The summer giving slump is real — and it starts earlier than you think

Giving drops. Donors are distracted. Staff takes vacations. Interns handle communications. The editorial calendar — if there is one — gets thin.

By August, a lot of organizations are staring at flat numbers and wondering what happened. The answer, almost always, is that summer didn't sneak up on them. They just didn't prepare for it in April.

Research from the Fundraising Effectiveness Project consistently shows that Q3 — July, August, September — is the weakest quarter for charitable giving for most nonprofits, particularly small and mid-size organizations.

Giving in Q3 can run 20–30% below Q2 and 40–50% below Q4 for organizations that depend heavily on year-end campaigns.

That gap isn't inevitable. But closing it requires decisions made now, not in July.

It's not just about donor behavior. It's about organizational behavior. Here's what tends to happen between June and September:

Staff capacity drops. Vacations overlap, coverage gets thin, and the donor communications that require a human touch get delayed or deprioritized. The thank-you calls don't get made. The mid-year impact report gets pushed to fall.

Content gets generic. When capacity is stretched, communications become transactional — event invites, appeals, receipt acknowledgments. The relationship-building content that keeps donors warm gets replaced by the kind of messaging that feels like broadcasting.

Momentum stalls. If a donor gave in April and doesn't hear from you in a meaningful way until October, that's a six-month silence. The reactivation math gets harder with every passing month. By the time your year-end appeal lands, they're cold.

They treat May and June as relationship months, not ramp-down months.

That means a mid-year impact update that goes out before donors have mentally checked out for summer. It means a thank-you touch in June that isn't an ask — just a story, an update, a "here's what your giving made possible so far this year."

It means a monthly giving nudge in May that reminds recurring donors why they set up that recurring gift in the first place.

It also means keeping the content calendar alive — not with daily posts or elaborate campaigns, but with consistent, high-quality communication that signals your organization didn't go on autopilot.

Here's what most organizations miss: year-end fundraising success is largely determined by what you did with donors between January and September.

Donors who heard from you meaningfully three or four times over the summer — with stories, updates, genuine human contact — respond to year-end appeals at significantly higher rates than donors who only heard from you when you needed something.

The year-end campaign isn't the relationship. It's the harvest of the relationship you built all year.

You don't need a 12-week summer campaign. You need three things: a mid-year impact update with a specific story and a real number, a plan for how you're handling lapsed monthly donors before August, and a content cadence — even just one post and one email per week — that keeps your name in front of the people who already gave you their trust.

The organizations that show up consistently in May and June are the ones whose donors pick up the phone in November. That's not a coincidence. It's a system — and systems are buildable.

That's what Nonprofit Bestie is for. If you're heading into summer without a clear donor communications plan, I work with small and mid-size nonprofits to build the structure that keeps relationships warm when organizational capacity is at its lowest. The content calendar, the mid-year touchpoints, the monthly giving retention pieces — the work that makes Q4 feel less like a scramble and more like a payoff.

Summer doesn't have to be the slow quarter. It just requires deciding now that it won't be.
