If you ask local pilots which three months they'd choose to fly in Portugal if they could only pick one season, spring usually wins. March, April, and May offer a specific meteorological sweet spot: mild temperatures, calm mornings before the afternoon sea breeze builds, and the year's first genuine thermal activity arriving without the intensity that makes high summer occasionally overdeveloped. This guide explains exactly why, month by month.
Why Spring Is the Meteorological Sweet Spot
Winter's Atlantic frontal systems become less frequent through March, while the full-strength summer nortada hasn't yet established its grip on the coast. The result is a transitional window where coastal soaring stays reliable, thermal activity starts building gradually rather than exploding into the sometimes-turbulent intensity of July and August, and the air itself is smoother — pilots regularly describe spring flying as "calm enough to feel suitable for newer pilots, dynamic enough to stay interesting for experienced ones."
Month by Month
March — the first thermal days
March brings the first genuine thermal days of the year, alongside dependable coastal soaring and — on the days the wind shifts northerly — some genuinely strong ridge conditions. Crowds are minimal; this is shoulder season by any tourism measure, and the launches reflect that.
April — the consensus favourite
Ask any pilot who flies Portugal regularly and April comes up more than any other month. It delivers a genuine mix: some days are pure coastal soaring days, others produce proper thermal activity inland, and the alternation between the two within a single week gives visiting pilots the best overview of what Portuguese flying actually offers. Crowds remain moderate.
May — XC season opens
By May, the XC season is properly underway. Thermals extend their reach into Alentejo, cloudbase regularly reaches 1,200–1,800 metres on good days, and pilots chasing their first serious cross-country distances of the year find May consistently productive.
What Beginners Experience in Spring
Spring air is consistently described by instructors as calm and smooth — genuinely suitable for pilots early in their progression. The combination of reliable coastal soaring with gentle, building thermal activity (rather than summer's sometimes punchy midday convection) makes spring an excellent window for a first coaching week, ground-handling intensives, or simply building confidence at a measured pace.
What XC Pilots Experience
For pilots who soared through winter and are eager to get back into proper cross-country flying, spring — particularly late April into May — delivers the first genuinely productive XC days of the year. The thermals are strong enough to produce real distance without yet carrying the overdevelopment risk that creeps in during peak summer heat.
Morning vs Afternoon Pattern
Spring mornings in Portugal are frequently too calm to fly — the day's lift hasn't built yet. The reliable pattern is a light morning, a developing midday, and a genuinely good afternoon window as the sea breeze and inland heating both kick in. Visiting pilots should plan their daily schedule around this pattern rather than expecting dawn-patrol flying.
How to Book for Spring
April and May fill up faster than the shoulder months either side, simply because word has spread about how good the conditions are. Pilots planning a spring week should reach out in January or February to lock in dates — though given the "plan close" model, the exact days within your chosen week are still confirmed closer to arrival based on the actual forecast.
Spring vs Autumn — An Honest Comparison
| Factor | Spring | Autumn |
|---|---|---|
| Wind strength | Slightly windier on average | Generally calmer, more settled |
| Thermal character | Building, increasingly strong toward May | Mature, often very smooth and reliable |
| Crowds | Light to moderate | Light |
| Overall | Excellent — slight edge for variety | Excellent — slight edge for stability |
Both seasons are genuinely excellent; the choice often comes down to personal preference for slightly more dynamic spring conditions versus slightly more settled autumn ones.
Frequently Asked Questions
Is spring better than summer for a first paragliding holiday?
For many pilots, yes — particularly April. The conditions are calmer and more forgiving than peak summer, while still offering genuine variety between coastal and thermal flying. Summer brings longer days and stronger nortada-driven ridge soaring, but spring's gentler overall character often suits a first visit better.
Which spring month should I book if I want to focus on XC?
May is the strongest choice for XC-focused pilots. By this point in spring, the thermal season is properly underway and cloudbase regularly supports real cross-country distances, while conditions are still smoother than the height of summer.
How far in advance should I book a spring week?
Reach out a few months ahead — January or February for an April or May slot — to secure your preferred week, particularly since spring has become increasingly popular. The exact flying days within that week are still finalised closer to arrival, in line with the plan-close approach to chasing the best actual conditions.
