be found here, along with many other educational resources. The bilingual reports from this year will be published in early July. 

If you’ve participated in this year’s project by planting and growing spring bulbs, then you’re already a climate champion! If you’re looking for a Great Big Green Week Action that your school could take, applications for schools in Wales are open, and you can apply here! 2025-2026 will be the 20th anniversary year of this fantastic project!

Who are The Edina Trust?

The Edina Trust are partners and funders of Amgueddfa Cymru’s Spring Bulbs for Schools Investigation. They are a charity that helps primary schools with science by offering non-competitive grants for exciting projects like gardening, science resources, and outdoor learning. This year, schools in Denbighshire, Newport, and Torfaen can apply for Edina Trust grants, so if your school is in one of these areas, you’re guaranteed to get funding to help develop your science adventures! Find out more here!

Try the Climate Quiz by Amgueddfa Cymru!

To celebrate The Great Big Green Week, Amgueddfa Cymru (National Museum Wales) has created a special Climate Quiz just for you. It’s part of the Spring Bulbs for Schools Investigation, and it’s a fun way to test your knowledge about the climate and how we can all help protect nature.

  • What's the difference between weather and climate?
  • How much of the UK's total energy comes from renewable sources?
  • Why are insects important for the climate?
  • What actions could you take to help?

Find out by taking the quiz with your classmates or family. You might be surprised at what you learn!

Let’s Be Planet Protectors!

Remember, even small changes can make a big difference. By joining in with The Great Big Green Week and the Climate Quiz, you’re helping to raise awareness of how we can all look after the Earth for animals, plants, and people everywhere.

Share what you’ve learnt:
