1 August 2025 - Registration deadline

To take part in the first forecasting period of the AI Weather Quest (SON: September–November 2025), teams must register by 1 August 2025.

Only teams registered by this deadline will be eligible for participation and considered for the annual awards.

Registration will remain open for later forecasting periods, but 1 August is the only chance to join from the start and compete across the full cycle.
