Spain Weather: How Are the Last Days of April and the May Day Weekend Looking?

Mild but Changeable as Spring Gives Way to Early Summer

Spain's State Meteorological Agency AEMET is forecasting mild but unsettled conditions as the country sees out the final days of April and heads into the first long weekend of May. It is classic late-spring weather — warm enough to enjoy, but with enough cloud and shower risk to keep things interesting.

The Big Picture

• Daytime highs: 21–28°C across popular areas
• Overnight lows: 10–16°C
• Wind: Gentle easterly or southerly breezes, no significant disruption
• Cloud cover: Frequent throughout the period
• Mediterranean sea temperatures: Around 17°C — cool but manageable for early-season swimmers

How It Develops Through the Week

The week starts with the most settled conditions, with cloud coverage increasing and shower probabilities rising from midweek onward — peaking toward the weekend. The pattern is typical of a transitional period between the spring weather system and early summer stability.

Coastal zones remain milder overall compared to inland regions, where showers are more frequent later in the week. Those based along the Mediterranean coast — from the Costa Blanca and Costa del Sol through to the Balearics — can expect the most balanced conditions of the period.

Regional Variations

• Costa del Sol to Balearics: Particularly favourable conditions, with manageable temperatures and the most settled outlook of any region — expect these areas to draw crowds over the long weekend
• Coastal areas generally: Milder and more stable, with sea breezes moderating temperatures
• Inland regions: More frequent showers and scattered precipitation, especially from Wednesday onward

The May Day Bank Holiday Factor

The May 1st Día del Trabajador (Day of the Workers / May Day) is a national public holiday in Spain, creating a long weekend that traditionally triggers a significant wave of domestic travel. Coastal destinations — particularly along the Mediterranean — can expect noticeably higher visitor numbers from Thursday onward as Spaniards take advantage of the break.

For residents and expats planning to use beaches, restaurants or popular attractions over the long weekend, it is worth keeping this in mind. The combination of decent (if not perfect) weather and a national holiday means quieter spots will fill up fast.

Many businesses and public services will be closed on May 1st itself — plan accordingly for shopping, banking and any services you might need.

What to Pack

A light jacket and a compact umbrella are sensible companions for the end of April and early May in Spain — warm enough for t-shirts in the afternoon, but with enough weather variability to make layers useful. On the coast, evening temperatures can feel cooler than the daytime highs suggest.
