Your best friend in the Panamanian winter months (May to December) may be your umbrella! Downpours – or aguaceros as they are called here – can overtake a blue sky in seconds! The thunderous rain comes down as though buckets of water were falling on your head, and the speed at which you can dig into your pocket and extract your umbrella may determine whether or not you look like you’ve jumped in the Bay fully clothed (which I don’t recommend – the water is quite contaminated)! The rain can even be a bit too much for an umbrella. My recommendation is to hop in one of Casco Viejo’s lovely cafés, sit the storm out (the heavy rain usually does not last for more than an hour) and comfort yourself with the knowledge that you really are having a truly Panamanian experience.
