Transition to the Wet Season: Staring the Wicked Witch in the Face Again

In late-September and early-October we are in the transition to the wet season. We have had a nice “mid-year summer” and sure won’t complain. Between now and December we are looking at increasing amounts of rain and a lot of cool, cloudy weather. The reappearance of la niña (the wicked witch) and its expected residence through the upcoming rains indicates they are likely to be heavier than “normal.” But then again what is normal after nearly 3 la niña episodes in a row. BTW the wicked witch brings excessive rains to Colombia and is not a welcomed guest in most quarters.


Guayacan Amarillo

As the dry season gets underway here in Medellin the yellow guayacans (Tabebuia chysantha) are blooming up a storm. These are the trees that look like clouds of brilliant yellow all over the city.

The Wicked Witch is Dead?

IDEAM is the Colombian equivalent of the National Weather Service in the US with additional responsibilities.  They are calling the end of this la niña event for the country. This is welcome news as the flooding and landslides during the fall/winter and spring wet seasons have been catastrophic. Now we are waiting for the passage of the normal seasonal rains to finish and take the water on up toward Central America. Here in Medellin we have our fingers crossed and are hoping that the last 15 days or so of the first rainy season are not to wet.  We did have some really nice weather over the past month with plenty of sunny, dry days.

The Rains Have Begun

24 April 2010

This past week has been very warm and dry again. Most of the climate modeling suggests that the el Niño condition will end during the Northern Hemisphere summer and NOAA seems to be pretty sure about that now. I for one will be pleased to see the normal rains again.

The rainy season has started in earnest now. This past week has been very wet with rain most days. Several afternoons and evenings brought heavy downpours. The humidity is up a lot. This past dry season was intense and lasted longer than normal. Generally in mid-March there is a distinct increase in rainy weather. This year we had a couple of wet days but no where near enough.

NOAA has indicated that the el Niño should last only through this northern hemisphere summer. That would put us on track for a normal rainy season between October and December.

I just added a page on the climate here which you can find at this link or in the list of pages to the left of your screen.

Rainy Season On Its Way?

The last few days have been quite humid and we have had a few showers. I see on the satellite imagery that the rains are moving into the southern departments of Colombia. It is beginning to look like we may start to get some significant rain in a few weeks, el Niño and all. I have my fingers crossed.

25/02/10: More rain yesterday afternoon making the evening cool and pleasant. The patio is still damp so it may have rained duirng the night. Very welcome!

Rainy Season and Water Supply

Well it looks like the rains have now begun in earnest. We were expecting the season to start in September but that did not happen. That month was very dry and quite hot. This last week however has been rather wet and with any luck this will continue.

El Nino generally brings dry weather to large parts of the Colombia and this time is no different. It is anticipated that the southwestern portion of the country is likely to have water rationing in February. The September drought caused some problems for farmers up in the Santa Elena area and a lot of folks there were getting worried. Our well was getting very low and we had some touch and go days.

We should be getting hooked up to the municipal water system within the next few months. This will be good assuming the system was designed to handle drought years. I’m considering installing a reserve tank to handle any system problems that may occur.

A city water connection will definitely be an advantage health wise. Ours is a shallow well and while we have not had any significant problems yet such wells represent a risk factor. Fortunately there are no homes upstream of the take but this does not rule out animals as vectors. We have been using the hot water tank as a pasteurizer. This has worked well but at times a cold glass of water rather than tea or coffee would be welcome.

Rainy Season


Here we are in mid-September and it looks like the rainy season is getting started. We had nice gentle rains the last two nights and right now we are having a good soaker. I’m glad to see it arrive! We will have to get some leaks in the roof fixed but the rains make Colombia a very green country.


The rains continued on and off throughout the day. Nice soaking rains that we have not seen since May. Talking with a cabbie on the way home we shared our appreciation for the liquid gold. He is from a country background. He understands that the rain is our wealth. We don’t eat without it.

In the mid-afternoon I went for a short walk. Everything was damp and smelled very fresh. It was cool and humid. Easy on the nose and skin. All the plants were the fresh green they attain only just after a good rain. Peace and abundance. Gentle fertility. May you be filled with loving kindness, may you be well.

Rainy Season

Well we are on the cusp between the mid-year dry and fall rainy seasons. The fall rains generally increase slowly after mid-September and are in full swing in October and November. By mid-December they have pretty much stopped and the early dry season begins. The term “dry season” is relative as we do get some rain during these periods.

IDEAM, the national weather bureau is expecting slightly lower than average rains over much of the country due to the developing El Niño conditions. This would be welcome around here as last years La Niña brought excessive rain with lots of flooding.

Right now we have a good thunder bumper cranking up. These are very common between about 1500 and 1700.

Dry Weather

This dry season is turning out to be toasty. The lawns are starting to show stress and we had several brush fires in different areas around the city over the weekend. A few of the shrubs in landscapes around town also are showing stress. So far I don’t see any difference in the trees. When I got back to the house yesterday several of the container plants had dried out which is uncommon.

In addition we had strong winds over the weekend. This is the fist time I have seen strong regional winds. I is likely that we are seeing the effects of El Niño setting in.  While this is normally a fairly dry part of the year it seems to be drier and warmer than normal.
