Pages: 9 (including cover and credits). Sizes: A4 (210 × 297 mm) and US Letter (8.5 × 11 in), both PDFs included in one zip.

Printing: Print at 100% / actual size on A4 or US Letter. Inside pages use light backgrounds and print well in black and white; covers are dark, so start from page 2 to save ink. Cards: print double-sided, flipping on the long edge, on thin card.

Every fact is checked against Met Office, NOAA/National Weather Service and NASA web pages (checked 27 Oct 2026) and the sources are listed on each pack’s credits page. Facts that can change, such as yearly counts and averages, are printed with that date. Where two official pages give different figures, both are shown with their source. Photos are public-domain images from the NOAA Photo Library and NASA (the 1902 Eiffel Tower photo, by Gabriel Loppé, is from the NOAA Photo Library), via Wikimedia Commons; drawings, puzzles and layouts are REALLYBYTE’s own work. Not endorsed by the Met Office, NOAA or NASA. This is an educational resource, not official safety advice: always follow your local weather service’s warnings.

Licence: personal and single-classroom use. You may print as many copies as you need for your own family or your own class, and share it with your class through a password-protected platform. Please don’t resell, re-upload or share it publicly. For school-wide use, please email info@reallybyte.com.
