Step-by-Step Rainstorm Registration Guide:

  1. Make sure you have a student account on this website,, since your local Splash website’s account won’t allow you to register for Rainstorm. Start by clicking the drop down arrow on the login bar (at the top right of the page) to do so. There are separate accounts for parents and educators.
  2. Be sure you and your parent/guardian have reviewed and agreed to our Codes of Conduct.
  3. If you have already made an account but have not registered, click here.
  4. In the spirit of fairness to all students who wish to attend Rainstorm, registration involves a lottery system that is run in three phases: a program lottery, a class lottery, and a first-come first-serve class sign-up.

Registration Timeline for Rainstorm Summer 2021

Now! - TBA: Student lottery phase

Register for an account and choose to enter the student lottery. Only winners of the student lottery may register for classes in the lottery and first-come first-serve phases.

TBA- TBA: Class lottery phase

If you have been notified that you have won a spot in the lottery, you can rank classes by preference during this window.

TBA- TBA: First-come first-serve phase

After the class lottery has determined which classes students are in, they may have empty slots they want to fill. They can now choose to join classes that have spots remaining on a first-come first-serve basis.

August 14th- August 15th: Summer Splash!


Unfortunately, we expect more students to register for the lottery than we can admit to Rainstorm. If you register, we expect you to attend any classes in which you enroll. In the event you cannot make a class, please email to let us know in advance so we can give your slot to another student!
