Today brought a small but very welcome change to the skies over Town. After many particularly dry days, the morning began under cloudier skies and with noticeably more humidity in the air. Then, during the afternoon, we finally had something we had not enjoyed in quite some time: a short shower of rain.
According to Costa Rica’s National Meteorological Institute (IMN), the Intertropical Convergence Zone is currently positioned close to the country, contributing to greater atmospheric instability and increased humidity, particularly along coastal areas. Early in the day, this translated into warmer, more humid conditions, while later in the afternoon it helped bring the brief rainfall we experienced in Town.
And even if it did not last very long, it was certainly good news as the effects of El Niño have been particularly noticeable this year, with much drier conditions than we would normally expect during months that are typically among the rainier ones along Costa Rica’s Pacific coast. With the Intertropical Convergence Zone nearby, there is a possibility of additional showers over the coming days, including some afternoon thunderstorms.
Beyond bringing a cozy change in weather, rainfall plays an important role in restoring the landscape after long periods of dryness. As water reaches the ground, some of it infiltrates the soil, replenishing the moisture available to plants and their roots. When rainfall is sufficient, part of that water can continue filtering through deeper layers of soil and rock, eventually contributing to the recharge of groundwater and aquifers.
It is a gradual process, and one that happens almost entirely out of sight. A single short shower may mostly help restore moisture closer to the surface, while more sustained rainfall over time allows water to continue moving deeper underground.
And perhaps that is one of the loveliest things about welcoming the rain back, or hopefully, doing so. Long before we notice greener hillsides, fuller vegetation, or new growth along the trails, something is already changing beneath our feet. The soil begins to regain moisture, roots find water again, and, little by little, the landscape starts replenishing what the dry months have taken away.
So today, we are happily welcoming the cloudy skies, the possibility of a little thunder, and hopefully a few more rainy afternoons ahead. After so much sun and dryness, even a brief shower can make Town feel completely different, while quietly beginning to give something back to the landscape that surrounds us.
