Traveller notes on Peniche in September
Notes from nearby Nazaré (38 km away)
Peniche doesn't have its own notes for September yet — these are about Nazaré, close enough to share the season.
September in Nazare is pleasant and the wrong month for what the town is famous for. Regulars put the giant waves between October and February, with December to February the reliable window and January capable of 30 metres and more; September gives you no great chance of them. What it does give is warm, mostly sunny weather at 19 to 22C - our row says 24.6C over 16C - with the beach itself cool enough that some visitors complain. The Atlantic here stays at 19.3C. So: come now for the town and the cliff at O Sitio, come in winter for the spectacle. The record: 4.6 precipitation days carrying 32.1mm, a 20.7 kph wind and 10.7 hours of sun.
Other months in Peniche
There isn't much Peniche-specific forum detail for January, but Portugal's broader threads sketch the range this stretch of coast falls into: wetter and greyer up north around Porto, milder and sunnier down in the Algarve, with daytime temperatures nationally landing somewhere in the mid-teens C and evenings turning chilly fast once the sun sets around 5:30pm. Peniche's own numbers put it toward the milder, drier end of that spread - still a proper Atlantic winter, but not the grey, near-constant rain some posters describe further north. The town's famous coastal wind is worth packing for regardless of the rain forecast.
Forum posters describe July surf conditions as ideal for beginners - generally small, manageable waves and pleasant water temperatures, with Baleal (a small town just outside Peniche) named as the real center of the area's surf scene, where the large majority of surf lessons and sessions actually happen. Posters are consistent July is genuinely one of the busiest, most touristy months on this stretch of coast, with beaches getting packed and accommodation booking up well in advance - a pattern posters say holds across the whole Peniche-Ericeira-west-Algarve surf coast, not just Peniche itself. On temperature, posters describe comfortable, warm summer days overall, with occasional hotter spikes rather than sustained extreme heat.
