Traveller notes on San Juan del Sur in January
Notes from nearby Granada (76 km away)
San Juan del Sur doesn't have its own notes for January yet — these are about Granada, close enough to share the season.
Forum posters describe January nights typically in the low-to-mid-70sF, warming to the upper-80s to low-90sF by day - genuinely hot, with Granada named by posters as one of the hottest cities in the country on average. Posters consistently call this the dry season here: the surrounding landscape turns brown and dusty, a sharp contrast to the lush green of the wetter months. Posters recommend the November-January stretch as the best overall window for a first visit to Granada and Nicaragua generally, though they note conditions keep warming through January itself - by the back half of the month, several posters mention needing a fan overnight as nights stop cooling off as much as earlier in the month.
Other months in San Juan del Sur
San Juan del Sur's forum describes September and October as the heaviest rain of the year here, but the typical day still follows a manageable rhythm: cooler and overcast at dawn, clouds burning off by mid-morning, then sunny through the afternoon before rain returns. Posters said showers roll in roughly every other day and usually last only an hour or two rather than the whole day. A few forum regulars specifically preferred August over September, since the risk of a genuinely wet stretch climbs the closer you get to the end of the month.
Forum posters describe March as squarely inside the strong seasonal wind window that runs January through March, with the ocean itself running noticeably cooler (around 17C) during the windiest stretch and beach days sometimes getting genuinely uncomfortable - one reviewer described wind strong enough to feel like it was 'beating' them while trying to lie on the beach. By March the pattern shifts toward hot, dry and dusty conditions on land even as the wind persists, with posters generally naming April (before or right after Easter week) or very early May as calmer, more comfortable alternatives for travelers who prioritize a still, sunny beach day over surf conditions - Papagayo-style offshore winds like this one are prized by kitesurfers even as they frustrate sunbathers.
