Summer Spearfishing: What to Watch Out for in July and August!

Summer Spearfishing: What to Watch Out for in July and August!

A Complete Guide to Safe, Productive, and Enjoyable Summer Spearfishing Adventures

The summer season is a unique and challenging period for spearfishing enthusiasts. While the clear waters and longer daylight hours may seem ideal, July and August bring particular difficulties that every spearo should consider. These stem mainly from two major seasonal phenomena that are deeply interconnected: increased human activity in coastal areas and elevated sea temperatures.

Why Summer Spearfishing Requires Extra Caution

When the weather heats up, the ocean doesn't just warm — it transforms. Marine ecosystems shift, fish behavior changes, and coastal zones fill up with thousands of vacationers. While spearfishing in the summer offers stunning visibility and the potential for rewarding dives, it also brings specific risks and obstacles that you must navigate wisely.

Below, you’ll find an in-depth breakdown of the main challenges of summer spearfishing and how to overcome them, including practical tips, gear recommendations, and best practices to keep you safe and successful underwater.

1. The Human Factor: Navigating Crowded Waters

During the peak summer months, beaches and coastal zones become packed with vacationers. From swimmers and snorkelers to jet skis and tour boats, the sea becomes a busy, noisy, and often chaotic environment. As spearos, we are used to solitude and quiet underwater hunting grounds—but in July and August, that changes dramatically.

What to Expect:

• Increased surface traffic
• Loud noise pollution
• Disrupted fish behavior
• Reduced visibility near the surface

What to Do:

• Avoid popular beaches and choose secluded, rocky, or less accessible locations.
• Use a high-visibility buoy with a dive flag to alert boaters of your presence.
• Never surface abruptly—always check above you before ascending.

2. Rising Water Temperatures and Fish Migration

Warmer waters in the upper layers push many fish species into deeper, cooler zones. In addition, increased human activity deters fish from shallow spots they’d normally frequent during other seasons.

How This Affects You:

• Fewer fish in traditional shallow spots
• Deeper dives required
• More energy spent searching for prey

Solution:

• Focus on transition zones (steep drop-offs, reef edges, etc.)
• Study seasonal patterns of your target species
• Use sonar (if available) to locate fish-holding depths

Pro Tip: Morning hours often offer the most fish activity near shallows due to cooler temperatures and reduced noise.

3. Best Time of Day to Dive: Early Morning or Late Afternoon

If you have access to a boat, try to be in the water as early as possible—ideally around sunrise. Most vacationers tend to stay out late at night and sleep in, so early mornings are quieter and offer better chances for productive hunting. Late afternoons can also be productive, with less surface noise and fish returning to feed.

Why Early or Late Is Best:

• Reduced surface traffic
• Cooler temperatures
• Higher fish activity near shore

Safety Tips:

• Check weather forecasts and currents before your trip
• Dive with a buddy whenever possible

4. Midday Sun = Maximum Risk

High temperatures and UV radiation around noon can be punishing. Prolonged exposure leads to dehydration, fatigue, and sunstroke. Combine this with physical effort in the water and the risks multiply.

Precautions:

• Avoid diving during the hottest hours (11 am–3 pm)
• Wear UV-blocking rash guards or wetsuits
• Use sunscreen on exposed areas (neck, face, hands)
• Rehydrate regularly

5. Shore Entry Tips for Spearfishers Without a Boat

If you don’t have a boat, plan your dives either early in the morning or late in the afternoon. Fish often return to the shallows during these periods, and the lighting conditions are less intense.

Important Reminders:

• Avoid venturing too far from shore
• Be cautious of boats and jet skis
• Always carry a buoy with a dive flag

Advanced Tip: Scout your entry and exit points ahead of time and choose rocky coasts with limited tourist activity.

6. Hunting in Windy or Choppy Waters Can Be Productive

Wind-exposed (windward) shores are usually more productive than calm (leeward) ones. The waves stir the water, attracting species that feed on stirred-up nutrients and organisms.

Advantages:

• More active prey species
• Less human presence
• Murky water provides better cover for stalking fish

But... Stay Safe:

• Monitor currents and exit points
• Avoid solo diving in rough conditions

7. The Importance of Steep Drop-offs and Reef Edges

Places where the seafloor drops off quickly tend to hold more and bigger fish. These spots offer quick access to deeper refuges, making fish feel safer.

Tactics:

• Use ambush techniques (agguato) near reef ledges
• Approach slowly and use natural cover
• Pay attention to thermoclines and water temperature shifts

8. Hydration and Nutrition for Endurance

Summer heat combined with physical exertion leads to fast dehydration. Drink water before, during, and after your dive. Electrolyte drinks are a bonus on long sessions.

Extra Tips:

• Use an insulated bottle in your buoy to carry cold water
• Snack on energy-rich and water-dense foods (watermelon, bananas, nuts)

9. Sun Protection Above and Below the Surface

Wearing a large hat and lightweight, breathable clothing helps protect you from harmful UV rays. Heatstroke is a serious risk.

Quick Checklist:

• Wide-brimmed hat
• Long-sleeve UV shirt
• Polarized sunglasses
• Light pants or shorts

Bonus: A reflective tarp or umbrella on the boat can help reduce sun exposure during breaks.

10. Say No to Alcohol Before a Dive

Alcohol causes dehydration and impairs judgment. Even a small drink the night before can affect your dive safety. Spearfishing demands full mental clarity, especially in summer.

Best Practice:

• Skip alcohol 24 hours before a dive
• If celebrating after, rehydrate thoroughly first

11. Optimize Your Speargun Setup for Summer Conditions

You don’t need a massive setup—just one that’s balanced, well-tuned, and adaptable. A versatile speargun (95–105 cm with twin 16mm bands and a 6.75–7 mm shaft) covers most summer conditions.

Smart Loadout:

• Primary gun: Medium-length railgun with reel
• Backup: Smaller gun or polespear for caves/shallow work
• Sharpen your spear tips before each session

12. Mental Clarity and Relaxed Dives = Safer Results

Spearfishing should be enjoyable, not stressful. Don’t push your limits to reach a favorite rock or spot. Relax, observe, and adjust based on conditions.

Mindset Checklist:

• Don't compare your dives to others
• Set realistic expectations
• Embrace each dive as a learning opportunity

Final Words

Summer spearfishing requires adaptability, awareness, and respect for the sea. Prioritize your safety, protect marine life, and enjoy every dive mindfully. Whether you’re exploring a hidden reef or diving with friends on a sunlit morning, remember: the sea always rewards those who approach it with humility and preparation.

Stay safe, dive smart, and maybe we'll cross paths underwater someday!
