So, summers over. Weren't those four days glorious though! Who know's, maybe the sun will come back, but between now and the end of May, the forecast isn't great.
With that in mind we've compiled a list of some of the best indoor activities across NI.

Armagh Planetarium

First open in 1968 the Armagh Planetarium has become a world-renowned astronomical educational establishment, and its purpose remains to bring astronomy to a wider audience.
The Planetarium states that its aim is to "demonstrate to our visitors the amazing objects that exist in the cosmos, but to do it in such a way that they do not see our efforts as formal teaching. We call this 'Learning by Stealth'. When they are prompted to ask questions, they are engaging in the learning process.
"All of our school theatre shows are interactive, so that presenters and pupils take an active part in the show. Follow up tasks back in the classroom are facilitated by downloadable PDFs and astronomical factsheets for teachers to use as supplementary teaching material."
The Planetarium has a range of shows suitable for all the family, including:
Edge of Darkness A full dome show featuring amazing scenes of places never before seen gathered by key space missions that culminated with groundbreaking discoveries in 2015.
Sun, Moon & Stars A lively interactive show designed to introduce children to our Sun, Moon and stars.
Astronaut The exploration of space is the greatest endeavour that humankind has ever undertaken. What does it take to be part of this incredible journey? What does it take to become an astronaut?
Exploding Universe Out of devastating events in the cosmos comes new creation. Explosive phenomena are responsible for the way we see the Universe today.
The Accidental Astronauts Follow the adventures of Sy and Annie, and their dog Armstrong, as they embark on an unexpected journey into space!
Little Yellow Star Free live nursery age show with a presenter to guide your little ones.
Due to the darkness and sound levels some shows are only suitable for children of six years and above. Children under six years old will not be permitted to these shows. Check the full show descriptions on the website (link below) for age ranges and prices.

Ulster Museum, Botanic Gardens and the Palm House

To locals the Ulster Museum could be easily forgotten; maybe you haven't been since you were a child and remember it as being a bit rundown. Well, if so, you should definitely revisit.
Following extensive renovations, the museum is better than ever. You'll come "face to face with dinosaurs, meet an Egyptian Mummy and see modern masterpieces..."
Entry is free however donations are welcomed - to almost their entire museum and its exhibitions. Currently you'll find work by Rembrandt – on loan from the National Gallery – and Rep-Tails, a "unique hands-on experience with reptiles, tarantulas, scorpions and insects. And of course the museums resident displays of art, historical artefacts and collections.
"As Northern Ireland's treasure house of the past and present, the museum is home to a rich collection of art, history and natural sciences and free to all visitors. From Ireland to the South Pacific, ancient relics to hands on activities, the museum offers something for everyone from the simply curious to the enthusiast."
Open Tuesday to Sunday, 10:00 to 17:00.
