August lake water in North Texas runs in the upper 80s°F — the warmest of the year, never too hot to surf. The trick is booking a glassy morning session before the afternoon heat, and the late-summer lakes are quieter than you'd think.
Wakesurfing in North Texas in August: Is the Water Too Hot or the Best Time to Go?
Spoiler: the lake never gets "too hot" to surf — but the sun does have opinions. Here's how locals ride the warmest water of the year in comfort.
The short answer
August is one of the best months of the whole season — if you go in the morning. North Texas lake water runs in the upper 80s°F in August, the warmest it gets all year. That's bathwater: no wetsuit, no cold-shock gasp when you fall, and little kids can splash around between sets. The water is never the problem.
The afternoon air is what you plan around. Book a sunrise-to-noon session and you get glassy water, cooler air, lighter boat traffic — and you're back on shore before the 100° part of the day even clocks in.
Every August we hear the same question: "Isn't it too hot to be out on the lake?" And every August, the people who book morning sessions come back sunburn-free and grinning, wondering why the lake was so empty. Late summer is a local secret — the July 4th crowds are gone, the water is at its warmest, and the early light on a glassy lake is flat-out gorgeous. Here's exactly how to do August right.
How warm is the water, really?
Warm enough that "getting wet" is a feature, not a cost. Here's roughly what surface temps look like across the season on North Texas lakes:
| Month | Typical surface temp | What it feels like |
|---|---|---|
| May | 70–75°F | Refreshing — brisk on the first fall |
| June | 78–83°F | Comfortable all day |
| July | 84–88°F | Warm — nobody hesitates to jump in |
| August | 86–90°F | Bathwater — the warmest of the year |
| September | 80–85°F | Still lovely — season winding down |
Temps vary a bit by lake and by cove — deep, clear lakes like Possum Kingdom run a touch cooler than shallow ones. Every one of the ten lakes we serve is comfortably swimmable all August long.
Why mornings win in August (three real reasons)
A sunrise session gets you…
- Glassy water. Wind and boat traffic build through the day. Right after sunrise, the lake is usually a mirror — the smoothest, most forgiving wave you'll ride all summer.
- 15–20 degrees of relief. A 7 a.m. start means air in the low 80s instead of triple digits. You'll do your surfing in the coolest, prettiest part of the day and be at lunch by the time it's roasting.
- A quieter lake. August weekends are noticeably calmer than July's. Add a morning start and you'll often have your stretch of water nearly to yourself.

The honest stuff: heat, algae, and pop-up storms
We'd rather you plan around reality than be surprised, so here's the full picture — none of it is a dealbreaker:
- The heat is real in the afternoon. Mid-afternoon in August can hit 100°+. The fix is simple: go in the morning, bring more water than you think you need, and reapply sunscreen every couple of hours. Falling into 88° water every few minutes helps more than you'd expect.
- Algae advisories happen, rarely and locally. In late summer, officials occasionally flag specific coves for algae blooms. We keep an eye on advisories, ride in open water, and steer clear of anything scummy near shorelines. With ten lakes to choose from, there's always clean water to surf.
- Afternoon storms pop up, then leave. August thunderstorms in North Texas are usually short, late-day events — one more point for the morning session. If weather genuinely wrecks your slot, we'll work with you to reschedule.
What an August session costs
Same transparent pricing as all season: a captained boat is $275/hour (up to 12 guests) with free coaching for the whole crew — you just show up in a swimsuit. Self-drive is $225/hour (up to 10 guests, experienced surf-boat drivers). Want a focused first lesson? Lessons are $275/hour (up to 8 people, two-hour minimum). Boards, tube, and life jackets are all included; gas is billed separately at cost. Full breakdown here: what it costs to rent a wake boat in DFW.
Picking your lake for a summer morning
We deliver the boat to the marina on whichever of our ten North Texas lakes you pick — Possum Kingdom, Lewisville, Grapevine, Texoma, Ray Roberts, Ray Hubbard, Cedar Creek, Tawakoni, Eagle Mountain, or Granbury. For a hot August day, deep clear water (Possum Kingdom) or a quick drive from Dallas (Grapevine, Lewisville) are both great calls. Not sure? See the best lakes to wakesurf near Dallas or just ask — we're on these lakes every week.
Frequently asked questions
Is the lake water too hot to wakesurf in August?
No — there's no such thing as too warm for wakesurfing. Upper-80s water just means falling in is pleasant and nobody needs a wetsuit. The afternoon air is the thing to plan around, and a morning session solves it.
What should I bring for an August session?
Swimsuit, towel, more water than you think you need, snacks, and reef-friendly sunscreen (reapply often). A hat and a light sun shirt are smart for between sets. Boards, tube, and life jackets are already on the boat.
Is August less crowded than July?
Noticeably. Once the July 4th wave passes, weekends calm down and weekday mornings can feel like a private lake. It's one of the easiest times of the season to grab a great slot.
Can kids come along in August?
Absolutely — warm water is the most kid-friendly water. Keep them hydrated and shaded between turns, and see our tips for wakesurfing with kids.
What if a storm rolls in during my slot?
August storms are usually brief and late-day. If weather genuinely shuts down your session, we'll work with you on a reschedule — nobody surfs in lightning.
