May

Gains

• ↑Reliable 20-22C days in the south while mainland Spain shivers in single digits
• ↑Carnival build-up begins late January in Santa Cruz with parade rehearsals open to spectators
• ↑Whale-watching from Los Cristianos peaks now with calm Atlantic swell and pilot whale pods close to shore

Sacrifices

• ↓British and German half-term refugees push south coast hotel rates 40-60% above October prices
• ↓North coast (Puerto de la Cruz, Anaga) sees more cloud and occasional storm days off the Atlantic

Gains

• ↑Santa Cruz Carnival — second-largest in the world after Rio — fills the capital with costumed crowds and free open-air gigs
• ↑Almond blossom across the Vilaflor and Santiago del Teide valleys turns the mid-altitude trails pink
• ↑Sea temperatures hover at 19C — cool but workable for surfing the El Medano breaks

Sacrifices

• ↓Carnival weekend hotel rates in Santa Cruz triple and book out 6 months ahead
• ↓Trade winds pick up — beach days on the east coast can be windier than ideal for sunbathing

Gains

• ↑Hiking on Teide and through Anaga is at its peak — wildflowers in bloom, no heat haze, temperatures 16-22C at altitude
• ↑Hotel rates drop 25-30% from February before bouncing back at Easter
• ↑Sea warms past 19C and afternoon winds soften — first viable beach swimming month

Sacrifices

• ↓Calima dust storms from the Sahara can knock out two or three days with hazy 30C heat and grit on every surface
• ↓Teide summit cable car still requires a permit booked weeks ahead even off-peak

Gains

• ↑Semana Santa processions in San Cristobal de La Laguna are quieter and more solemn than Seville equivalents
• ↑23C days and 19C nights — first month you can dine outdoors comfortably after dark
• ↑Whale and dolphin season still strong; humpbacks occasionally pass on migration

Sacrifices

• ↓Easter week is the second-biggest price peak of the year for south coast resorts
• ↓School holidays across Spain and UK mean family-heavy crowds at Siam Park and Loro Parque

Gains

• ↑Sea hits 22C — finally warm enough for hour-long swims
• ↑Festival de Musica de Canarias and Mueca street arts festival in Puerto de la Cruz add cultural depth
• ↑Trade winds keep the south coast at 28-30C rather than the 38C+ baking the Spanish mainland

Sacrifices

• ↓Costa Adeje and Los Cristianos hit absolute capacity — sun loungers gone by 9am, restaurants need 48hr reservations
• ↓Hotel rates 80-100% above May for identical rooms
• ↓Calima episodes more intense in summer — Saharan dust can push apparent temperatures past 38C

Gains

• ↑Lowest hotel rates of the year alongside May — south coast 4-star rooms 40-50% below summer
• ↑22C sea persists and Atlantic surf swells return — best surf month at El Medano and Playa de las Americas
• ↑Sunset hours of 7pm allow long beach days without the September heat haze

Sacrifices

• ↓Rain risk doubles compared to summer — full beach day write-offs more likely than September
• ↓UK school half-term in last week pushes Costa Adeje rates back up sharply

Gains

• ↑Lowest occupancy of the year — long-stay apartment rates negotiable down 50% on October
• ↑Hiking conditions in Anaga and Teno reset to perfect after summer baking — 18-22C and greening landscapes
• ↑Whale-watching season opens again with calmer winter Atlantic

Sacrifices

• ↓Wettest stretch of the year — Atlantic systems bring 2-3 storm days a week in the north
• ↓Sea drops to 21C and air cools fast after dark — pool days viable, beach days hit-and-miss
