La Réunion weather: sunny start, grey afternoon ahead

For residents of La Réunion, the day of 12 November 2026 begins with generous sunshine, but the forecast from Météo-France La Réunion makes clear that the pleasant morning will not last. Before midday, clouds start to build along the slopes of the island’s interior. By early afternoon, the grey cover thickens and spreads. For anyone planning errands, commutes or time outdoors, the day’s rhythm matters: showers develop over the higher ground and then move down toward the coast.

“Un peu comme la veille, des averses se produisent alors sur le relief, avant de déborder et rejoindre le littoral entre St-Leu et La Grande-Chaloupe,” the forecaster notes, meaning the showers spill from the relief onto a stretch of the shoreline between Saint-Leu and La Grande-Chaloupe. Not everything goes grey at once, however. Clear spells hold on along the eastern coastal fringe, from Sainte-Rose to Champ-Borne, for a good part of the day.

The wind setup behind this picture is relatively mild. A general flow from the east-southeast remains fairly weak, and gusts of trade winds, reaching at most 40 to 50 km/h, circulate along the northern shores and the south-southeast. Over the interior and the west of the island, a regime of breezes dominates instead, a calmer pattern that shapes conditions for anyone working or travelling inland.

For daily planning, temperatures give the clearest signal. Maximum values reach between 27 and 30 degrees Celsius along the seaside, while the cirques, the island’s enclosed mountain basins where many residents live and work, stay cooler at up to 24 degrees Celsius. The contrast between warm coasts and milder uplands is a familiar feature of the island’s weather. On a day when clouds and showers move in from early afternoon, it helps explain why conditions can vary sharply over short distances.

Meanwhile, the state of the sea rounds out the picture, and it matters for fishermen, boaters and anyone heading to the shore. The sea is agitated overall, though only slightly agitated along the north. A southerly swell of around one metre fifty continues to ease, a gradual weakening that suggests slowly improving conditions along exposed coasts even as the sky darkens inland.

Taken together, the forecast describes a day in two halves for the island’s inhabitants: a bright, usable morning followed by an afternoon when cloud and showers spread from the heights down to parts of the littoral. The eastern coastal strip keeps its breaks of light for most of the day, a small consolation for those on that side of the island. As Météo-France La Réunion summarises, the morning sun is generous, the clouds arrive before midday, and by the afternoon the grey has the upper hand, with the showers reaching from the relief to the coast between Saint-Leu and La Grande-Chaloupe while Sainte-Rose to Champ-Borne holds onto its clear spells.

For a population whose daily routines, from school runs to work travel, depend on knowing when the weather will turn, this trajectory from sunshine to grey is the essential takeaway of the day. Text for the forecast comes from Météo-France La Réunion and F.F, and the piece is signed by Fabrice Floch. Whether the easing swell and lingering clear spells in the east will hold into the following day is what islanders will be watching next.
