You can’t predict the weather, but you can use it to grow your savings.

A new savings challenge takes the guesswork out of setting money aside by tying your deposits to the daily forecast. All you have to do is check your weather app and save an amount based on the day’s temperature.

Here’s how it works.

The weather savings challenge, explained

The weather savings challenge is a strategy that uses the daily temperature to determine how much money you save. Instead of choosing a fixed amount to deposit each week or month, your savings contribution changes based on the weather forecast.

For example, say you check the weather, and it’s going to be a high of 72 degrees that day. You would then deposit $72 into your savings account.

Of course, making a daily deposit won’t be realistic for most people. The good news is that the weather savings challenge is flexible, allowing you to decide when and how to play.

For example, you may want to deposit your savings on the first of every month. You could also choose to deposit the daily low instead of the high, use the last digit of the temperature (72°F = $2), or save the temperature in cents rather than dollars (72°F = $0.72).

Again, when it comes to participating in the weather savings challenge, the rules are up to you. The key is choosing a version of the challenge that’s realistic and sustainable.

Benefits of the weather savings challenge

The weather savings challenge offers a simple and flexible way to build your savings without overhauling your budget.

One of the biggest benefits of the weather savings challenge is that it helps make saving consistent. Many people struggle to save because they feel they need to set aside large amounts of money to make a difference. By focusing on small, manageable deposits, the challenge encourages regular contributions that can add up over time.

The challenge can also make saving more engaging. Checking the weather is already part of many people’s daily routine, so tying savings to the forecast creates a built-in reminder to transfer money into a savings account. This can help savers stay motivated and avoid forgetting about their financial goals.

And finally, a big benefit of this savings challenge is flexibility. Participants can customize the rules based on their budget, local climate, and savings goals.

Drawbacks of the weather savings challenge

One key drawback of this strategy is its lack of predictability. Because your savings deposits are tied to the weather, it can be difficult to estimate how much you’ll save over the course of a month or year. That can make it harder to plan for specific savings goals with a set deadline.

The bottom line

This savings challenge may not offer the structure needed to meet long-term goals like saving for retirement. However, it can be a fun way to kickstart your savings journey and keep you motivated.

But remember, there’s no one right way to save money. The key is making it a habit. So, if turning saving money into a game helps you stay on track, there are several other challenges you can try until you find one that sticks:
