Traveller notes on San Andrés in December
Other months in San Andrés
San Andrés's forum calls April hot and sunny, though high season with more tourists and higher prices than the quieter shoulder months. Regulars are consistent that the typical pattern is sunny mornings turning to cloud or rain in the afternoon, and flag the island's weather as genuinely hard to forecast given its exposure to El Niño/La Niña swings — March is often cited as the calmer, cheaper alternative with similarly good weather.
