Harvest windows for common fruits and vegetables vary by crop and region. Differences between nearby provinces often range from 2–4 weeks for many vegetables. Early or late varieties and odd years can shift peaks by up to six weeks. Describe ranges (for example 2–6 weeks) rather than one single number. That variability makes planning market trips and weekly shops harder for families and visitors.
Regional produce maps and seasonal food guides show what is in season near you. They use interactive province-level maps and month-by-month guides for Spain. Users search by province or city to see local harvest peaks and likely market stalls. The tools let users download printable calendars or CSV files. Cited sources and clear notes on climate and variety effects explain micro-season shifts. That helps shoppers buy fresher, smarter produce.
How to use the map
The map shows local harvest peaks and links each weekly market to likely fresh products.
Step 1: pick a province or city and a month to filter expected produce.
Step 2: view linked markets, opening times and vendor notes to plan your visit.
Quick steps to start
Select a province, choose a month, then filter by fruit or vegetable family.
Use the greenhouse flag to see whether produce is open-field or greenhouse-grown.
Export results as CSV or print a calendar for meal planning and trips.
Mobile and print flows
The map adapts to phone screens and prints clearly on A4.
Save a one-page calendar for a weekly shopping list or export a full CSV for calendar apps.
If maps are embedded in travel notes, use the CSV to add market visits to your itinerary.
Coastal microclimates often advance harvest peaks by roughly two to four weeks compared with nearby inland zones for heat‑responsive crops, though the precise shift depends on crop type and year; present this as a typical range and pair it with the province harvest calendar (weeks) and confidence score so readers can see when that shift applies.
Why seasons differ by province
Seasonality is local and often shifts week ranges between neighbouring provinces.
Climate, soil and cultivar choices change when fruits and vegetables reach peak ripeness.
Production method also matters for timing and quality. The map marks these differences.
For easier scanning, key points are highlighted.
Climate and microclimates
Coastal provinces warm earlier in spring than inland plateaus. This alters harvest weeks.
Islands such as the Canary Islands follow subtropical cycles that differ from mainland rhythms.
Mountain valleys can delay harvest by up to three weeks compared with nearby lowlands.
Varieties and biodiversity
Different varieties ripen at different times even within one province.
Heirloom and local varieties often have shorter shelf life but stronger flavor.
The map notes variety groups where that detail really changes shopping choices.
Greenhouse versus open-field
Greenhouse production brings forward availability for many crops by several weeks.
Open-field produce tends to have a shorter peak window and a different texture.
Knowing which applies locally prevents surprises when a product appears in season early.
Seasons shift because plants follow clear biological cues. Accumulated heat, measured as growing degree days, speeds fruit maturation. Chill-unit buildup and day length affect flowering and fruit set in temperate crops. Soil temperature and moisture change root activity and sugar build-up in fruit. Sheltered coastal zones warm earlier. Mountain valleys lag due to cooler air and slower soil warming.
Protected production, such as greenhouses, decouples crops from ambient heat accumulation and day-length cues. This advances availability by several weeks.
These mechanisms appear in MAPA datasets and IRTA crop calendars when read as ripening windows. That is why maps that show climate drivers and production flags give more accurate local predictions.
How the interactive map works
The map layers regional production, market locations and month-by-month harvest probability.
It combines official datasets, vendor reports and agronomic ripening windows into simple badges.
Each province-month-product cell has a confidence score to help users decide when to shop.
Map layers and filters
Layer choices include crop type, greenhouse flag and DOP or IGP status.
Filters let users show only organic, zero-km or traditional specialty items.
Markets display opening days, busiest hours and vendor-type tags for quick decisions.
Data sources and transparency
The model uses municipal market lists and national agricultural data to estimate peaks.
Authorities and datasets referenced include MAPA and IRTA for crop calendars and guidance.
You can inspect the source layers shown on the map to see the evidence behind each badge.

Map legend: color blocks show typical peak months by crop family in selected province.
For easier scanning, key points are highlighted.
Find markets and monthly assortments
Search by province or market to view the most common stall assortments each month.
Markets list opening times, common stalls and vendor notes on origin and variety.
Filtering by farmer stalls highlights short supply chains and likely fresher arrivals.
Search by province and city
Type your province or city name and the map zooms to market clusters.
Major markets such as La Boqueria and Mercado de San Miguel include vendor notes.
Municipal market lists often come from the local Ayuntamiento or market association.
Market hours
Most markets update opening hours seasonally and the map shows current schedules.
Vendor tags show whether stalls are wholesalers, small farmers or tourist-oriented vendors.
This helps set expectations about quantity, price and variety during your visit.
Product fact-sheets and downloads
Each product page features harvest windows by province, storage tips and substitutes.
Fact-sheets show peak weeks, best storage temperatures and quick recipes for family meals.
The map links each fact-sheet to markets where that product commonly appears that month.
What a fact-sheet contains
Fields include peak harvest weeks, common varieties and DOP or IGP status.
Cold-chain notes explain how fragile produce should be handled for best quality.
Substitute lists suggest nearby alternatives if a product is scarce that month.
CSV exports include province, month, produce, market link and opening times.
Printable calendars fit A4 and show a monthly glance of local peaks for meal planning.
A sample product fact-sheet is available inline so users can copy fields into notes.
A province harvest calendar is more than a month label: a usable version lists rows such as province, municipality, crop, expected peak weeks (calendar ISO week range), greenhouse flag, DOP/IGP status, confidence score and a source field (for example: MAPA datasets / municipal market list / IRTA crop calendars). For example, a CSV row for Valencia might read: Valencia, Alzira, Tomato, weeks 24–29, partial greenhouse, DOP: no, confidence: high, source: MAPA datasets 2024 + vendor report.
Seeing those concrete fields lets shoppers compare nearby provinces and understand whether a listed June peak actually maps to calendar weeks 23–27 in their municipality.
A product fact-sheet example makes seasonality practical. Take tomatoes:
- peak by province in a typical year is Valencia: June–July (roughly ISO weeks 23–30), Cádiz: July (weeks 26–30), Girona: July–August (weeks 27–33)
- agronomic ripening windows shift with variety and year. Storage: best kept at 12–20°C out of direct sun
- avoid refrigeration below ~10°C to preserve flavor—use within 3–7 days for optimal texture
Substitutes when out of season: roasted red pepper purée, canned plum tomatoes or slow-roasted pumpkin for sauce-style recipes. Quick family recipe: chop peak tomatoes, sauté garlic in olive oil, add tomatoes, simmer 10–15 minutes, finish with basil and sea salt for a simple pasta sauce.
Planning your market visit
Plan to arrive early for the freshest selection and best prices at most markets.
Midweek mornings often have steady supply and fewer crowds than weekend peaks.
Late-morning stalls may discount near closing time, especially for perishable items.
Best times to shop markets
Early morning on market day often shows the freshest harvest arrivals.
Avoid peak tourist hours in large city markets to find better prices and service.
Ask vendors about harvest day to know how many hours have passed since picking.
Markets offer seasonal variety and direct traceability from nearby farms.
Limits include variable opening days and sometimes smaller quantities for large families.
Use a simple rule: prefer markets for flavor and traceability. Use supermarkets for fixed convenience.
This approach does not apply when produce is primarily greenhouse-grown or imported year-round; in highly urban areas with no local supply chain, supermarket or wholesale options may be more reliable for steady supply.
Data, sources and methodology
The model combines municipal market lists, MAPA crop calendars and vendor reports for estimation.
Data sources include MAPA and IRTA for regional crop timing.
Regulatory references include Regulation (EU) 2018/848 and Ley 17/2011 for food safety and labeling.
For easier scanning, key points are highlighted.
Confidence and updates
Each province-month-product cell shows a confidence score based on data volume and recency.
The map refreshes vendor reports monthly and official calendars yearly to reflect changes.
A routine check against signals from Mercabarna or Mercasa helps catch short-term shifts in supply.
Partners and studies
Partners include municipal market associations and Slow Food España for specialty items.
The most frequent error in season guides is treating national calendars as locally accurate.
A common case: coastal province shows early tomato peaks, while nearby inland farms peak later.
The paragraph below summarizes the main editorial view and a practical caveat.
The regional map approach works well for planning market visits, but only if users pick the correct province. The method fails when relying solely on national labels or supermarket cues. Use the province filter and greenhouse badge to avoid buying produce that is technically available but not at local peak.
Next steps for market trips
Sign up to receive a weekly CSV export of upcoming local market peaks and tailored itinerary suggestions.
Bring a small cooler or insulated bag for fragile items during warm months.
Ask vendors the harvest week and variety to confirm peak freshness before buying.
