Earlier this spring, I posted an article about seasonal climate forecasting and noted that we expected to see the development of an El Niño after three years of La Niña conditions ended in March 2023. And sure enough, an El Niño was declared in August 2023 and has been strengthening ever since. It has a 71% chance of becoming a strong event by December or January before starting to weaken, as they usually do in spring or early summer.… Continue reading this article “What a strong El Niño means for winter weather and our gardens”

How did your garden fare this year? No matter how it grew, at least some of the impact was due to this year’s weather, although careful soil preparation and a good watering plan can fend off some of the worst effects. As usual, my last blog post of the year will be a brief review of this year’s climate and a look ahead to next year. Gardeners must prepare as well as dream! My review will focus heavily on the United States, but I will try to put in a little for our non-US readers too.… Continue reading this article “Goodbye to another weather year–2025 in review”

In the last few weeks NOAA has declared the end of the weak La Niña that has been present in the eastern Pacific Ocean and the return to neutral conditions. I want to take time today to discuss what it means for our summer growing season in the United States. I will also provide some links to guidance for how it might affect conditions in other parts of the world for our non-US readers.

Why do we keep track of La Niña and El Niño?

How did your garden grow in 2024? Was it a lush playground full of beautiful flowers and plentiful produce? Or was it a sere landscape of brown, wilted foliage? How your own garden fared in 2024 was certainly dependent on where you live, what you had planted, and how you took care of it, but it was also subject to the variations in weather and climate in your area. This week we will take a look back at the climate conditions in 2024 and look forward to what it might mean for 2025.… Continue reading this article “2024 in Review and a look ahead to 2025”

As I write this, about half of the lower 48 United States has passed the median date of the last freeze according to the National Centers for Environmental Information. Here in the Southeast, we are well into the planting season even though our usually early planting for crops like corn was delayed due to very wet soil. The rest of you may have to wait for a few more weeks before you can put any heat-loving plants into the ground.… Continue reading this article “What we expect in the 2024 growing season”

In this blog I’ve talked several times about El Niño and La Niña and how they affect climate across the Northern Hemisphere as well as their impacts on the rest of the world. We are currently in a strong El Niño with sea surface temperatures in the Eastern Pacific Ocean (EPO) that are much warmer than the long-term average. But underneath the surface the ocean currents are starting to change and the El Niño is expected to swing quickly into the opposite phase, La Niña.… Continue reading this article “The Times They Are A-Changin’—What the new La Niña Watch means for the NH growing season”

This year is almost certain to be the warmest on record for the earth as a whole, although there are still a few days in December that could slightly affect the final numbers. As we close out 2023 I want to spend a few minutes reviewing the weather and climate of the past year, both the average conditions and some of the extremes we saw. While this is skewed towards the United States, I did include some events happening in other parts of the world for our non-US readers.… Continue reading this article “The warmest year on record ends–will 2024 be hotter?”

This time of year, I often get asked for a forecast for the coming growing season. Will we have a drought? Will it be warmer or colder than normal? Will we have any tropical storms in our area? All of these things affect how farm crops (and gardens) will perform over the next few months and how big the yield might be when it comes time to harvest. In this week’s blog, I will look at some of the factors that go into seasonal forecasting and how it all comes down to numbers.… Continue reading this article “Seasonal forecasting: Looking into the crystal ball”

Last April 30, 2022, I wrote a post about what a third year of La Niña meant for gardens. La Niña, you might remember, is an atmosphere/ocean phenomenon driven by unusually cold water in the Eastern Pacific Ocean (EPO) that shifts the jet streams that steer storm systems around the world. In La Niña winters in North America, it is often linked statistically to colder and wetter than normal conditions in northern parts of the United States and north into Canada and warmer and drier conditions in the southern tier of states in the US.… Continue reading this article “Hasta la vista, La Niña!”
