1. March 2026 Weather & Water Conditions
March is historically one of the hottest and driest months on the Pacific Coast. According to data from the National Meteorological Institute (IMN), reliable patterns for this month include:
- Air Temperature: Average highs between 89°F and 91°F (32°C - 33°C).
- Water Temperature: A consistent, bait-attracting 84°F.
- Wind Speed: Low, averaging around 3 mph, ensuring "lake-like" conditions offshore.
Pro Tip: While March is dry, late-afternoon showers can occur as we inch closer to April. We recommend full-day charters starting at 7:00 AM to maximize the prime sun hours.
2. What's Biting: The "Verano" Peak
Exceptional fishing weather translates to exceptional activity below the surface. March is defined by density—the sheer volume of baitfish brings the predators close.
Offshore: The Billfish Bonanza
This month is the traditional peak for the "Grand Slam" contenders. The Offshore World Championship is held nearby for a reason—the numbers here are unrivaled.
- Pacific Sailfish: Expect double-digit releases on good days.
- Blue & Black Marlin: Aggressive and feeding near the surface.
- Yellowfin Tuna: Found traveling with spinner dolphins.
- Mahi-Mahi (Dorado): Excellent table fare and abundant.
Inshore: The Shallow Water Fight
For those who prefer the dramatic coastline views of Jaco and Herradura Bay, inshore fishing offers heavy-hitting action:
- Roosterfish: The trophy fish of the inshore, identified by their iconic seven-spine dorsal fin.
- Cubera Snapper: Strong bottom dwellers that test your tackle.
- Tarpon: Occasional giants weighing upwards of 200 lbs in specific currents.
