Faja da Caldeira de Santo Cristo - surf spot statistics

Faja da Caldeira de Santo Cristo in Portugal is a wave-rich spot with consistent swell year-round, but the best conditions for surfing are typically found during the autumn and winter months. From October to March, the swell is dominated by powerful ground swells, with the highest percentages (63-78%) and larger mean swell sizes (1.9-2.4m). December stands out as particularly strong, offering the biggest waves (2.4m) and a high likelihood of ground swell (74%). However, wind conditions during this period are often unfavorable, with bad winds occurring 82-88% of the time, which can make sessions tricky unless offshore winds align. Spring (April-May) and early autumn (September) provide a balance between decent ground swell (42-63%) and slightly better wind conditions, though still with a majority of onshore winds. The worst time for quality waves is summer (June-August), when wind swells dominate (65-71%), swell size drops significantly (1.0-1.2m), and conditions are often mushy. While summer has the highest chances of favorable winds (27-36%), the small, inconsistent swell makes it less ideal for advanced surfers. For the best combination of solid waves and slightly improved wind odds, late September to November can be a good window, avoiding the peak winter wind issues while still benefiting from a strong, clean swell.

November at Faja da Caldeira de Santo Cristo offers solid surf conditions with an average swell height of 2.2m and a consistent period of 11.4s, indicating powerful, well-spaced waves. The dominant swell directions are from the northwest and north-northwest, contributing the majority of the larger waves (1.5m+), which account for a significant portion of the swell distribution. These swells produce quality, powerful surf, especially when combined with the spot’s exposure to open ocean energy. Wind conditions are a mixed bag—only 15% of the time is the wind ideal for surfing, primarily when it’s light (under 20kph) and offshore or sideshore. The most troublesome winds come from the southwest and west, which can create choppy or blown-out conditions, especially at higher speeds (20-30kph+). Overall, November delivers strong, consistent waves, but patience is needed to score the best sessions when winds align.
