The 2024 hurricane season is unique because we’re transitioning from El Nino to La Nina climate patterns. Understanding this phenomenon and the effects on the Atlantic basin – which includes the Atlantic Ocean, Gulf of Mexico, and Caribbean Sea – can help Florida homeowners prepare for the potential dangers of hurricanes and tropical storms.
Let's find out more about El Nino and La Nina, including how they’re expected to influence hurricane formation in the waters surrounding Florida. In addition, it’s important to note both are occurring in a warming world, which exponentially increases their potential impacts.
Understanding El Nino and La Nina
El Nino and La Nina are climate patterns originating in the Pacific Ocean but with far-reaching effects on weather across the globe. They are opposite phases of the ENSO cycle, which influences weather patterns worldwide.
El Nino and La Nina tend to appear every handful of years, on an irregular schedule – for example, El Nino tends to occur more frequently than La Nina. Once either pattern is present, it can last for one to multiple years. When neither is present, the atmospheric conditions are known as ENSO-neutral.
El Nino
El Nino years tend to bring fewer hurricanes to the Atlantic basin. The increased upper-level wind shear associated with El Nino can disrupt the formation and intensification of hurricanes.
- Reduced hurricane activity: The Atlantic, Gulf of Mexico, and Caribbean Sea experience fewer tropical storms and hurricanes.
- Weaker storms: When hurricanes do form, they are often less intense due to disrupted development.
- Greater stability: Overall atmospheric stability increases, reducing the likelihood of hurricane formation.
During an El Nino year, Florida homeowners might experience a relatively calm hurricane season. However, it is crucial to remain vigilant as even a single hurricane or tropical storm can cause significant damage.
Outside of its effects on the Atlantic hurricane season, El Nino typically contributes toward higher temperatures felt around the globe, including warmer ocean temps. During El Nino, the Pacific jet stream – a fast-moving current of air moving from west to east – is pushed to the southeast, bringing wet weather to the Southern U.S. and dry, warm weather to the Northern U.S. over the winter months.
La Nina
In contrast, La Nina years are associated with increased hurricane activity in the Atlantic basin. Reduced upper-level wind shear creates more favorable conditions for hurricane development and intensification.
- Increased hurricane activity: The Atlantic, Gulf of Mexico, and Caribbean Sea experience a higher number of tropical storms and hurricanes.
- Stronger storms: Hurricanes are often more intense, with a greater likelihood of reaching major hurricane status.
- Enhanced development conditions: The atmosphere becomes more conducive to hurricane formation and growth.
With La Nina conditions, Florida homeowners should be especially alert and prepared for a potentially active and dangerous hurricane season.
Generally speaking, La Nina is associated with lower global temperatures. It pushes the Pacific jet stream northward, contributing to dry, warm weather in the Southern U.S. and colder, wetter weather in the North over the winter.
Transitioning from El Nino to La Nina
The transition from El Nino to La Nina this summer can lead to a dynamic and unpredictable hurricane season in 2024. Here's what you can expect:
Early Hurricane Season
El Nino faded away, for the most part, by the start of the Atlantic hurricane season on June 1, 2024. The early part of the hurricane season may still exhibit characteristics typical of an El Nino year, such as reduced hurricane activity and weaker storms. However, as La Nina conditions begin to appear, this transition will gradually alter atmospheric conditions, setting the stage for a more active latter half of the season.
- Gradual increase in activity: Hurricane activity may start lower but increase as La Nina conditions take hold.
- Potential for surprise storms: While early-season activity might be reduced, isolated storms can still form and pose a threat.
Peak Hurricane Season
The peak of the hurricane season, typically from August to October, is likely to reflect the full influence of La Nina conditions. This period could see heightened hurricane activity, with an increased number of storms and stronger hurricanes.
- Heightened vigilance: Homeowners should be particularly alert during this peak period.
- Preparation is key: Ensure your home and family are ready for potential storms and have a plan in place.
Preparing for the 2024 Hurricane Season
Understanding the transition from El Nino to La Nina is crucial for effective preparation. What follows are some practical steps Florida homeowners can take to stay safe and minimize risks during the 2024 hurricane season.

Stay Informed
Keep abreast of weather forecasts and updates from reliable sources like the National Hurricane Center and local meteorologists. Being aware of potential storm developments allows you to take timely action.
- Regularly check weather reports and updates.
- Utilize weather apps and alerts to stay informed on the go.
Strengthen Your Home
Ensure your home is well-prepared to withstand the impact of hurricanes, no matter if El Nino or La Nina is in effect. Simple improvements can make a significant difference in protecting your property.
- Install storm shutters or reinforce existing ones.
- Ensure your roof is in good condition and consider adding hurricane straps for extra reinforcement.
- Remove any loose items from your yard; anything picked up in the wind could become a dangerous projectile.
Update Your Emergency Plan
Each year, you should review your disaster plan – making updates where needed – to help you, along with everyone in your household, know exactly what to do during a hurricane.
- Know your evacuation routes and have a destination planned.
- Assemble an emergency kit with essentials like water, non-perishable food, medications, and important documents.
- Establish a way to stay in touch with family and friends.
Review Your Insurance
Review your homeowner's insurance policy to ensure you have adequate coverage for potential hurricane damage. Understanding your policy can prevent financial stress in the aftermath of a storm.
- Ensure your coverage limits will cover the full value of your home and belongings.
- Know how much you'll need to pay out of pocket (your deductibles) if you need to file a claim.
- Evaluate the need for flood insurance, which is typically not included in standard homeowner's policies.
It’s important to review your current homeowners insurance coverage with your insurance agent sooner rather than later – because no policy changes can be made once a watch or warning have been issued for a named storm. In addition, flood insurance often comes with a 30-day waiting period before any new policy goes into effect.
Be Ready This Hurricane Season, With Increased Vigilance & Preparation
While the science behind El Nino and La Nina may seem complex, the key takeaway for Florida homeowners is understanding how these long-term climate patterns affect the Atlantic hurricane season. The transition from El Nino to La Nina in 2024 means increased vigilance and preparedness are essential.
By staying informed, strengthening your home, creating an emergency plan, and reviewing your insurance, you can navigate the 2024 hurricane season with greater confidence. Remember: Even though the prospect of being hit by a hurricane is daunting, proactive preparation can significantly reduce risks and ensure you and your family stay safe.
