Frost Impact
Source: Open-Meteo daily observed temps
- 1 region hit by frost this season
- Southeast GA: High frost at Bud Break (27°F on Feb 24) (20.2% of domestic fresh supply)
> Action: Assess bloom/bud damage within 48 hours and document affected blocks with photos. If you carry crop insurance (APH/WFRP): notify your agent within 72 hours — do not destroy damaged crop before adjuster inspection.
Rain Impact
Source: Open-Meteo daily observed precipitation
- 1 region hit by significant rain
- Southeast GA: 7 rain days during Ripening (Jun 14-22, total 4.7″, peak 2.1″) (20.2% of domestic fresh supply)
> Action: Harvest ripe fruit immediately before next rain event. Rain splitting causes $300-500/acre losses. Consider Parka cuticle treatment for remaining fruit.
Overlap Pressure Index (OPI)
The OPI estimates how many pounds of fresh blueberries are hitting the market in the same weeks across all tracked regions. When multiple regions harvest simultaneously, the supply glut compresses FOB pricing — growers become price-takers. A higher OPI means more overlap and more pricing pressure. (For context, the 2023 cherry season saw ~70% of US volume land in a single month, collapsing FOB prices and leaving ~35% of the crop unharvested.)
Source: Open-Meteo GDD projections + USDA NASS production weights + USDA FAS import volumes
- Supply overlap trending 1% above historical average — Risk: Medium
- Current peak OPI: 359M lbs (week 26)
- Historical peak: 355M lbs
- Peak window: weeks 20–34 (May–Aug)
> Action: Monitor weekly. If OPI continues to climb, discuss diversion strategy with your processor before peak window.
Chill Risk
Source: Open-Meteo hourly temps, Utah model (Richardson 1974)
- Chill % of target needed for normal bloom — below 90% risks delayed/uneven flowering, below 70% risks reduced fruit set
- Regions at risk: San Quintín Mexico (9%, 0% fresh); Fresno CA (0%); Corning CA (75%, 4% fresh)
> Action: Low chill may cause staggered bloom timing and reduced fruit set. Expect an extended harvest window with lower peak volumes.
Season Pattern
Source: RMSE across 4 historical years, supply-weighted
- This season's supply trajectory most closely resembles 2025 (52% similarity), when FOB data limited
- Key driver: early CA start
