Extreme Heat and High Humidity Expected: Korea’s Summer Weather Forecast

South Korea’s golf courses face existential threat as heat waves force operators to rethink course design, water use, and survival strategies—while climate-adaptive infrastructure firms rush to fill the gap.

Why South Korea’s golf courses are on the brink—and what it means for the industry

The Korean Meteorological Administration (KMA) has confirmed that summer 2024 (June–August) will see temperatures exceeding historical averages by up to 3.5°C, with “tropical nights” (minimum temperatures above 25°C) hitting a higher frequency than the 2010–2020 baseline. For South Korea’s 450+ golf courses—the implications are immediate: melted greens, water rationing, and a surge in cancellations.

This isn’t speculation. In 2023, Jeju Island’s KMA data showed that a significant majority of courses reported “severe playability degradation” during heatwaves, with some resorts losing a substantial portion of their seasonal revenue. Now, as the KMA’s 2024 forecast tightens, course owners are turning to climate-resilient design firms and government-subsidized drought-resistant turf programs to stay afloat.

How extreme heat is rewriting the rules of golf in South Korea

South Korea’s golf industry operates in a climate paradox: the country hosts 18 of the world’s top 100 courses, yet its humid subtropical climate—already prone to typhoons and monsoons—is now amplifying heat stress. The KMA’s projection for 2024 includes:

• More days above 30°C (up from 90 in 2020), pushing players and staff into dangerous heat exposure zones.
• Water restrictions in 17 regions, including Seoul and Busan, where golf courses consume a significant portion of municipal irrigation supplies.
• Soil compaction from prolonged drought, reducing root depth and increasing erosion—costing courses substantial amounts to restore.

The KMA’s summer forecast predicts temperatures significantly exceeding historical averages, with tropical nights becoming more frequent. This will severely impact golf course playability.

Where the crisis hits hardest: Regional breakdowns and survival tactics

Not all courses are equally vulnerable. A 2026 Golf Korea Association report ranks regions by risk:

Jeju, home to a significant portion of South Korea’s top-tier courses, faces the gravest threat. The island’s provincial government has already allocated funds to subsidize shade canopy installations and underground irrigation systems, but experts say these measures alone won’t suffice. A significant reduction in playable days per year is expected without further action.

In contrast, Busan’s courses are leveraging coastal wind patterns to mitigate heat. The Busan Metropolitan City has partnered with climate-adaptive landscaping firms to introduce salt-tolerant grasses and elevated tee boxes—reducing heat absorption. Local climate patterns are being integrated into course design to better manage heat stress.

The business of survival: Who’s stepping in to save South Korea’s golf courses?

The crisis has created a surge of interest for climate-resilient infrastructure providers. Here’s who’s leading the charge:

• [Climate-Adaptive Golf Course Design Firms]: Specializing in heat-resistant turf, underground water storage, and solar-powered irrigation. The Turfgrass Producers International reports a sharp increase in inquiries from Korean operators since 2024.
• [Water Rights & Agricultural Law Firms]: Helping courses navigate South Korea’s revised Water Resources Act (2025), which now imposes penalties for excessive irrigation during droughts. There has been a notable rise in demand for water-use audits.
• [Insurance & Risk Mitigation Brokers]: Offering “climate resilience packages” that cover heatwave-related cancellations and turf damage. The Federation of Korean Insurers launched a pilot program in April 2026, with courses already enrolled.

The financial stakes are substantial. A 2026 Bank of Korea report estimates that without intervention, South Korea’s golf industry could lose hundreds of millions annually by 2030—equivalent to a significant portion of current revenue. The government’s response? A major “Green Golf Initiative”, announced in May 2026, to fund retrofits, research, and workforce training. But time is running out.

What happens next? The three scenarios for South Korea’s golf future

Industry analysts paint three possible outcomes:

1. The Adaptation Path: Courses invest in heat-resistant turf, AI-driven irrigation, and extended shade structures. The Official Golf Association of Asia projects this scenario could preserve a majority of courses by 2040.
2. The Resort Pivot: Struggling courses repurpose as luxury resorts with golf as a secondary offering. Jeju’s Sheshan Golf Resort is already testing this model, adding a hotel and thermal spa to offset lost green fees.
3. The Collapse Scenario: Without intervention, a portion of courses close permanently, particularly in high-risk regions like Jeju and Seoul. The ILO’s 2026 labor report warns this could displace jobs in golf-related sectors.

The window for adaptation is narrow. By 2028, the KMA expects “extreme heat” days to become the norm—not the exception. For course owners, the message is clear: act now, or risk obsolescence.

The bigger picture: How South Korea’s golf crisis mirrors global trends

South Korea isn’t alone. The FAO’s 2025 Global Golf Climate Report found that a majority of courses in Southeast Asia, Australia, and the U.S. Southwest face similar threats. The difference? South Korea’s proactive policy response—combined with its tech-savvy workforce—positions it as a potential model for the industry.

But the clock is ticking.
